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 enhance TIGER/Line
Shape Files while 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. 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
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
- Create intersections with auto-distribution
- Add new streets using either precise or distributed
- Realign a lengthy shoreline as easily as drawing
- 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,
| • Shorelines of water bodies.
Streams, creeks, ditches, etc.
• Fence lines, power
• Railroads and Airports
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:
||Maintain your center
street line file with tools designed to manage the data.
||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.
||Create closed boundaries that
share the same geometry as local data.
||Populate your map enabled web
site with data whether you serve up GIS or display maps for
||Distribute the enhanced data
(17 to 30 layers) to users who can benefit from a shared map
|| Use the enhanced data with
vertically integrated applications such as GeoSchools, GeoChoice,
GeoPoints SQL, GeoBuilder, or GeoElections also from ICW.
||Use the enhanced data for redistricting
school zones, election precincts, or 911 dispatch.
|| Link the demographics of your
target audience to the enhanced boundaries using the positional
accuracy of your geocoded data.
||Geocode data using ZIP5 as an
attribute of the street segment.
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
|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
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.
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.
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
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
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
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®
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.
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
Add allows the user to register an existing
Rename allows the user to rename a registered
Delete allows the user to remove a project
from the system.
This feature allows the user to select a project to work
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.
|18. 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.
