The North Carolina Geological Survey has produced an interactive online version of its geologic map of North Carolina. Users can click on the individual units for more information, and a PDF of the map is available for download.

In addition to the state geologic map, users can also view information and maps of North Carolina's physiographic provinces and major geologic features.

The North Dakota Department of Environmental Quality provides information about surface water quality across the state in interactive map form. The map includes:

• Detailed water quality data for lakes, rivers, and reservoirs
• Water quality impairment status for lakes, reservoirs, rivers, and streams
• Detailed hydrology for the state, including all surface water bodies and surficial aquifers

Additional map layers include information on administrative boundaries and the state's air, rail, and road transportation networks.
