Chapter 3: Managing Land Data

3-1

Chapter 3

Managing Land Data The LandNet application of GESXplorer manages cartographic data. Cartographic data can consist of

township and range, survey block and section, roads, pipelines, rivers or any number of other landgrid and

cultural features. In LandNet, display layers can be automatically created during data import.

LeaseMap is the GESXplorer manager for lease data. Lease management includes lease ownership,

working interest, expiration dates, etc. Layers can be custom-made from the data in LeaseMap showing a

variety of data postings.

When mapping land data in a new Project area, the first step is to import the data. LandNet converts the

data for use in GESXplorer using one of the several available conversion methods developed for several

different industry-standard data types. LeaseMap will import lease data in GeoGraphix LDF/LDF2

format. A spreadsheet importer is included in LeaseMap to facilitate importing lease data from a

spreadsheet. Additionally, lease data can be manually entered or selected from layers in GeoAtlas.

This chapter is intended to show the basic techniques for importing and viewing land data. First, cultural

data and landgrid data will be imported. The resultant layers will be viewed and modified in GeoAtlas.

Then, a database consisting of lease data will be generated, and layers displaying various lease information

will be displayed.

In this workflow you will learn to:

� Import cultural data using ProjectExplorer.

� Import a landgrid using LandNet

� Display and QC layers in GeoAtlas

� Generate a LeaseMap database

� Make a layer displaying lease data

� Make a thematic map

� Filter lease data using QueryBuilder

� Map filtered data

Importing Cultural Data

Data for many GESXplorer applications can be imported through ProjectExplorer in ASCII format.

ProjectExplorer is capable of importing a variety of cartographic data standards. In this chapter, cultural

data in GeoGraphix CDF ASCII file format will be imported into the project.

When data is imported into LandNet, it can be built into a layer automatically. Landgrid data can also be

identified as a landgrid database. The distinction between the two is:

Display Layer

LandNet can create a Display Layer upon data import as a set of cartographic features and textual

annotations that can be shown in a map presentation. If imported as a Display Layer, the data is stored as

a shapefile for display in GeoAtlas.

Landgrid Database

Landgrid data imported as a Landgrid Database is a collection of base-map grid polygons (public land

survey) stored in the LandNet database. Well data may contain a textual “legal” description of the

location of a well measured from a base-map grid polygon. The Landgrid Database can be used to

calculate the latitude and longitude of the well from the textual “legal” description in Jeffersonian surveys.

The landgrid database can also be used to distinguish individual lease holdings in LeaseMap.

Landgrid data can be made into a Landgrid Database and a Display Layer simultaneously upon import.

LandNet can manage any type of cartographic entity (roads, streams, pipelines, etc.) and allows the user to

add their own entities. Users have control of the display attributes for each entity including line style,

color, and label characteristics.

1. Activate ProjectExplorer. Select File >> Imports >> Land >> GeoGraphix CDF Import to

display the Import dialog box.

GESXplorer

� Note

When data is imported into GESXplorer, the format of the data MUST be designated so

that the software will use the correct conversion method. Importing data using the wrong

conversion method can result in invalid data values including latitudes and longitudes,

which can result in unreasonable project extents. CDF Cartographic data format is an

industry standard supplied by many vendors. There are also third party vendors who

supply software to convert other formats to CDF format.

Using GeoAtlas to Display and QC Data

The GeoAtlas tool provides a powerful display and graphic editing system similar to many CAD

packages. In addition, objects displayed within GeoAtlas may be linked to other GeoGraphix modules,

or interfaced with other Windows applications.

The GeoAtlas tool provides powerful graphic editing capabilities for modifying the appearance of maps

and cross sections. This robust environment permits correcting overposted text, filling areas with patterns,

reshaping contours, etc. GeoAtlas can also be used to perform spatial queries (point-and-shoot) to

retrieve data from WellBase, PRIZM, ZoneManager, and SeisBase

Each GeoAtlas map can contain an unlimited number of layers. For example, a single map might contain

a cartographic layer generated by LandNet, a layer showing leases constructed from LeaseMap, a

contour layer built by IsoMap, and a well layer from WellBase. A collection of layers can be saved to a

GeoGraphix GeoAtlas Map File (*.gmp). This file contains all the parameters necessary to reconstruct

the exact layout of the map, but does not duplicate the actual Layers, metafiles, or bitmaps comprising the

GeoAtlas Map. This ensures that the most current layers are displayed on saved maps.

In Page View, it is possible to group and arrange maps, cross sections, and other graphics into a montage.

GeoAtlas is an extremely flexible tool that allows users to attach metafiles, bitmaps, text documents, or

pictures to a map in Page View. User-created title blocks, legends, company logos and scale bars may be

inserted to add the finishing touches to the display.

Displaying Layers in GeoAtlas

1. Open GeoAtlas by selecting Start >> Programs >> GeoGraphix >> Discovery >> GeoAtlas

or by clicking on the icon from the Discover Toolbar in ProjectExplorer. The GeoAtlas – Getting Started dialog box opens.

The Getting Started dialog is designed to assist new users with the basic workings of GeoAtlas.

For this course, the dialog will be turned off (it can be turned on again be selecting Tools >> Open Startup Dialog, or Tools >> Show dialog on startup from the menu bar in GeoAtlas).

Using GeoAtlas to Change Entity Attributes

GeoAtlas includes the option to change entity attributes (line type, text size, and color, etc.) in a Layer

displayed in Map view. The new settings are automatically saved to the layer. In this part of Chapter 3

GeoAtlas will be used to change the color and boldness of section lines, change text size and enable and

disable entities on the display using a powerful feature in GeoAtlas called Layer Display Attributes.

The Layer Display Attributes feature will be demonstrated numerous times in the course.

Changing Color and Boldness of Section Lines

1. With the map displayed in the GeoAtlas window, right-click on the screen to display a drop-down

menu and select Edit Layer Display Attributes. (You may also click the icon on the tool bar).

Changing Landgrid Lettering Size

Map annotation sizes within GESXplorer are specified in real-world units. For example, a well symbol

may be defined as 100 feet in height, however, the actual size of objects changes according to the scale of

the final output. This means that at an output scale of 1:24000, the well symbol will be 0.05 inches on the

map, whereas if the map scale is changed to 1:50000, the symbol will be 0.025 inches. GESXplorer

defaults most items to display sizes that are reasonable for typical Project areas.

1. Using the Zoom cursor, zoom in on an area of the GeoAtlas display of about six sections in size near

the middle of a township so that both section numbers and township/range direction and numbers are

displayed on the screen. Right-click on the map and select Edit Layer Display Attributes to open

Using LeaseMap

LeaseMap is the GESXplorer mineral interest and leasehold mapping system that enables analysis of

land ownership for a geographic region. Using LeaseMap, a company’s land ownership positions can be

mapped along with those of partners and competitors.

LeaseMap is a sophisticated mapping tool that meets the needs of experienced land professionals. Since

LeaseMap is fully integrated with the other GESXplorer applications, tract and lease information can be

managed and displayed along with well, landgrid, cultural, seismic, and contour data. This provides an

integrated work environment for land professionals, geologists, and geophysicists. Some of the basic

applications of LeaseMap are outlined in this workflow.

Using LeaseMap you will learn to build a list of business associates, create new tracts, import lease data,

display lease data in GeoAtlas, and use QueryBuilder to filter the LeaseMap database

Building a List of Business Associates

Business Associates in LeaseMap jargon are legal entities, like individuals or corporations, which can

enter into contracts. Therefore, both lessors and lessees are business associates. Before you can create a

complete ownership tract or lease, you must first have created a list of Business Associates to be the

mineral interest owners or lessees.

1. Open LeaseMap from ProjectExplorer by clicking on the LeaseMap icon , or from the Start

menu at the bottom of the screen by selecting Start >> Programs >> GeoGraphix>> Discovery >> LeaseMap. (Alternatively, LeaseMap can be accessed through the Tools >> GeoGraphix

command from any of the other GESXplorer modules. The Default Settings dialog box appears.

To scroll through two or more records, use the scroll arrows on the LeaseMap toolbar after the

Business Associates manager is re-opened.

� Note:

The only required field in the Business Associates records manager is the Name field.

LeaseMap organizes the data displayed in lists by alphabetizing the records according to

the Name field. Therefore, it is recommended that Business Associates data be entered

using a last name first format.

7. To close the Business Associates window, click on the close button in the upper right corner of

the window.

Creating Tracts

Ownership tracts are parcels of land with a unique set of mineral interest owners. The parcels that make up

an ownership tract do not have to be contiguous. Tracts can be created automatically by importing tract

data in LDF/LDF2 or Spreadsheet formats or manually by Metes/Bounds, Landgrid, GeoAtlas, or

Coordinate methods.

1. In the LeaseMap menu bar, select File >> Tract Navigator, or use the Tract Navigator button

on the toolbar to open the Tract Navigator.

Making a Thematic Map

All leases displayed on the layer created above are displayed in the same red stippled pattern. The nature

of shapefiles allows patterns and colors to be varied based on certain attributes associated with entities on

the layer (thematic mapping). Information stored with a layer can be used to theme a map based on several

properties. This is a very powerful feature that can be used on nearly any GeoAtlas layer.

Commonly with any software including GESXplorer, there are menu commands or quick toolbar buttons

that can be utilized to perform a certain workflow. In the case of thematic mapping, the Edit Layer

Display Attributes menu command or the Define Thematic Symbols button on the Active

Layer toolbar can be utilized to create a thematic map.

In this workflow example, the lease data will be color-coded based on the lessee using the Edit Layer

Display Attributes menu command. The Define Thematic Symbols button method will be

demonstrated in a later workflow task.

1. With the Leases layer displayed as the Active layer in GeoAtlas click the Define Thematic

Symbols icon .
