The United States Geological Survey's (USGS) Earth Explorer data portal is a one stop shop for obtaining geo-spatial datasets from its extensive collections. Users can navigate via interactive map or text search to obtain Landsat satellite imagery, Radar data, UAS data, digital line graphs, digital elevation model data, aerial photos, Sentinel satellite data, some commercial satellite imagery including IKONOS and OrbView3, land cover data, digital map data from the National Map, and many other datasets. Users can search by exact location via the interactive map or input specific coordinates to view what data types are available.
USGS Global Visualization Viewer
Make your own maps with a variety of layers and search the U.S. Geological Survey's satellite and aerial data.
TIGERweb is a web-based system that allows users to visualize our TIGER (Topologically Integrated Geographic Encoding and Referencing database) data in several ways. The applications allow users to select features and view their attributes, to search for features by name or geocode, and to identify features by selecting them from a map. The TIGERweb applications provide a simple way to view our TIGER data without Geographic Information System (GIS) software and without downloading data. The applications use our TIGERweb REST Services. The TIGERweb WMS and TIGERweb REST Services allow users to integrate our data into their own GIS or custom web-based applications.
The National Map
As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response.
Open source geographic data imaging engine that allows users to create geographic image maps.
