Colorado mapping resources
Everything you'd need for naming exit ramps, setting city names, and almost all road names.
- Map View uses the ESRI GIS viewer and displays CDOT's recent GIS data (2010?).
- Highway Data appears to use Navteq data for the base layer (tile graphics) with a CDOT GIS overlay for the numbered routes in Colorado.
- Windshield is CDOT's own StreetView for all numbered routes in Colorado, this is especially useful for naming exit ramps.
