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.
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.
