the tells What us data map
Nationally consistent geospatial data from The National Map enable better policy and land management decisions and the effective enforcement of regulatory responsibilities.
The National Map is easily accessible for display on the Web through such products as topographic maps and services and as downloadable data. The geographic information available from The National Map includes boundaries, elevation, geographic names, hydrography, land cover, orthoimagery, structures, and transportation. National Map GIS data download and other related applications for working with our topographic data are available on our Data Delivery site.
The National Map Themes. The National Map TNM supporting themes include boundaries, elevation, geographic names, hydrography, land cover, orthoimagery, structures, and transportation.
Other types of georeferenced or mapping information can be added within TNM Viewer or brought in with TNM data into a GIS to create specific types of maps or map views and or to perform modeling or analyses.
The National Map Corps. NMCorps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.
