ABSTRACT
Right-of-way business processes have been identified as one of the areas where information
bottlenecks occur in transportation agencies, not only because of the amount of information
involved, but also because of the interdependent nature of these activities. Transportation
projects are associated with parcels whose status change during and after the project based on
information from right-of-way activities. Geospatially enabled decision making tools enhance
data interpretation as well as data retrieval of this information. By using enterprise-level
applications, information sharing between the transportation agency, other jurisdictions, and the
public becomes more efficient. Being able to quickly visualize the status of parcels in a
geospatial environment further enhances the management of resources which, in turn, improves
timely project delivery. This thesis presents a conceptual framework for an information
management system and its geospatial enablement through a logical model for Geospatial
Decision Making Activities (GDMA) in transportation right-of-way offices. The logical model
for GDMA, presented in Unified Modeling Language, includes state machine diagram and data
flow diagram models for tracking the parcel and capturing the geospatial enablement of right-of-
way activities.

1 INTRODUCTION
Right-of-way (ROW) or Real Estate offices in state transportation agencies are
responsible for the appraisal, acquisition, management of land required for federally funded
highway projects and the relocation of those directly impacted by the purchase of that land. The
document and data intensive nature of these activities support the need for electronic
management of information [1]. The automation of right-of-way business functions and
development of business models for an information management system using geospatial
technology provide consistency and efficiency in managing this information effectively.
Many states have streamlined data entry, display, archiving and sharing of information
for one or more of the principal functional areas [1, 2]. However, few have taken advantage of
geographic information systems (GIS) which is closely tied to right-of-way activities particularly
those related to parcel data and the defined transportation right-of-way which are geospatial in
nature [1]. This research focuses on developing a feasible framework for geospatially enabling
the management of information for these right-of-way activities to help improve business
performance. It includes the identification of how right-of-way offices in various transportation
agencies currently use GIS and the state of the practice on the implementation of enterprise-wide
information management systems. With this understanding, this research developed a logical
model for geospatially enabling activities in an enterprise-wide information system for managing
right-of-way business process and information. The enterprise of right-of-way activities consists
of four major functions; Appraisal, Acquisition, Relocation, and Property Management [3, 4].
2
Other areas that are often part of the business of right-of-way offices include aspects of
planning, engineering, and mapping, and are strongly associated with geospatially intense data.
GIS has been used extensively by transportation agencies to support such activities [2, 5, 6].
Similarly, utility management and outdoor advertisement activities have also begun to use GIS
applications [5, 6]. Although several transportation agencies have used GIS as a stand-alone
application for these and other related right-of-way activities, an operational centralized and
systematic enterprise-wide geospatially enabled information management system for principal
right-of-way activities had not been identified at the time of this research as indicated by the
results of a literature survey shown in Appendix A.
Thus, the need exists for the development of a conceptual framework for a geospatially
enabled enterprise-wide right-of-way information management system to meet the business
needs and data processing requirements across the right-of-way office. The implementation of
such a system could result in an increase in the overall organizational efficiency by improving
personnel efficiency and project delivery time, improving the coordination between activities and
communication between individual sections of the right-of-way offices, and enhancing effective
decision making.
This research identifies the opportunities for geospatial enablement in the right-of-way
business process and captures the flow of geospatial data in a prototypical geospatial right-of-
way information management system logical model. This is accomplished by building a
Geospatial Decision Making Activities (GDMA) logical model that reflects two primary aspects
of the geospatial decision making activities. First, the model tracks the flow of the geospatial
parcel data across the right-of-way project process, captured under Parcel Tracking (PT).
Second, it identifies areas where decision making could be enhanced through electronic linking,
3
querying and presentation of data that has a geospatial component associated with it, designated
as geospatial enablement (GE).
1.1 Research Objective
The goal of this research was to develop a conceptual framework for a geospatially
enabled enterprise information management system for state transportation right-of-way offices.
The objectives were to:
Understand the current state of the practice of enterprise-wide geospatially enabled right-
of-way information management systems in transportation agencies;
Identify and define geospatial decision making activities for principal areas in the right-
of-way business process;
Develop a logical model with the corresponding state machine and data flow diagram
models that would explicitly enable the tracking of a parcel in a geospatial environment,
capture the geospatial activities and structure the flow of geospatial data within an
enterprise information management system.
1.2 Research Approach
The first step in the research was to define the current state of the practice of enterprise-
wide geospatially enabled right-of-way information management systems in state transportation
agencies through a literature review. The next step was to develop the logical model for the
enterprise-wide information management system and to identify what activities could be
4
geospatially enabled as well as what data was necessary to track parcels through the process.
From this a Geospatial Decision Making Activities (GDMA) model for right-of-way business
process was developed. A threefold approach was employed, which constituted of:
Conceptualizing the overall business processes of right-of-way offices and their
geospatial decision making activities, including Parcel Tracking and Geospatial
Enablement and standardizing the framework for the model. The business process
diagrams are shown in Appendix B.
Building the overall and GDMA logical models in Uniform Modeling Language (UML)
using Enterprise Architect [7], which are included in Appendix C.
Evaluating the model through detailed discussions with the Utility and Right of Way
Section of PennDOT Office.
1.3 Thesis Contribution
The overall and GDMA models are expected to serve as frameworks for state
transportation agencies to use in developing systems to meet their specific requirements to
geospatially enable right-of-way business processes. This includes:
Providing structure and knowledge base for transportation agencies for integrating geospatial
technology into enterprise-wide right-of-way information management system
Providing insight on the flow of geospatial parcel data within the right-of-way offices to
visualize the significance of incorporating GDMA.
Contributing to the development of new integrated geospatial right-of-way information
management systems or the improvement of existing systems

2 LITERATURE REVIEW
A review of the current state of the practice in information management systems for
transportation agency right-of-way business activities and other relevant agency information
systems was conducted followed by a review of the current architecture and implementation of
geospatial capabilities for management systems in right-of-way.
2.1 Right-Of-Way Information Management systems
Electronic management of information is an important step in improving the efficiency of
any data intensive task. Several states have implemented different types of information
management systems at different levels in their right-of-way or real estate offices. These systems
vary from those that perform a specific activity to comprehensive systems that operate at an
enterprise-wide level. This section provides an overview of existing systems for right-of-way in
use at the time of this research.
These systems have been categorized into three general groups: Standalone Individual
Systems, Small Enterprise Systems, and Large Enterprise Systems and Integrated Systems.
Appendix A summarizes Information/Content Management Systems across states.
7
2.1.1 Stand-alone Systems
Several standalone systems are currently in use by the state transportation agencies.
Typically these systems were developed for a specific activity within the right-of-way project
process like asset management, acquisition, outdoor advertising, etc.
Examples of these standalone systems include the Indiana DOT and Maryland DOT.
Indiana has a Land Record System (LRS) that maintains a database of all the land records [8]. It
is used to track project and parcel activities for the Property Management function. Maryland
has a standalone application for acquisition activities called the Office of Real Estate
Management System (OREMS) which uses a database to store and manage acquisition
information [9, 10]. South Carolina also has a system for their acquisition activities, using a
centralized computer database. It further has an integrated document repository to manage the
right-of-way acquisition activities [9, 11]. New York has an in-house application used to track
payments and generate pay packages [9]. This system is considered a stand-alone system but
may have the capability to link to other processes in design, planning and right-of-way mapping.
A different type of stand-alone system is Wisconsin‟s Transportation Utility and
Management System (TUMS), which is used across the state for highway projects to identify,
track and manage correspondence between offices in accordance with the WisDOT guide to
utility coordination. [12].
An information system under development for determining relocation assistance benefits
for displaced residents and businesses is AASHTO‟s Turbo Relocation. This system is being
developed by Balanced Environmental Management Systems (BEM), in cooperation with
AASHTO and the Turbo Relocation Task Force to provide an interactive software product to
assist states in consistently calculating relocation benefits [13].
8
2.1.2 Small Enterprise Systems
Small enterprise systems either manage information for more than one principal area of
the right-of-way management processes or focus on a single activity, such as document
management across the right-of-way office or agency.
Right of Way Management Information System (ROWMIS), developed by Caltrans, is an
example of one such small enterprise system [12]. This system helps to facilitate the planning
and management of highway projects and parcel acquisition across the state of California. It is a
web-based application with a secure centralized database containing project, parcel and
acquisition information. The system currently does not include appraisal and relocation
assistance apart from the capability to generate forms. Right-of-way Information System
(ROWIS) of Texas, built on SQL Server, is another such system that captures data related to
project setup, mapping, funding, appraisal, negotiations, and eminent domain [11]. This system
also does not include relocation and property management of the right-of-way project process.
Missouri‟s inventory management system called the Realty Asset Inventory (RAI) is a
small enterprise system that is used statewide to manage Missouri‟s realty assets and to identify
properties that are no longer needed for highway purposes [12, 14]. RAI is a computerized
relational database system that documents all sales, leases and excess properties with additional
reference to other realty of interest, such as environmental, cultural, historical, and wetland
mitigation sites. However, the system does not consider other aspects of right-of-way like
appraisal and relocation. It does include an embedded right-of-way parcel acquisition database
that documents acquisition information. Similarly, Nebraska has an application that uses a Lotus
based system that interacts with DB2 and MicroStation called the Automated Right-of-way
Management System (ARMS) [11]. This includes project tracking data and a document
9
generation capability. This system focuses on appraisal with some of the negotiation modules but
does not include relocation and property management aspects of the right-of-way management.
Image Records Management System (IRMS) is another example of a small enterprise
system for Connecticut which creates and tracks the right-of-way documents using an Oracle
database [15]. Although, this system only manages the documents, it is categorized as a small
enterprise system for its enterprise-wide usage. North Dakota uses a small-scale enterprise-level
application called the Records Information Management System (RIM) consisting of multiple
databases which are integrated with File-Net to manage right-of-way records and files [9].
2.1.3 Large Enterprise Systems
Several states have more comprehensive enterprise systems that include most of the
major right of way activities. Virginia‟s Right-of-Way Utilities Management System (RUMS) is
a web-based system that runs on an Oracle database to track the real estate acquisition process on
a project-by-project basis and includes a powerful document management feature [1]. It supports
the right of way and utilities business from the estimate stage through condemnation by tracking
evaluations, negotiations, legal functions, relocation of families and businesses, disposition of
improvements and the relocation of utility facilities. Real Estate Management Information
System (REMIS) of Michigan is also a fully integrated enterprise level information management
system for right-of-way activities featuring immediate updating of reports and schedules [16].
REMIS provides easy access to data through organized folders within the system such as job
folder, parcel folder, relocation folder, condemnation folder etc. Both, RUMS and REMIS
capture most of the functional areas in right-of-way.
10
Real Estate Automated Data System (READS) of Wisconsin (WisDOT) and Appraisal,
Acquisition, and Relocation System (AARS) of the Louisiana Department of Transportation and
Development (LA DOTD) also have large enterprise systems. READS allows users to obtain
status updates on any parcel through streamlining and simplifying the daily highway/real estate
operations [17]. This automated system includes extensive data tracking, report generation and
analysis for acquisition, land inventory, cost estimation, litigation, accounting, property
management, appraisals and relocation. AARS is a web based intranet/internet application using
Oracle database and includes detailed appraisal, acquisition and relocation workflow processing
needs as defined by the LA DOTD Real Estate Section [9, 18].
Other states that have automated Right of Way processes at an enterprise-wide level
include Oregon and Pennsylvania. Oregon‟s Right of Way Data Management System (RWDMS)
is an enterprise content management initiative for right of way project processes [19, 20]. The
system assists in the effective management of the state‟s database of assets through ODOT's
Intranet and FileNet programs. Pennsylvania Department of Transportation‟s (PennDOT) system
called the Right of Way Office Information System is a state-wide system that standardized the
property information into a single electronic case folder for each land parcel. PennDOTs
comprehensive management tool incorporates innovative data-integration capabilities and
supports Right-of-Way appraisal, negotiation, relocation, and property management [6, 21]. It
also includes administration of the project, appraisers and district activities, and tracking of legal
information, along with the management of contracts, task orders, and subcontractors.
Nevada DOTs Right of Way Information Network (IRWIN) is another example of an
integrated system for the management of their right of way information to facilitate streamlined
workflow and common interface solutions [22, 23]. The system supports inventory, access,
11
retrieval, management and reporting of all DOT right-of-way properties and allows users to track
work processes and access stored documents from a centralized information center. The system
integrates with NDOT's GIS, Public Lands Survey System data and video logging system,
electronic document management system and NDOT's Integrated Financial System.
Washington State Department of Transportation is another example for an integrated
system. Its web-based Right-of-Way Management System, known as the Integrated Realty
Information System (IRIS), has helped in structuring their land acquisition processes [12]. The
system provides advanced reporting and management workflow that helps WSDOT with the
efficient management of the property acquisitions, financial data, and project/property costs.
WSDOT plans to expand the system to integrate with GIS to further advance its capabilities by
locating the properties affected by an acquisition and displaying them geospatially.
In general these, larger enterprise systems enable data sharing across divisions of right-
of-way but do not necessarily communicate with other major information systems transportation
agencies. Alabama is one exception that integrates its right of way system with its
Comprehensive Project Management System (CPMS), along with several other systems
including Disadvantaged Business Enterprises program (DBE), Right-of-Way, Storm Water,
Consultant Management, State-wide Transportation Improvement Program (STIP) and
Transportation Economic Land Use System (TELUS) [24]. The right-of-way management sub
system includes 6 major processes; project status, right-of-way mapping, appraisal status,
acquisition, relocation, and leased property as well as a comprehensive reporting module.
Review of the literature indicates that there are several information systems being used
by transportation agencies to support right-of-way activities. Many states employ stand-alone
12
applications while a much smaller number have larger enterprise systems covering all the major
right-of-way business processes.
2.2 Geographical Information Management Systems In Right-Of-Way
The use of geographic information system (GIS) as an analysis and decision making tool
in state transportation agencies has been increasing steadily since the early 1990's. A number of
agencies use GIS to manage, analyze and disseminate geospatial information, making data more
accessible to the decision maker and enhancing the data interpretation capability. When location
is brought to bear on any fundamentally spatial activity, such as transportation, managing and
analyzing information is more effective and powerful.
Thus, geospatial enablement of an information management system adds value to the
system by enabling new methods of integration and ways of visual interpretation of data. Several
stand-alone and some enterprise level applications of GIS are currently in use by transportation
right-of-way offices. Similar to section 2.1, this section groups systems according to their
complexity from stand-alone system to geospatially-enabled information management systems.
In addition, a section on vendor software designed for right-of-way applications is provided.
2.2.1 Stand-alone Systems
Most stand-alone systems use GIS to enhance data viewing and extraction capabilities
and not as an analysis tool. Maryland‟s MdProperty View is an individual system that includes
scanned images of property maps and digitized parcel centroids which link each property to the
State Department of Assessments and Taxation‟s parcel database [6]. The Office of Real Estate
13
uses this system to obtain parcel information for obtaining property information for the
acquisition of right of way for transportation projects. In Texas, San Antonio‟s Right of Way
Application is an Internet-based tool which provides users with access to scanned images of all
past and current right-of-way maps by interactively selecting a location in the district from
pointing and clicking on a GIS interface. San Antonio District right of way professionals, as well
as other DOT employees, use this system to view project information from any computer
connected to the internet/intranet [6].
Geographical Information System based Management Information System (GISMIS)
used by New Jersey integrates its digitized document database with geospatial highway database
of digital roadway plans and right-of-way maps [25]. This is a standalone system used for the
effective management and retrieval of requested documents from a very large scanned digital
document database.
New Mexico‟s Non-Right of Way (NRW) Parcel & Improvement Inventory system is a
standalone GIS application that enables automated generation of NRW Parcel and Improvement
Inventory summary sheets which include geospatial view of parcel locations [6].
Florida has integrated GIS into several departments in its right-of-way office [26]. As an
example, Outdoor Advertising Inventory Management System (ODAMIS) is a client/server
application created specifically for the regulation of outdoor advertising signs. GIS enables users
to view sign locations on a map.
2.2.2 Small Enterprise Systems
As discussed earlier in Section 2.1.2, small enterprise systems either manage information
for more than one principal area of the right-of-way management processes or focus on a single
14
activity across right-of-way office or agency. Highway Access Management System (HAMS) of
Wisconsin can be categorized as a small enterprise-level information management system that
brings together diverse information for managing driveway permits and land division reviews [6,
12]. HAMS has combined the capabilities of several components into one geospatially driven
web interface, enabling straightforward interaction between end-users and the system.
2.2.3 Large Enterprise Systems
Large scale enterprise systems using GIS have only been implemented in Minnesota at
the time of this research, although several states have plans to add GIS capabilities. Right-of-
way Electronic Acquisition Land Management System (REALMS) is a larger enterprise-wide
system that is used by the Minnesota Department of Transportation to support right-of-way
acquisition and land management functions [12]. This web-based, online system allows users to
quickly access and search right-of-way information, visualize and track parcel geometry, and
customize and generate reports. Users are able to search for a record in REALMS and view it in
the map view as well as search for REALMS data in the map and view information from the
REALMS database, thus providing an enhanced integrated geospatial capability to the system.
The following systems have specific plans to incorporate GIS into their systems but are
not currently geospatially enabled. Right of Way Management System (RWMS) of Florida is a
large web-based enterprise system used to record and track all right-of-way activities including
acquisition, eminent domain, relocation, property management, business damages, contracting,
appraisal, cost estimating and funds management using Hummingbird DM product [9, 27].
Although the system currently has no integrated GIS, it has the capability to integrate geospatial
technologies and Florida is working on a building an enterprise GIS. Mississippi‟s Right of Way
15
Parcel Tracking System (PTS), which has the capability to interface with a GIS in the future,
currently manages information flow of the full range of right-of-way activities that include title,
parcel deed, development, appraisal, negotiation/acquisition, relocation, eminent domain,
hazardous material sites and improvements [28].
Oregon‟s FileNet Enterprise Content Management (ECM) application enables access to
the right-of-way data (township, range, file number, record number, deed date, history of deed
sales etc) of each parcel to its users [14]. The data was captured and indexed by the placement of
centriods. Oregon is expecting that the legal description creation process and the appraisal
description process will be automated, after which, relocation, condemnation, acquisition
activities are anticipated to be moved into the system. Eventually, ODOT plans to expand the
application to make mass acquisition cost estimates based on historical data and prices and to
access all documents through a GIS interface that displays the parcel polygon instead of the
current centroids.
2.2.4 Vendor Provided Systems
Off-the-shelf systems developed by vendors include Land and Right-of-Way Acquisition
Management & Record Keeping by the Diversified Energy Software Solutions (DESS) [29]. It is
advertised as a secure systematic application that streamlines the entire life-cycle of the land and
right of way acquisition process, and rapidly provides acquisition and property information. It
covers several right-of-way areas like, Agent Daily Report Logs, Documents and Digital
Content, Agent-Owner Contact Diaries, Court Orders, Tract Financials, Project Financials, On-
Demand Reporting, GIS Map Integration, Special Provisions, Owner Contact Records,
Condemnation, Tie Plats, Title Opinions, Negotiations, On-Demand Searching and Personnel
16
Task Tracking. Similarly, Balanced Environmental Management (BEM) Systems has developed
a system called Paecetrak which is a web-based, GIS-enabled application advertised to manage
the acquisition of properties for transportation system right-of-way [30]. This system is currently
being used for NJTransit capital programs.
DREAMaps is yet another off-the-shelf application developed by Smart Data Strategies
Inc [31]. It is a web-based, GIS-enabled commercial application for right-of-way Management
that has a modular architecture allowing seamless integration by wrapping around existing
workflows with web and desktop platform compatibility, web browser support, and product
security. Illinois‟s Aeronautical Land Acquisition System (ALAS) that has been developed to

considered for the airport and related facilities, is built on Dream Maps [6]. This system also has
an electronic file cabinet module that allows users to scan and link documents to related parcels.
2.3 Summary
This discussion shows that GIS has emerged as an important tool for achieving
standardization and coordination for data analysis and sharing across right-of-way organizations.
Individual applications have limited but measurable benefits for right-of-way. Small enterprise
systems enhance capabilities across one or two areas of right-of-way offices. Large systems
cover multiple right-of-way areas but are not currently integrated with an enterprise GIS. This
identifies the need to provide states with a template for developing an enterprise wide
geospatially enabled information management system to help enhance the overall right-of-way
project process.
17
With data centrally accessible and efficiently organized, the possibilities for extraction
and analysis are greatly expanded. Geospatial integration will help streamline projects from the
initial planning stages through construction and maintenance phases. Further, some
transportation agencies are migrating to maintaining geospatial data warehouses where layers of
information are maintained and served out to agency stakeholders. Integrating information
management systems with these geospatial warehouses is necessary to the effective
implementation of a geospatially enabled system.
This research identifies the need for a comprehensive geospatially enabled application
covering the principal activities of right-of-way. The developed framework is expected to serve
as a working template for state right-of-way offices to move to such an enterprise-wide
geospatially enabled information management system.

ABSTRACT
Given the current state of technology with service oriented architecture, decentralized
information and desktop access to cloud computing and data management, enterprise systems for
managing the information associated with business operations are necessary for improving
efficiency and quality while optimizing resources. In transportation agencies, this is particularly
true in the data intense real estate offices that purchase and manage right-of-way property prior
to construction. This paper presents a structure for a logical model of an enterprise-wide
information management system for transportation right-of-way activities. The business
processes are based on the federal requirements as mandated by the Uniform Act and outlined in
the Federal Highway Administration‟s Office of Real Estate Services Project Development
Guide for appraisal, acquisition, relocation, and property management. The logical model is
developed using unified modeling language, which is considered to be a standard computer
system modeling language rich in well-defined graphical notations for representing complex
systems and provides the structure for developing an operational information management
software program.

3.1 Introduction
The information intense activities of transportation agencies which manage the appraisal,
acquisition and management of land required for highway projects and the relocation of those
directly impacted by the purchase of that land, are often attributed as one of the reasons for
delays in transportation projects. With the increased attention to on-time performance, the need
for more effective management of right-of-way information has been identified as a priority for
these agencies. Use of information technology for automating and right-of-way data entry,
archiving, display and sharing of information for one or more of these principal functional areas
has been in practice by several states and currently provide many benefits to the user [1, 2]. To
fully realize the potential of effectively managing information, an enterprise-wide approach to
coordinating the information associated with right-of-way programs is necessary, and would
result in greater efficiency and improved project delivery, as well as improved interoperability
and data consistency throughout the transportation agency [3]. To assist agencies with building
or expanding these information management capabilities, a standardized framework based on
FHWA‟s Project Development Guide [4], and Uniform Act [5], for such a system has been
developed and presented in this paper.
A summary of how transportation right-of-way offices are currently using information
systems is presented, followed by a discussion of a detailed modeling approach employed for
developing the proposed right-of-way system logical model using unified modeling language
(UML). The model has been designed to encompass the four primary functional areas that exist
in state transportation real estate offices: appraisal, acquisition, relocation, and property
21
management. Geospatial enablement and interoperability with other information systems are also
included in the logical model framework.
3.2 Background
3.2.1 Current Right-of-Way Information Management for Transportation Real
Estate Offices.
Electronic management of information is a principal step in improving the efficiency of
any data intensive task. Several states have implemented information management systems at
different levels in their right-of-way or real estate offices. These systems vary from individual
applications for a specific activity to more comprehensive systems that operate across several
activities. A brief overview of some existing right-of-way systems is summarized in Table 3.1.
Individual systems typically support a single activity. They include applications
developed to manage limited data using desktop computers, or assist in specific computations
with the help of excel spreadsheets, or in generating pay packages or specific documents using
pre-defined templates. Some systems manage information for more than one principal area in a
right-of-way office or focus on a single activity, such as document management, across all areas
in a right-of-way office. These systems are classified as small enterprise systems. More
comprehensive systems that include the majority of right-of-way functional areas are classified
as large enterprise systems and range from customized enterprise database management systems
to complex information management systems such as Alabama‟s Comprehensive Project
Management System (CPMS). CPMS is a broad system that integrates its right-of-way system
with a larger project management system and several other systems like Disadvantaged Business
22
Enterprises program (DBE), Right-of-Way, Storm Water, Consultant Management, State-wide
Transportation Improvement Program (STIP) and Transportation Economic Land Use System
(TELUS) [6]. The right-of-way management system that forms a sub-system to the CPMS
includes six major processes; project status, right-of-way mapping, appraisal status, acquisition,
relocation, and leased property management.

From the literature, information systems with varying levels of complexity and breadth
are currently in use. Only a small percentage are as comprehensive as CPMS and even fewer are
geospatially enabled and integrated into the overall business of a state transportation agency. To
24
assist agencies to move to this level, a logical model has been developed, which captures the
mandated aspects of the Uniform Act and includes hooks to the larger transportation agency
enterprise and the incorporation of geospatial functionality. This provides the necessary
flexibility to allow agencies at any stage of incorporating information management to take
advantage of any or all components of the framework. This paper provides an overview of the
model which will be available through NCHRP 8-55A, Developing a Logical Model for a Geo-
Spatial Right-Of-Way Land Management System [24].
3.2.2 Logical Model Design
In the terminology of software and information systems, the design and implementation
of an information system primarily consists of Conceptual, Logical and Physical Data Modeling,
prior to the actual system development [25, 26]. The Conceptual and Logical Modeling captures
the data, processes, activities and functions of a given business for which the information system
is being developed, while the Physical Modeling describes how the system is implemented in
terms of computer hardware/software, database files, information system screens etc. The
conceptual and the logical model designs are developed prior to the Physical Model design,
which in combination are used for eventual software development.
UML is an accepted set of notation techniques for visually defining, documenting and
representing software intensive systems [27]. This uniform design supports the portability of
framework development for any given model and provides an appropriate platform for modeling
a rigorous and traceable information system for complex right-of-way activities. The model
views available in UML can be divided into two sets; Behavioral Model Views and Structural
Model Views, as shown in Figure 3.1.
25
The Behavioral Model Views capture the dynamic behavior of the system over time [27,
28]. This dynamic view for the system is demonstrated by four UML models or diagrams:
Business Process Model (or Analysis model), Use Case Model, Communication Diagrams, and
Sequence Diagrams. The Business Process Model captures the broad outline of procedures and
the sequence of activities that drive the business. The Use Case Model defines the features or
requirements expected to be provided by the system and captures the interactions within the
system and with entities that are external to the system. Sequence Diagrams and Communication
Diagrams are forms of Interaction Model Views, and are encompassed in the individual use
cases and illustrate the communication between the objects and the messages that trigger those
communications.
The Structural Modeling View defines the static architecture of a model [27, 28]. It
models the elements that constitute the system and the relationships and dependencies between
the elements. The Structural Modeling View consists of three models: Class Model Diagrams,
Component Model Diagrams, and Package Model Diagrams. Class Model Diagrams reflect the
logical structure of the system by capturing the attributes and behavior of the model in its static
view and illustrating the relationships between the classes and interfaces. Component Model
Diagrams depict how a system is decomposed into various components that can illustrate the
structure of arbitrarily complex systems. Package Model Diagrams demonstrate the organization
of packages and their elements, and thus help in organizing use case diagrams, class diagrams, or
other UML diagrams.
The proposed overall right-of-way model supports the abstraction of right-of-way
information and activities that facilitate the design of a comprehensive right-of-way information
management system, with the help of the above described UML Model Views. These individual
26
models depict explicit yet complimentary perspectives of the overall model. A more
comprehensive description and the application of these UML modeling views for designing the
right-of-way system logical model are described in detail in the following sections.

3.3 Proposed Model Architecture
Enterprise architecture planning is the preliminary step to modeling any enterprise-wide
information management system [29]. Defining the enterprise, identifying the actors, outlining
the business processes, and developing the relationships to entities - whether actors, systems or

business processes - outside the enterprise, are necessary to building the model. Since a primary
purpose of the system is to achieve interoperability, the enterprise has to accommodate areas that
will share substantial right-of-way information.
Owing to the complex and diverse nature of business processes throughout the right-of-
way office, it is necessary to define an appropriate scope of the enterprise before designing the
system. Because every state transportation right-of-way office is structured differently to meet
the unique requirements of that state, the scope of the enterprise for this model was identified to
capture the activities outlined in the Office of Real Estate Services Project Development Guide
[4], which was developed by FHWA to provide guidance to the states and local jurisdictions that
use Federal dollars for transportation improvement projects, and to meet the Federal
requirements of the Uniform Act [5]. In addition to project management, the four functional
areas in the model are appraisal or property valuation, acquisition, relocation, and property
management. The enterprise also includes activities related to land being considered during early
project development.
The next step is to identify the major governing actors which include both individual
human and agency actors that are expected to interact with the system. This helps in identifying
roles and establishing responsibilities of the actors prior to model development. This, in turn,
helps in establishing enterprise-wide right-of-way activities associated with these actors,
ensuring interoperability across the enterprise system. This also helps in reducing conflicts that
might arise in building the model and provides further clarity to the right-of-way activities
included in the logical model. Figures 3.2 and 3.3 illustrate the actors and their relationships in
UML notation.
28
The next component of developing the architecture is capturing activities that make up
the business of right-of-way offices as described in the Project Development Guide. This initial
business modeling was fundamental to conceptualizing the right-of-way project processes and
served as the base for modeling the system in UML.

process, with the core areas that make up the enterprise addressed in this research highlighted in
light brown near the center of the figure. Similar diagrams were developed for each of these core
areas. Interoperability with the larger transportation enterprise is incorporated in the system
design by identifying discrete external systems and including these interactions with right-of-
way activities. Figure 3.5 outlines the major systems in UML representation that interact with the
overall right-of-way system.

3.4.1.1 Business Process Model
The Business Process Model, also called the analysis model, is a simplified form of an
activity model that captures the broad outline and procedures that govern the business processes,
in this case, activities in a right-of-way office. The business process model helps in clearly
mapping the scope of the entire system through different activities. For this purpose activity
organizes and specifies the participation of subordinate behaviors, such as sub-activities or
actions, to reflect the control and data flow of a process [28].
This model provides the primary of the proposed system design and is instrumental in
capturing significant activities, events, resources, inputs and outputs that are associated with the
right-of-way business processes. As an example, the upper half of Figure 3.6 shows the Business
Process Model for „relocation planning‟, which focuses on recognizing, at an early stage, any
problems associated with the displacement of individuals, families, or businesses before the
commencement of actions that cause these displacements. The primary actors in the relocation
planning process, identified as a part of the model architecture (Figure 3.4), consist of the
Relocation agent and the Displacing agency.
The relocation agent first identifies parcels with people or businesses that require
relocation assistance from the available list of acquired parcels. This is modeled as the activity
labeled „REL_parcels for relocation‟. Relocation notices specified by the Guide are distributed to
potentially displaced individuals/organization, to help in resolving any identified problems,
minimize the adverse impacts on the displaced persons, and expedite the overall progress. The
activity „Rel_Notices‟ is modeled as a composite activity in the UML design, as denoted by the
infinity symbol in the activity box, and consists of several sub-activities related to each of the
individual notices. The individual activities associated with „Rel_Notices‟ are executed, the
33
status of the affected parcels is updated to reflect the activity. Table 3.2 provides a summary of
all the activities included in the Business Process Model.

3.4.1.2 Use Case Model
The second component of the Behavioral Modeling Diagrams is the Use Case Model.
While the Business Process Model describes both the behavior and the information flows within
the right-of-way system, the Use Case Model provides the system‟s functionality in terms of
actors, use cases, and the relationship between them. A use case denotes a collection of actions
performed by a user (or sub-system) of an enterprise system. This helps in establishing the roles
of the actors by exclusively identifying the functions within the system that are performed by
that specific actor.
This model is usually represented as one or more actors associated with one or more use
cases, as shown in the second half of Figure 3.6. Each of the actors in the use case model
represents a role that is played either by a person or sub-system engaged in the reasonable
functioning of the main system; and each use case represents a discrete unit of work to be
implemented by the main system in collaboration with one or more actors. For example, the use
case diagram for „relocation planning‟ outlines five goals or use cases to be realized by the
system, as required by the identified actors: displacing agency and relocation agent. These five
use cases are summarized in Table 3.3.
Table 3.3: Summary of Use Cases for Relocation planning
Functional area (or
sub-system) Use Case(s)

REL_Geosptial Enablement – Parcel for Relocation
REL_Open Site Office
REL_Notices
REl_Check on displaced persons eligibility for services
REL_Update Distribution Status(es) in the Inventory of
Parcels with Displaced Persons
41
Use Case Models also help in providing traceability or the manner of implementation in the
proposed system for the defined business processes. The use cases identified in the model are
linked back to the business process model with <<implementation>> links to symbolize the
dependant relationship between the models. This feature is used to link model elements or sets of
elements that represent the same idea across model views. For example, Figure 3.6 illustrates
how the business processes of relocation planning are implemented by the corresponding use
cases. To elaborate further, the activity „Parcels for relocation‟ that is defined as identifying the
parcels required for relocation, is implemented by the use case „REL_Geosptial Enablement –
Parcel for Relocation‟ identified in the use case model. Thus, as the model is developed and all
the functional processes and activities are designed and linked to the use cases, the accountability
for each element in the model is established through traceability.
3.4.2 Interaction Model Views
The use case model is further enhanced through the interaction model which is composed
of sequence and communication diagrams. These diagrams are “embedded” in the use case
diagrams and describe the steps taken to carry out the use case.
3.4.2.1 Sequence Diagrams
Sequence diagrams graphically portray the workflow of the implementation of a use case.
These diagrams are primarily composed of objects and the messages dispatched between the
objects that helps in capturing a dynamic view of the system. They typically illustrate the
interaction of the user with the objects and components in the order required to execute a use
42
case. For example, a sequence diagram anchored under the use case „Open Site Office‟ is
illustrated in Figure 3.7.
Figure 3.7: Sequence Diagram for the use case ‘REL_Open Site Office’
The diagram depicts the sequence of steps implemented to realize the goal of „REL_Open
Site Office‟. The decision about „Site_Office_Requirement‟ is first made during project
development prior to acquisition. This requirement is addressed by the Relocation Agent to open
the site office or implement the current use case with the Displacing Agency acting as the
controller. Thus, site office is opened by the displacing agency according to this requirement and
the attributes of the „REL_Site_Office‟ class, which are described in detail under the Class
model, are updated. Simultaneously, as the decision for „Site_Office_Requirement is made, the
status of site office for the corresponding parcel file is updated to either in progress or N/A. As
the goal of the use case is achieved, and the attribute „Status_Site_Office_Establishment‟ of an
instance of the class: „REL_Site_Office‟ is updated indicating its completion.
43
Similarly, the sequence diagrams for other use cases are modeled in relation to the
methods and events supported by the corresponding classes.
3.4.2.2 Communication Diagrams
The communication diagrams represent a combination of information taken from Class,
Sequence, and Use Case model diagrams describing both the static structure and dynamic
behavior of a system. While sequence diagrams model the time ordering of messages,
communication diagrams model the organization of messages i.e., while sequence diagrams
show the order in which the interactions take place, communication diagrams represent which
elements interact with one another. The communication diagrams are also “embedded” in the
corresponding use cases.
Figure 3.8: Communication Diagram for the use case ‘REL_Open Site Office’
Figure 3.8 shows the communication diagram for the use case „REL_Open Site Office‟.
Though semantically it provides the same information as that of the above described sequence
44
diagram, it depicts the inter-object relationships and the exchange of messages among Relocation
Agent, Displacing Agency, Status_Site office and the instance of the class „REL_Site Office‟.
The exchanged communications are labeled in the diagram as 1.1, 1.2, 1.3, and 2.1 to illustrate
the order of the messages exchanged.
3.4.3 Structural Model Views
3.4.3.1 Class Model
A class is defined as an element or an entity of a given system that captures certain
unique features and functionalities of the entity in the form of attributes and methods. A class
model provides an overview of these classes, attributes and their relationships. These diagrams
reflect a static view of the system by depicting what classes interact but not what happens with
their interaction.
For the right-of-way information system, the class model has been developed in
reference to the Business Process Model. The class model for the current system is developed
such that allows it is independent of any language/platform. The classes in this model are
comprised of three elements, the class name, attributes of the class and their behavior. Figure 3.9
illustrates the class diagram for „relocation planning‟, which is a part of the class model for
relocation. The class diagram in the figure depicts the flowing classes:
REL_Notices
REL_Site_Office
REL_Relocation_Planning_Information
REL_Additional Relocation information
Realization and association connectors are used to capture the relationships between
these classes. REL_Relocation_Planning_Information and REL_Additional Relocation
45
information classes are connected with a realization, which is used when the source object
implements or realizes the destination. On the other hand
REL_Relocation_Planning_Information is connected to REL_Notices through a simple
association, which implies a generalized relationship shared by the two model elements. Since
class diagram provides a static view of the system, not all the classes are modeled to have
relationships with other elements in the model, like the REL_Site_Office shown in Figure 3.9.

Separate compartments are used in the representation of classes to illustrate the class
name, attributes, and operations. For the classes depicted in Figure 3.9, the compartment below
the class name captures their respective attributes. The notation that precedes the attribute
indicates the visibility of the element according to the following:
+ Symbol indicates public level of visibility
- Symbol indicates the attribute is private
# Symbol indicates the attribute is protective
Data elements identified in NCHRP Research Results Digest 310 for Integrating Geo-
Spatial Technologies into Right-of-Way Data Management Process [1], helped in providing the
necessary knowledge base for modeling the classes and their attributes for the enterprise-wide
right-of-way logical model.
3.4.3.2 Component Model
The component model shows the structural components of a software system along with
the organization and dependencies among these components. This model, like the class model,
represents a static view of the system depicting the components that contain one or more classes
or interfaces. The components act as the building blocks for the actual information system. Thus,
the component model diagrams help provide a higher level view of the structure of the large and
complex right-of-way information management system.
Figure 3.10 shows the component model diagram for relocation planning linked with
various UML „connectors‟. The six planning components shown in Figure 3.10 include:
Displacing Agency
Notices
47
Site_Office
Parcel
Planning Department
Figure 3.10: Component Model diagram for Relocation planning
The names of those components that are derived from another package in the overall
model are preceded with the deriving package name, as seen for the components
Displacing_Agency and Parcel that are derived from the primary REL_Component Model
Package and Component Model Package-Overall ROW, respectively. The inter-relationships
between the components are illustrated with various connectors as shown in Figure 3.10. The
„assembly connector‟ links the provided interfaces supplied by the Planning_Department to the
analysis Business Process Model

required interfaces specified by the Parcel. A lollipop symbol indicates an implemented interface
and a socket symbol indicates a required interface as shown in the legend. Additional Relocation
Information from the planning department acts as the providing interface to update the required
interface of the Parcel: Attributes/Status. Similarly, notice distribution status acts as the provided
interface for the Notices component. Information flow is used to model the flow of information
between elements, and is used in Figure 3.10 to map the flow between the Displacing Agency
and Site_Office and Site_Office and the Parcel.
3.4.3.3 Package Model
The package model helps in establishing localized system boundaries within the
enterprise by grouping coupled activities within the system. It helps in semantically providing a
structure to all the other UML model views, includes the larger system engineering issues, and
illustrates how the system is decomposed into categories that represent the logical relationships
and dependencies among those categories.
Each of the use case, class, and component models is grouped by their related behavior or
state into packages. For example, as shown in the Figure 3.11, the use case model for relocation
has been grouped into three packages:
REl_Relocation Planning
REL_Relocation Services
REL_Relocation Assistance Payments
The dependencies between the three packages is captured through the connectors labeled
as <<precedes>>, indicating the order of implementation of these packages. As shown in the
49
diagram, use cases grouped under REL_Relocation Planning package model are implemented
prior to both the REL_Services and REL_ Relocation Assistance Payments.
Figure 3.11: Package model diagram illustrating relocation use cases packages
Similarly, uses cases grouped under the REL_Services package occur prior to
REL_Relocation Assistance Payments. Interactions between the major actors and packages are
also illustrated in the package diagram. The dependency connector with the labels <<invokes>>
and <<trace>> between the Relocation Agent, Displacing Agency and the packages in Figure
50
3.11, illustrate the role of the actors in these packages either as directly invoking or tracing the
implementation of the corresponding use cases in the package.
3.5 Conclusions And Future Work
Use of an integrated and interoperable enterprise-wide information management system
for right-of-way business processes could improve efficiency and on-time project delivery for
transportation agencies. Development of an effective right-of-way information management
system requires precisely modeling the activities and information that make up the business.
This study presents an overview of the design of a UML-based enterprise-wide
information management system logical model of this business process for federally funded
highway projects. The model is expected to:
Provide a template for state transportation agencies to support the development of an
enterprise-wide right-of-way information management system that has the flexibility to
meet the unique needs of individual agencies.
Establish a standard structure and vocabulary for effectively processing and sharing right-
of-way information to improve enterprise-wide business activities.
Assist transportation agencies in planning for implementing a system that would integrate
and interact with other existing enterprise-level information systems in the agency, prior
to the investment of funds.
Enhance the integration of the right-of-way business processes into the state agency‟s
overall project delivery process.
51
Although the model provides the necessary structure for building a right-of-way system,
it does not include software development. Business processes identified in the model are
consistent with current federal requirements for right-of-way offices, and the model is designed
to achieve interoperability across right-of-way activities, and to facilitate data integration across
the organization. The design is expected to act as a flexible blueprint for state transportation
agencies to implement an enterprise-wide information management system, accommodating the
unique needs of individual agencies. The full model is available as a part of National Highway
Research Program (NCHRP) Project 08-55A [24].

4 A FRAMEWORK FOR GEOSPATIALLY ENABLING THE BUSINESS AND INFORMATION OF TRANSPORTATION
RIGHT-OF-WAY ACTIVITIES
Kavya Sambana1
Kathleen L. Hancock, Ph.D., P.E.2
ABSTRACT:
Right-of-Way offices in state transportation agencies are primarily responsible for
property appraisal, acquisition, relocation of the affected, and management of the acquired
property. Geographical Information Systems are closely linked to these activities because of the
geospatial nature of parcel data and the transportation right-of-way. Integrating geospatial
capabilities into an information management system can substantially enhance the right-of-way
business process. This paper presents a theoretical framework for geospatially enabling the
business and information of transportation right-of-way activities by conceptualizing a
Geospatial Decision Making Activities (GDMA) framework for transportation right-of-way
offices. Geospatial enablement uses GIS as a platform to integrate geospatial information with
the right-of-way services for the establishment of a standard infrastructure to share data across
the agency enterprise. The current GDMA framework facilitates the integration of right-of-way
activities with a geospatial warehouse architecture. The GDMA models the tracking of the
detailed status of parcels through the right of way process, as well as geospatial enablement
activities in Right-of-Way business processes. The framework is expected to serve as a
knowledge base for transportation agencies to incorporate geospatial capabilities into their
information management tools.

4.1 Introduction
Geospatial technology is playing an increasingly major role in managing information in
and across various sectors like energy, telecommunications, government, transportation, defense,
tourism, natural resources, and many others, by providing the ability to collect, manage and
visualize geographically referenced data and information. When location is brought to bear on
any fundamentally spatial activity, such as transportation, managing and analyzing information is
more efficient and effective. Thus, geospatial enablement of an information management system
adds value to the system by improving how information is integrated, visualized, and used for
decision making. Because of the geospatial nature of parcels and transportation infrastructure,
right-of-way offices in transportation agencies can benefit from incorporating this technology
into their business process.
One of the initial efforts to evaluate the use of Geographical Information Systems (GIS)
in right-of-way offices was provided by the Federal Highway Administration's Office of Real
Estate Services through the 2004 GIS in Right of Way Scan (1). This was followed by A Saka‟s
study „Geographic Information System Implementation of State Department of Transportation
Right-of-Way Programs‟, which highlighted the state of the practice for using GIS in right-of-
way activities at that time (2). These efforts were expanded by K Hancock as reported in the
National Cooperative Highway Research Program (NCHRP) Research Results Digest 310 (3).
This study highlighted the need for the automation of Right-of-Way activities and the
development of data-integration models using geospatial technologies to enable easy and
efficient access to information in the right-of-way offices of transportation agencies. This has
been followed by two peer exchanges in 2007 and 2008 sponsored by FHWA, to promote and
57
encourage both the exchange of experiences and knowledge on GIS applications in the right-of-
way area (4) (5).
Based on this, the National Cooperative Highway Research Program sponsored Project 8-
55A for “Developing a Logical Model for a Geo-Spatial Right-Of-Way Land Management
System”, which developed a logical model for a geospatially enabled information management
system (6). This model provides a template for developing a system to manage the business of
the four primary functional areas in right-of-way offices; appraisal, acquisition, relocation, and
property management. This paper presents the theoretical framework for the geospatial
enablement aspect of the logical model through the Geospatial Decision Making Activities
(GDMA).
A short overview of the current state of the practice is followed by a discussion of the
architecture of GDMA, which includes a structure to track the detailed status of parcels through
the right-of-way business process and incorporate geospatial analysis into those activities that
can benefit from this technology through two sub-models, Parcel Tracking and Geospatial
Enablement.
4.2 State Of The Practice
Use of geospatial technology and GIS in transportation agencies has been increasing
steadily since its inception. Almost state agencies use GIS at some level to manage, analyze and
disseminate data and information. This use varies from desktop-based applications to more
comprehensive Enterprise Geographic Information Systems (EGIS). A summary of applications
of geospatial technology currently in use by transportation right-of-way offices is provided in
58
Table 4.1. These systems range from small systems supporting a single activity to systems used
for more than one principal area to large or integrated systems that support a majority of right-of-
way functional areas.

As demonstrated in Table 4.1, few states have a broad geospatially-enabled enterprise
level system although several have plans to enable existing systems (7).
4.3 Geospatial Decision Making Activities
Right-of-way business processes can use geospatial capabilities for visualization, analysis
and enhanced decision making. This paper proposes a framework called Geospatial Decision
Making Activities (GDMA). This framework has been structured in two sub-components, Parcel
Tracking and Geospatial Enablement. Parcel Tracking tracks the detailed state of a parcel, as it is
managed through the right-of-way project. Geospatial Enablement identifies the potential right-
of-way activities that could benefit from geospatial enablement.
4.3.1 Parcel Tracking
The primary objective of parcel tracking is to provide a visual method to track activities
associated with parcels to manage resources and to provide right-of-way personnel with a tool
for improving efficiency and timely project delivery. Information associated with Parcel
Tracking either indicate completion of a key process, availability of important information that
60
outline the future course of right-of-way activities or signify the occurrence of certain major
right-of-way decisions. This information is divided into three categories; milestones, flags, and
values. Milestones represent critical phases in right-of-way project management and act as
project checkpoints. Milestones can either take a „value‟ or a „flag‟, and they serve as progress
markers. For example, the identified milestones for parcel appraisal include, Appraisal
Technique, Status: Appraisal Review, and Just Compensation. These three milestones indicate
respectively the decision on the appraisal technique for parcel, status of completion of appraisal
review, and the availability of just compensation value, which are critical to monitor the progress
of appraisal. Flags capture the state of completion of activities or processes within each
functional area of right-of-way business, and help to validate the project‟s progression. For
example, the parcel tracking attribute „Status: Appraiser Assignment‟ captures the state of
progress or completion of the task of assigning an appraiser for the parcel. Values capture
important information about parcel entities that add significant value to project scheduling, and
which help to visualize and evaluate parcels in a geospatial environment. For instance,
„Appraisal type‟ is an important decision during parcel appraisal, and is captured as a value in
Parcel Tracking.
Figure 4.1 shows the representation of the captured attributes or states of parcel tracking
framework in a logical process flow chart, and Table 4.2 summarizes these modeled states and
includes a brief description of each state. The states or attributes of parcel tracking correspond to
the activities modeled in the overall logical model (6) in accordance with Federal Highway
Administration‟s Project Development Guide (14).

4.3.2 Geospatial Enablement
Geospatial Enablement models activities that could benefit from geospatial visualization
and analysis within the right-of-way office. In addition to specifying the activity, it also identifies
the required geospatial data, other external resources, and components required to accomplish
that activity in a geospatial environment.
Activities during the project development phase that could benefit from geospatial
integration include alignment selection, conducting environmental studies, evaluating hazardous
waste sites, indentifying parcels required for the project, defining the type of take of the
identified parcel, and analyzing their complexity. One of the primary resources for these
activities and other indentified geospatial activities consists of the parcel cadastre layer
maintained by the state or exclusively by the right-of-way office on a project-by-project basis
(15). Additional geospatial layers, include existing roadway layer, new right-of-way layer or
ROW plans, imagery, utilities, external environmental system, and lease or property
management system.
69
Identified activities for geospatial enablement during appraisal, include reviewing
parcel(s) for value or complexity, evaluating elevation changes affecting the adjoining property,
determining the appraisal technique, valuating the parcel through sales comparison method,
identifying parcels requiring specialty appraisal, and identifying those that have utilities. For
relocation, geospatial enablement can help in identifying the parcels that require relocation,
available properties where the displaced persons or business can be relocated, and the possible
parcels or areas for relocating utilities that exist on right-of-way parcels. For property
management, these activities consist of determining the parcel requirement type, analyzing the
clearance or demolition status of parcel property, determining the cost of earthwork for grading,
justifying the disposal of parcels, and indentifying excess land. Additional resources for these
activities can include a wide range of geospatial layers like topography, soil data, vegetation,
demographic data, and other external resources or systems like appraisal system and historical
parcel sales records etc. Table 4.3 describes these identified activities grouped by right-of-way
functional areas.

72
The GDMA framework, through Parcel Tracking and Geospatial Enablement, is expected
to serve as a knowledge base for the right-of-way offices in state transportation agencies for
integrating geospatial capabilities to better manage the right-of-way business process.
4.4 Significance
Geospatially enabling the management of right-of-way activities provides a wide range of
capabilities that can enhance decision making and improve transportation performance measures,
particularly on-time project delivery. It also helps to explore the spatial relationships across
right-of-way parcels, proposed roadway right-of-way, existing properties, utilities and other
surrounding features, as well as providing enhanced insight and better understanding than static
figures or tables of numbers. Thus, incorporating geospatial technology can extend the
capabilities of managing right-of-way information. This section provides an overview of the
benefits that can be obtained with GDMA.
GDMA helps in providing the right-of-way offices with:
Improved tracking and scheduling of right-of-way project progress
Tracking parcel data is an integral and important part of right-of-way activities to ensure
adherence to project schedules and minimize costs due to delays. Viewing states in a GIS
interface provides another alternative for visualizing and evaluating parcels, personnel and
projects.
73
Improved communication in right-of-way offices
Visualizing information in GIS facilitates better communication in right-of-way offices by
providing increased situational awareness among and across operational areas through
interdependency and shared requirements.
Enhanced right-of-way project decision making
Having situational awareness for successful decision making is important to a broad range of
complex business systems. This can be displayed in a geospatial environment by visually
identifying current and potential delays in various phases of the project. Visualizing parcel
states spatially and relative to one another can inform decision makers of potential locational
aspects as well as standard business considerations.
New options for analyzing activities
Modeling data in a geospatial environment provides enhanced analysis capabilities for many
right-of-way activities, such as, identifying parcels during alignment selection, analyzing
elevation changes of the new roadway right-of-way affecting adjoining property, justifying
the disposal of excess lands, etc.
Greater knowledge about parcel location and enhanced understanding of spatial context
A geospatially enabled right-of-way system enables right-of-way personnel to visualize the
parcel in a larger context with respect to the location of other project parcels and spatial
features like utilities, existing right-of-way/roadway, wetlands, protected land use etc. Thus,
it enhances the contextual understanding of parcels for acquisition, relocation and property
management.
74
Geospatially enabling the management of information through GDMA supports access to
comprehensive tracking and visualization of parcel data, provides new and increased methods for
analyzing data, and improves complex decision making for right-of-way activities.
4.5 Conclusion
The framework for Geospatial Decision Making Activities provides a conceptual basis for
geospatial enabling the right-of-way business process. Implementing GDMA could enable
decision-makers in right-of-way offices to make better-informed decisions, and help increase
efficiency while adhering to on-time project delivery. In summary, the paper presents a structure
to:
Provide knowledge basis for right-of-way offices to integrate geospatial information into
their business
Develop a comprehensive parcel tracking process in a geospatial environment
Contribute to the improvement of existing individual right-of-way departments by capturing
the geospatial decision making activities for appraisal, acquisition, relocation and property
management.
Increase awareness among of the benefits and significance of incorporating geospatial
decision making activities.

5 MODELING AND EVALUATING - GEOSPATIAL DECISION MAKING ACTIVITIES (GDMA)
The conceptual framework for the Geospatial Decision Making Activities, established in
Chapter 4, is used to develop a logical model that integrates seamlessly with the overall logical
model presented in Chapter 3. The current chapter provides a detailed modeling approach for the
design of GDMA in Unified Modeling Language (UML) using standard UML. This chapter also
presents evaluation that was performed to ensure that the Parcel Tracking and Geospatial
Enablement components of the GDMA model effectively represent the flow of parcel and
geospatial data within a transportation agency‟s right-of-way system.
5.1 GDMA Model
The two sub-components of GDMA, Parcel Tracking (PT) and Geospatial Enablement
(GE) are modeled in UML using State Machine and Data Flow Diagram Models, respectively,
using Enterprise Architect, a Computer Aided Software Engineering (CASE) tool developed by
Sparx Systems Pty Ltd [7].
State Machine diagrams, also referred to as State Diagrams, illustrate various states of an
object and the transitions between those states, along with the source or triggering events that
cause the state changes [32]. State machine diagrams provide a dynamic modeling technique to
capture the behavior of an instance of a single class within a system. In its broad sense, a state
represents a particular stage in the behavioral pattern of an object. In a state diagram, these states
are represented in rounded rectangles labeled with their name. Transitions between states are
78
triggered from events. These triggering events invoke the corresponding methods of a state that
result in the change of state of an object. These methods are displayed in the compartment below
the name of a state, and are preceded by the reserved words „do/entry/exit‟ indicating the action
of the operation. Table 5.1 provides an overview of the elements used in a State Machine Model.
Table 5.1: State Machine Diagram Elements
Representation Description
State : Represents a stage in the behavior pattern
of an entity
Method : Represents a UML operation (Captured
in the compartment below the state name)
Initial element : Represents a pseudo-states
indicating the start of flow
Exist Point : Represents a pseudo-states indicating
where the flow is exited
Transition : Defines logical movement from one
state to another
Class : Represents an object that reflects its
structure and behavior within the system through its
attributes and methods. Class name precedes the
source package name in the class model
Package : Contains a collection of classes grouped
under a common name.
Information flow : Represents flow of information
between two elements in the diagram
Initial
Exit
Transition
<<flow>>
79
Data Flow Diagrams (DFD) help to model the system as a network of processes illustrating
the way in which data flows between elements in a system and with other external entities.
Primarily components of a typical data flow include: entity, process, data store, flow connectors,
and the diagram gate [32]. Table 5.2 gives an overview of these elements used in the modeling of
data flow diagrams.

5.1.1 Parcel Tracking State Machine Model
The Parcel Tracking (PT) State Machine Diagram is captures the states of a parcel to
assist in visually following its status through the right-of-way project process. A parcel
undergoes several state changes during its lifecycle, from identification as a right-of-way parcel
to project closing, and allocation as excess or right-of-way. These changes are based on
corresponding ownership details, property valuations, legal procedures, and relocation activities,
which are triggered by different personnel and, in some cases, by contractors. The State Diagram
80
Model for PT shown in Figure 5.1 maps parcel data across the enterprise in a simple yet
comprehensive way and captures the appropriate attributes from the right-of-way data or class
model that triggers the state changes.
The initial transition for parcel tracking is denoted by the Initial element, representing the
default state of parcel at the start of parcel tracking or a right-of-way project. In most right-of-
way offices this initial state could be triggered by the right-of-way activity start date. An event
that enables the parcel transition from one state to another state is reflected through the triggered
operation, and captured under the state method. For example, the state „Project Number‟ is
controlled by the method „entry/Project_ID‟. Methods within the states are controlled by the
attributes of classes modeled in the overall right-of-way system. The triggering methods for each
parcel state are captured in the model using an information flow directed from the source classes
or packages. Tracing the information from the overall class model maintains the integrity of
Parcel Tracking model with the overall right-of-way logical model.
A triggered method may not always readily obtain the necessary information from the
overall logical class model in the right-of-way system. Sometimes the actions are abstracted to
derive the relevant information from one or more related classes and/or class packages of the
overall logical model. Such states are identified in blue text in Figure 5.1. For example, for the
state „Appraisal Type‟, the attribute „Appraisal_type‟ is derived from the „APP_Appraisal
Process Elements‟ package and „APP_Waiver_Establish_Value‟ class.
The states in the model represent the attributes of the parcel class which are categorized
as milestones, flags, and values, as discussed in Chapter 4. Milestones are highlighted in yellow
states, while flags are shown in red text, to provide visual clarity to the model. All parcel
attributes that include flags, values and milestones, are linked to the overall class model with the
81
information flow connector. Attributes categorized as flags, may have a value or be updated to
denote progress or completion stage based on timestamps governed by the start and end dates of
associated composite activities. With this understanding of flag, various states in the PT model,
categorized reflect the progress of a corresponding activity for the parcel, allowing the parcel to
be accordingly visualized in a geospatial environment. For example, the state „Status : Parcel
Evaluation & Inspection‟, reflects the progress of the activity for parcel evaluation. This flag
state can take multiple values or status based on when contact is made with the owner or when
the parcel is evaluated after the parcel visit. Along with other parcel states, these flags are
described accordingly in the model Table 4.2, but are not modeled at a greater level of detail due
to diverse protocols that govern the implementation and execution of flags for each individual
activity.
Four major states „Status_APP, Status_ACQ, Status_REL and Status_PM‟, are designed
as Composite states, with enclosed sub-states. These composite states model more complex
behavior of the system when there is more than one hierarchical level. For example, these states
are updated as the parcel traverses through related activities within the individual functional
areas for Appraisal, Acquisition, Relocation and Property Management, respectively. The
complete PT State Diagram Model is illustrated in Figure 5.1

Figure 5.1: Parcel Tracking State Machine Model Diagram (Cont.)
Thus, parcel tracking is abstracted in UML to represent the finite states of a parcel,
transitions between these states and the triggering actions for these states using a State Diagram
Model. Identified states that represent the stages of a parcel during the course of a right-of-way
project process, help in tracking the parcel visually in a geospatial environment and helps in
understanding functionalities that affect the various states.

5.1.2 Geospatial Enablement Data Flow Model
Geospatial Enablement (GE) framework is captured in UML using Data Flow Diagrams.
Data flows are defined for the GE model to illustrate activities that can be geospatially enabled
as tabulated in Table 4.1. This model helps in capturing the high-level system overview, which
would help designers during the initial analysis and implementation stages of developing an
integrated geospatial information management system to visualize the flow of geospatial data
within the system.
The package diagram that gives an overview of the GE data flow diagrams is shown in
Figure 5.2. It shows the data flow diagram packages for the four functional areas, Project
Development, Appraisal, Relocation, and Property Management. As, indicated in Chapter 4, no
GE activities were identified for Acquisition or Project Closing. Figure 5.2 also shows the major
geospatial resources from a GIS warehouse that constitute common enabling infrastructure.
These layers along with other resources from the geospatial warehouse provide the required
inputs for processes captured in the data flow diagrams for the individual right-of-way functional
areas, shown in Figures 5.3 through 5.6.
The data stores highlighted in red represent geospatial layers, while others denote
standard databases. Red data flow connectors represent the geospatial data flow that results in the
creation of new layers or databases. They represent relations between critical layers in the
warehouse. For example, the relation between the ROW Project Parcels and Parcel Cadastre
Layer, and New Roadway ROW and the Roadway ROW layer, are illustrated through red data
flow connectors. Table 5.3 summarizes the resources in the GE model.

5.2 GDMA Model Evaluation
The GDMA model was evaluated through detailed discussions with a state transportation
agency, Pennsylvania Department of Transportation (PennDOT), to determine if the model
accurately represented how a right-of-way office would track and visualize parcel status and
whether the model has identified the appropriate activities that could benefit from geospatial
enablement. This section presents a brief overview of the evaluation process along with
resulting modifications to the model.
97
5.2.1 GDMA Evaluation Process
GDMA was evaluated through a face-to-face meeting with right-of-way personnel in
each of the primary functional areas, Appraisal, Acquisition, Relocation, and Property
Management, as well as the ROW director for Project Development and Project Closing. After
an overall discussion, processes in each area for the Parcel Tracking and Geospatial Enablement
models were presented and evaluated for practicality and accuracy, and to ensure that the
information captured in the model is compliant with their business practices. The presentation
provided a background of the research, purpose of the meeting, and an overview of the GDMA
model framework The parcel tracking logical flow chart, Figure 4.1, list and description of
attributes of the parcel tracking model, Table 4.2, and list of identified geospatial enablement
activities, Table 4.3, were presented. Discrepancies or variations with the model were
documented, and the model was updated appropriately. The State Diagram and Data Flow
Diagram models presented in the previous section include these modifications.
5.2.2 GDMA Evaluation Results
The GDMA framework was noted to be beneficial for enhancing right-of-way business
practices by the ROW personnel. Based on their comments several changes and additional ideas
have been incorporated to both the Parcel Tracking and Geospatial Enablement components as
documented in Table 5.4 and summarized below.
One critical aspect of the feedback for the Parcel Tracking model consisted specifically
identifying milestones separately from general status for parcels as they move through each of
98
the business functional areas. PennDOT personnel indicated that they have milestone clear dates
to track project progress.
PennDOT personnel indicated that Problem Analysis, Appraisal Review, and Settlement
Value are the tracking milestones, which are captured in the PT State diagram model under
„Appraisal Technique‟, „Status: Appraisal Review‟, and „Just Compensation‟. For, Appraiser
assignment state, it was noted that the appraiser certification has to be verified and that it can act
as a status flag during the process of assigning an appraiser. In addition, PennDOT personnel
suggested that appraiser workload assignment can also be mapped visually in the model based on
the complexity of appraisal process. This has been incorporated in the model by adding the state
„Appraiser Complexity‟. Further, it was noted that „Appraisal Type‟ is referred to as „format
required‟; and „Appraisal Technique‟ as „valuation techniques‟ in their right-of-way office.
Since, the terms are agency specific, appropriate modifications have been made to the
description of states to reflect these considerations, without changing their current names.
In the areas of acquisition and property management, milestones for parcel tracking were
identified, and suggestions for relocation include adding an additional category under the state,
„Secondary Relocation Indicator‟ to address the presence of billboards and commercial signs on
parcels. Additionally, the process „Spatial Analysis: Overlay / Spatial Query‟, for locating
suitable parcels for realigning utilities is identified and added in the model. Finally, under project
closing, two states, „Notice to Proceed‟, and „Federal Voucher Letter‟ have been added to the PT
model.
Additional geospatial activities were suggested for the Geospatial Enablement Model,
especially in the appraisal process, and were added to the model along with the required
resources. These activities included three dimensional modeling to visualize elevation changes
99
and their effects on after property value, locating properties with street view images for initial
appraisal review, comparing paired sales with available historical data in a geospatial
environment, and locating parcels with utilities. These changes to the GE model have been
incorporated by adding the data flow processes: Sales Comparison (Data Analysis), Spatial
Analysis: 3D Analyst, Data Query/ Extraction / Overlay (for the identification of parcels with
utilities). Associated resources added to the model include, „VideoLog Layer‟ and „External
Historical Parcel Sales Records‟.

6 CONCLUSIONS AND RECOMMENDATIONS
This chapter presents the conclusions of the research and recommendations for future work.
6.1 Conclusions
Available literature identifies the need for a comprehensive enterprise-level geospatially-
enabled information management system for right-of-way activities. This research presented an
overview of the design of a UML-based logical model for a right-of-way information
management system, which is expected to provide a flexible blueprint for state transportation
agencies to implement an enterprise-wide information management system, accommodating the
unique needs of individual agencies. The overall logical model is expected to assist
transportation agencies in their planning for implementing a system that would integrate and
interact with other existing enterprise-level information systems, prior to the investment of funds.
The research then focused on developing the framework for Geospatial Decision
Making Activities (GDMA) to provide the required knowledge base for right-of-way offices to
integrate geospatial technology into their business. The GDMA framework, developed in
coordination with the overall logical model, captures the comprehensive parcel tracking process
through the Parcel Tracking (PT) sub-model. The GDMA framework is also expected to
contribute to the improvement of existing individual right-of-way offices, through the Geospatial
Enablement (GE) sub-model, which models the geospatial decision making activities for
different right-of-way functional areas that could benefit from being geospatially enabled.
102
The GDMA model is expected to serve as a template for the use by state transportation
agencies to help develop systems for geospatially enabling the right-of-way business practices,
meeting their specific requirements. It helps in increasing the accessibility of the parcel status to
efficiently manage workloads and also provide required parcel information to an external GIS
warehouse, which could, in turn, help in building a larger integrated enterprise system. Such a
model would provide a mechanism for improving data sharing, management and analysis across
transportation agencies.
The model has been evaluated for its practicality and implementability with PennDOT
Utility and Right of Way Section, and has been modified to reflect their recommendations. The
flexible yet compact framework of the model enables transportation agencies to customize their
existing right-of-way systems or to begin the process of designing a new comprehensive
geospatially enabled system. The PT state machine diagram and GE data flow diagram models
provide the necessary understanding of the functionality of the GDMA framework for
developing such geospatially enabled information management systems.
6.2 Recommendations
Future research consists of expanding the state machine diagrams for the individual states
included in the parcel tracking model to capture the internal transitions within each state. This
helps in enhancing the GDMA model by capturing the detailed flow of data within the enterprise
system required for incorporating parcel tracking. Individual milestones and flags captured in the
parcel tracking component can also be elaborated with appropriate data-integration models to
further capture the information flow required for the execution of each state. Also,
103
implementation or user-interface models can be designed for the developed logical model, to
capture the required artifacts for building and managing the enterprise-wide geospatially enabled
information system in a real-time environment.
