- USGS 7.5 MIN TopoMaps (2000). This data set consists of images derived from scans of U.S.G.S. 7.5 minute quadrangle maps (Digital Raster Graphics). The images form a set of 4 seamless tiles, 5,000 m on a side for each map, from which the map collar information was removed. Images are GeoTIFF files in NAD83, UTM zone 18.

- Counties data.
- Large Scale Watersheds
- Statewide Data
- Plus lots of ther data
