Districting for ArcGIS Add-on
An ESRI Solution-Based Add-On
Districting for ArcGIS allows you to create defined groupings of geographic data, such as census tracts, ZIP Codes, and precincts, by creating a districting plan. The Districting for ArcGIS Add-on has a simple user interface for fast configuration of geographic representation and analysis of configuration alternatives. Once you have established the base data, such as counties or ZIP Codes, you can group the units simply by selecting them in ArcMap. Districting for ArcGIS can help you analyze population densities, housing breakdowns, income and race statistics, and other data.
Redraw Political Boundaries, Sales Territories
Local, state, and federal government agencies must periodically redraw political boundaries to account for shifts in population. GIS gives government a better way to handle redistricting. Using GIS transforms the redistricting process from an arduous and lengthy manual operation into a convenient process where you can easily create and consider alternative scenarios to find the best available solution. Districting for ArcGIS also is useful for defining police beats; sales territories; voting, school, and fire districts; and numerous other boundaries.
Make Organizing and Previewing Alternative Plans Easier
The Districting for ArcGIS Add-on is built on top of ESRI's Desktop technology and uses both ArcCatalog and ArcMap. ArcCatalog is a convenient way to organize and preview districting plans. ArcMap contains an easy-to-use interface for viewing and editing districting plans. To use the districting add-on you need, at a minimum, an ArcView license. Districting for ArcGIS supports data in personal geodatabase, shapefile, coverage, and ArcSDE geodatabase formats.
The installation is a self-extracting executable and includes sample data.
Districting for ArcGIS includes an online help file, providing help on specific topics, as well as a comprehensive tutorial to guide new users through the entire districting process. While technical support is not available for free add-ons, you can send questions to email@example.com. The ReadMe.txt file is included on the Getting Started page, and below in the Supporting Files section there is a 'Districting for ArcGIS What's New 9.2' document describing the latest changes.
To successfully run the Districting for ArcGIS Add-on, you will need to have a Windows operating system (2000, NT, or XP) and ArcView 8.2, or 8.3, or 9.0 with Service Pack 1, or 9.1, or 9.2 with Service Pack 2.

To start using Districting for ArcGIS, you need to go through the following steps:
- Run Districting for ArcGIS.exe to install the Districting for ArcGIS add-on.
- Start ArcMap. You must turn on Districting for ArcGIS Add-on by going to Tools ->Extensions. Check the Districting box and click close.
- Toggle on ESRI Districting Extension toolbar (either go through View ->Toolbars or right click in the toolbars region near the top of ArcMap).
- Once plan workspaces and plans are created, you can start ArcCatalog and expand to your plan workspaces to view them.
- On some versions of the Windows NT operating system, ArcCatalog has the following limitation: If any TXT file exists somewhere along the path of a data file, including the folder where the data file is located, when you use the Add Data button to add a data layer the ArcMap.exe process appears to be running in Windows Task Manager after you dismiss ArcMap. To avoid this, delete all TXT files along the path for your data files.
- Plan workspaces (personal geodatabase MDB files) created in the current release of ArcGIS cannot be used with previous versions of ArcGIS.
When you try to install Districting for ArcGIS, you might get a message saying "Another version of Districting for ArcGIS is already installed. Please use Add/Remove programs to remove the presently installed version before installing this one." But when you try to uninstall the old version in Add/Remove in Control Panel, it says it's already uninstalled. In this case, run RegEdit and remove the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\AV_REDIST_EXT so you can install the new version.
