USGS Scans

United States Geological Survey

The USGS (United States Geological Survey) produces and maintains a vast collection of maps of the United States, including topographic, geologic, and hydrologic maps. These maps are often created by field teams who physically survey and document the landscape, and are then scanned into digital format for broader distribution and accessibility. USGS scanned maps are digital versions of the original paper maps that have been georeferenced, meaning that they have been assigned specific geographic coordinates and can be accurately overlaid on other digital maps or satellite imagery. This allows users to see the original features and markings of the paper maps, such as contour lines, elevation markers, and other important geographic information, while also being able to navigate and explore the map in a digital format.
