Webfoot Census Maps Credits
These maps are an outgrowth of a project I did for Tamara Munzner's Information Visualization class. I built upon many many years of work that other people did.
To make the Census overlay maps, Ducky used
- Data from the 2000 U.S. Census (from the SF1 data file).
- Shapefile boundry files from the U.S. Census Bureau
- Thomas Boutell's gd library,
- Frank Warmerdam's Shapelib library,
- Eugene Eric Kim's cgihtml library,
- Pete Freitag's query-string parsing code
- Google Maps API.
Mapki, the Google-Maps group, Mike Williams' tutorials, and of course the Google Maps API Documentation were all very helpful. Mike Williams has been extremely helpful.
Before version 2 of the API, I had to work hard to display census data in context, so I did a overlay with ideas on how to implement code from Will James of onNYTurf.com, and Alan Taylor of Google Maps Transparencies. (In version 2, I combine my data tiles with the "hybrid" layer, so no longer need to do the transparent overlays trick.)
