Challenge of Incorporating Location Based Information

Specialty GIS/RS servers

– Data isolation– High systems admin

and management costs– Scalability problems– High training costs– Complex support

problems Information not aligned

with Business Processes

Spatial Data

TabularData

GIS/Design MIS

Enterprise DataServer

Geo Engineering Server

Integrating All Information

Relate associated information to spatial locations

– Land records– Property photographs– Satellite imagery– Vector map data– Legal Documents

Value Propositions:

Integrated enterprise data management Consolidated management of spatial operations Greater security and interoperability Enhanced decision support and business intelligence Reduced training requirements Spatially enabled applications

Spatial is a differentiator

• Attributes in database• Geometries in database - but

in proprietary binary format• IT can access geometries via

proprietary interfaces only• Poor integration

Open Spatial Databases

• Attributes and geometries fully integrated in the database

• Spatial is native DBMS type• IT can access geometries via

open standard interfaces• Standard Query Language• Supported by all GIS tools

Oracle9i AS MapViewer

Standard component of Oracle9i AS 100% J2EE compliant Mapping engine Tightly integrated with Oracle Locator and

Oracle Spatial Provides an XML API for defining and

deploying maps via the web Renders data from Oracle8i R3 and beyond

MapViewer: Map

Renders data stored using Oracle’s native spatial data type (SDO_GEOMETRY)

Maps are defined as a collection of themes

Maps may contain a title, legend and footnote

Theme styles can be based on attribute values (thematic maps)

GIF, BMP and PNG image formats

Oracle9i AS Location Based Services

Java APIs - ingest online web services: geocoding, routing, mapping, YP, traffic, mobile positioning

Region Modeling - associates services (billing, personalization) by (geographic) “regions”

Location Caching - caches caller’s phone number & location to minimize wireless network pinging.

Location Privacy - manages based on LBS service type, permissions, and subscription.

Location Marks - Manages user defined locations of interest (home, work, PIM addresses)

Oracle Spatial in Action

New York City

Department of Information Technology & Telecommunications

– Developed standardized digital basemap for all agencies 6,000 miles of underground

pipes 1 million water/sewer

connections 32,000 sq. miles of

Infrastructure Data 7,500 digital photographs

The Office of Emergency Management created a public site for emergency preparedness

– Extensively Used To Support 9/11 Response and Recovery

The consolidated spatial data warehouse was the foundation for NYC’s response to the recent tragedies

– First responder deployment– Critical infrastructure management– Road closures– Evacuation areas– Damage assessment

The Office of Emergency Management created a public site for emergency preparedness

– Hurricane flood risks and evacuation routes – Heat Advisory “cool down locator” (pools, senior centers,

community centers) Department of Health uses the system to track instances of

West Nile Virus

Oracle in Action:

New Jersey

Office of Emergency Management

State unable to catalogue emergency response resources, publish plans, deploy

Different naming conventions, different systems, many private sector owned Assets

Response to emergency events severely compromised

– Lessons learned from 9/11 assisting NYC

City of Edmonton Integrated, central repository

for spatial and relational data– Replaced 49 disparate land

apps &166 databases– Citywide sharing of

standardized data Data feeds: land registry and

surveys, utilities and phone co., tax assessments, Dept. of Public Works

Users: engineers, planners, cartographers, city officials and departments, mortgage lenders, citizens

FAA – Oracle Spatial Site license for Oracle Spatial US Airspace Boundary Crossing Application

– Oracle Spatial functions to calculate intersection of flight paths and US airspaces.

– Linear Referencing to interpolate the time and altitude for entry/exit points of US airspace.

– Accurately charge foreign carriers for the amount of time in US airspace.

(Longitude, Latitude, Altitude, Time)

Computed(Lon/Lat, Alt, Time)

FAA – Oracle 9iAS (MapViewer)

New 9iAS customer, influenced by MapViewer feature of 9iAS.

Developing MapViewer application for flight plan visualization

Spatial analysis to project current flight position to next waypoint of original flight plan.

Another example of LRS functionality

Georectified/Georeferenced images supported

10g: Topology/Network Manager

New topology data model– Storage based on topological elements (or primitives)

Nodes Edges Faces

– Topological element stored once in the database– Topological integrity maintained by database

Functionality– Topological element can be associated with one or more

features– General purpose support and analysis of networks– Connectivity, adjacency and attribution at link level

10g: Spatial Mining & Analysis
