National Geospatial Program
The mission of the National Geospatial Program is to provide National topographic information to advance science, support government, enlighten citizens, and enable decision making. The NGP provides a foundation of digital geospatial data representing the topography, natural landscape, and manmade environment of the United States.
Topographic Maps
US Topo maps, OnDemand Topo maps, and the Historical Topographic Map Collection (HTMC) are produced by the National Geospatial Program of the USGS.
3D National Topography Model
The 3D National Topography Model (3DNTM) is a new initiative that updates, improves, and integrates USGS elevation and hydrography data to support the most demanding scientific requirements and enable data-driven decisions across user communities. Key elements of the 3DNTM are in place or under active development.
