Might try MicroDEM: http://www.usna.edu/Users/oceano/pguth/website/microdem.htm

Ideally, I think you would want to use the 2 meter LIDAR elevation dataset. As far as software, ArcMap with the Spatial Analyst extension can generate slope grids. If I come across any free-ware for doing this kind of thing, I'll post it here. Bert

Hi everyone, I'm trying to figure out how I can get or create a Salt Lake County shape file that delineates where land is flatter than 30% from where it is steeper. Seems like you could create it from contour data, but I don't know how and it might require ArcInfo, which I don't have. Any suggestions? Mike Brown WCEC Engineers
