The Missouri Geological Survey's Geosciences Technical Resource Assessment Tool (GeoSTRAT) makes a large amount of geoscience information available in interactive map form, including:

The Virginia Department of Mines, Minerals, and Energy provides a large amount of information on Virginia's geology and natural resources in interactive map form, including:

• Surface geology
• Geothermal suitability
• Sinkholes
• Water wells
• Mineral resources and mining operations

The map allows users to select multiple layers that can be overlain on each other. By doing this, users can see how different features are related.

The University of Texas' interactive map of Texas Gulf shoreline change rates is an initiative of the The Texas Shoreline Change Project. The map utilizes a colored scale to indicate the magnitude of shoreline change from the 1930s to 2012, with the option to view changes since the 1930s, 1950s, or 2000.

The Maryland Geological Survey, in cooperation with the U.S. Geological Survey, maintains a state-wide network of groundwater observation wells. The data from these wells is used to create an interactive map of groundwater levels in Maryland. The map provides both historical and recent groundwater reading levels across a range of aquifers in the state of Maryland.
