Another source for geo-referenced map data is the usgs, they are free from the Illinois state geographic survey. Also, I have had real good luck using another free app called GRASS which runs on a ton of different platforms. The learning curve is a little steep but moves quickly with the tutorials. I used the two sources above to generate 2.4Ghz coverage maps in CU a couple years ago: http://www.wefel.net/wireless/maps.html On Mar 2, 2004, at 4:05 PM, Wendy Edwards wrote: > Hi, I found some free GIS data files (ESRI shapefiles) for Champaign > County courtesy of the US Census Bureau and ESRI.
