Daves Redistricting App
This application requires Silverlight 2.0 (from Microsoft), which runs on both Mac and Windows.
Main Features
- Select state and number of congressional districts (CDs) [up to 500 CDs can be created, allowing you to do legislative districts, too.]
- Use mouse to sweep across map and assign block groups or voting
districts to CDs
(block groups usually contain about 4 voting districts; using the larger size makes things more manageable) - Assign block groups according old CDs with one click
- Pan/Zoom
- Save/Open your work in XML (saved in isolated storage)
- Use 2000 census numbers or updated (2008) census estimates
- Show/Unshow city, county and old CDs
- Create area maps of zoomed in areas
- Save state and area maps in XML
(A separate Windows app can read the XML and produce JPGs; Silverlight won't allowing saving as JPGs directly; the Windows app and the schema for the XML are available for download; see Redistricting App Help)

Notes
- The data and especially polygon files can be large (7MB for Texas polygons; 2.9MB for Washington polygons), so loading after you select a state is slow.
