The National Map
The National Map is envisioned by the USGS as a seamless, continuously maintained, and consistent set of online, public domain, core geographic data. The National Map will serve as a foundation for integrating, sharing, and using other government and private sector data easily and consistently. Eight primary data layers constitute The National Map: digital orthorectified imagery, elevation, hydrography (water), transportation, boundaries, cultural features, geographic names, and land cover.
