Product Specification (PDF File)

Integrated Mapping

Providing the tools to manage the map that works with your applications.

GeoAuthor® from International Computer Works, , powered by MapInfo Professional, delivers the correct measure of ease-of-use and sophistication to leverage investments made in existing GIS data providing the user with the tools to manage local GIS data or enhance TIGER/Line Shape Files maintaining TIGER topology.

GeoAuthor® is designed to provide the user with an easy-to-use set of tools with which to create a project for a county or county equivalent using TIGER/Line Shapefiles provided by the US Bureau of the Census. Once the project is created the GeoAuthor® permits the user to make edits to the geometry and tabular attributes of the map data. This includes realigning TIGER to local geometry (i.e. road centerlines, parcel maps, aerial photos, etc.), adding missing features (i.e. streets, water, landmarks, etc.), modifying tabular attributes (i.e. names, address ranges, ZIP Codes, etc.) and use the diagnostic routines in GeoAuthor® to confirm the integrity of the data. GeoAuthor® also includes GeoPoints© which is designed to create and maintain geographic databases of points and tabular attributes. Both GeoAuthor and GeoPoints provide conflation tools with which to leverage externally created GIS data for easy updates.



Intuitive, Menu driven

GeoAuthor® provides object based tools making it easier for you to manage, edit and update your base map starting with data that other agencies have already built. With capabilities such as:

  • Manage street names with up to five aliases
  • Conflate both map objects and tabular attributes with a simple select and Add Segment or Add Point
  • Manage street names with up to five aliases
  • Create intersections with auto-distribution of addresses
  • Add new streets using either precise or distributed address ranges
  • Realign a lengthy shoreline as easily as drawing a polyline
  • Easily edit addresses and ZIP codes for all the roads in the county
  • Context sensitive HELP and Computer Based Training closed captioned videos
  • Use Build Layers to create map layers including:
  • Create intersections with auto-distribution of addresses
  • Add new streets using either precise or distributed address ranges
  • Realign a lengthy shoreline as easily as drawing a polyline
  • Easily edit addresses and ZIP codes for all the roads in the county
  • Use Build Layers to create map layers including:
• Roads and points for geocoding
• Boundaries from closed areas of the linear network which can then be used to define city limits, precincts, response zones, etc
• Shorelines of water bodies.
• Streams, creeks, ditches, etc.
• Fence lines, power lines, etc.
• Railroads and Airports
• Major Roads  

 



Use with other Applications

Designed for ease-of-use, GeoAuthor® is strategically positioned to help you use the power of GIS data in concert with other ICW applications to address the mission critical needs of your office.



Convenient Editing Tools

Map data built with GeoAuthor® can be used with:

Traditional GIS
Expanding Technologies
1. Maintain your center street line file with tools designed to manage the data. 1. Change Name Change the name of a single segment or for all segments with the same Reference Number. For roadway features the user may edit a primary name and up to 5 alternate feature names.
2. Create closed boundaries that share the same geometry as local data. 2. Populate your map enabled web site with data whether you serve up GIS or display maps for your end-users.
3. Distribute the enhanced data (17 to 40 layers) to users who can benefit from a shared map library. 3. Use the enhanced data with vertically integrated applications such as GeoSchools, GeoChoice, GeoPoints SQL, GeoBuilder, or GeoElections also from ICW.
4. Use the enhanced data for redistricting school zones, election precincts, or 911 dispatch. 4. Link the demographics of your target audience to the enhanced boundaries using the positional accuracy of your geocoded data.
5. Geocode data using ZIP5 as a generalized boundary file loosely fitting street segments. 5 Geocode data using ZIP5 as an accurately specified attribute of the street segment.

 

Boundaries


GeoAuthor® delivers the correct measure of power!


Following is a list of the items in the GeoAuthor® pull down menu along with a brief overview of the functionality that each tool or command option offers.

1. Change Name

Change the name of a single segment or for all segments with the same Reference Number. For roadway features the user may edit a primary name and up to 5 alternate feature names

 

2. Change Attributes

Permits the user to have direct edit control over the left and right address information for a segment (to and from addresses and 5 digit zip codes) and the MTFCC for that segment.

 

3. Flip Record

Reverse the line direction for a road segment converting the line to a forward encoded segment while maintaining the left and right attributes on the correct side of the line.

 

4. Distribute Addresses

Provides two methods of assigning address ranges to multiple road segments (Proportionate and Unit Length).

 

5. MultiUpdate

Update the name, ZIP Codes, MTFCC and Revert Graphics for a group of selected segments. For roadway features the user may edit a primary name and up to 5 alternate feature names.

 

6. Add Segment

The user can add a new line then with a dialog box enter the name and other attributes.

 

7. Trace

Assists the user to keep track of edits to the geometry made using MapInfo Tools.

 

8. Create Intersection

When the user adds a new linear feature (i.e. street or road, railroad, airstrip, creek, stream, etc.) and it intersects an existing line, an intersection must be created and where necessary addresses distributed.

 

9. Shape Point

The user can modify the shape of a segment as easily as redrawing the feature. This can result in the addition of shape points, deletion of shape points all transparent to the end user.

 

10. MDN

Is a simple toggle between the setting “Move Duplicate Nodes in the Same Layer or None of the Layers”. If two or more lines intersect at the same location they are said to share a node. With MDN on, the user can select a line and move the shared node and all of the lines will move with the first line. This is also referred to as rubber banding.

 

11. Construction Point

This command allows the user to snap a point to a line.

 

13. Retire TLID

In the TIGER system, TLIDs do not get deleted, they get retired. This tool allows the user to tag an object and GeoAuthor® will assign a standard MTFCC value that indicates the new status of the line.

 

14. Table Maintenance

Consists of a group of submenus that provide access to GeoAuthor functions which manage files as opposed to manipulating individual or groups of objects in a table. Following is a list of the items and a brief overview of the functionality represented by this menu group.
Save Tables will save multiple tables relieving the user from the need to perform multiple saves.
Revert Tables will revert multiple tables relieving the user from the need to perform multiple revert table commands.
Pack Tables will pack multiple tables relieving the user from the need to perform multiple packing operations.
GeoAuthor® QC is a set of diagnostic tools designed to make it easier to complete the task of creating the best map data possible. Following is a brief description of each of the menu items:
Missing ZIPCodes will create a file that contains a list of records that are missing a 5-digit ZIP Code.
Duplicate Addresses operation will generate a file that contains a list of records that have duplicate or overlapping addresses for both primary and alternate feature names.
Check Snap operation will generate a map table of points that identify the end points of lines that are not connected to an adjacent line, but fall within a user specified snap tolerance.
Intersection Points
will build a table of points that are snapped to the intersections of the segments within a table of linear features (i.e. lines and polylines).
Compact Name List operation is designed to eliminate names that entered into the GeoAuthor® database and subsequently modified, leaving the initial name unused.
Degenerate Objects will analyze the contents of TGR1 for zero length line objects and present the user with a table of points that mark the location of the objects to be repaired.
Duplicate New TLIDs detects multiple occurrences of records and reduces the set to one, additionally. it creates a list of records that have duplication of the three fields used for geocoding.
Foreign Objects detects and removes none linear objects from a table such as text or points. Additionally. it creates a list of multi-section polylines if present to be corrected by the user.
Import Data will import TIGER/Line Files or data that was created in another GIS project. These files are imported into a project for editing with the GeoAuthor® and GeoPoints.
Build Layers will generate enhanced layers of linear features and an table of atomic polygons. The user can add columns to the atomic polygons and subsequently build different polygon layers.
Revert Graphics will restore the symbology of a file edited with Preferences on to the original styles.

 

15. Project

The Project menu options create and manage directories and files. A GeoAuthor® database consists of many directories and files. For the user’s convenience the database is managed as a project. Following is a brief overview of this functionality.
Create allows the user to register and create a project.
Add allows the user to register an existing project.
Rename allows the user to rename a registered project.
Delete allows the user to remove a project from the system.

 

16. Setup

This feature allows the user to select a project to work with.

 

17. Conflation Layer

Automates the conversion of linear networks such as road center lines to be converted from an externally created format and data structure (e.g. 911, GIS, Planning, etc.) to the data structure used by GeoAuthor for easy updates using this external data.

 

18. Preferences

Allows the user to change the graphical representation for features that are edited, or verified. Also, permits specifying the number of feet in a unit for incrementing addresses in Unit Length addressing.

 

19. Exit GeoAuthor®

This option exits GeoAuthor® and removes it from the MapInfo Menu Bar. To get GeoAuthor® back the user must launch MapInfo from the GeoAuthor® Icon or execute the Tools>Run MapBasic Application.
