National Geospatial Program
Home
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. Accessible through The National Map Data Download, customers can incorporate NGP geospatial products and services into their decision making and operational activities.
Topographic Maps
US Topo maps and the Historical Topographic Map Collection (HTMC) are produced by the National Geospatial Program of the USGS.

NHDPlus High Resolution (NHDPlus HR)---A hydrography framework for the Nation
Reliable and accurate high-resolution mapping of the Nation’s waters are critical inputs to models and decision support systems used to predict risk and enable response to impacts on water resources. It is necessary to know where the water is and how it relates to features beyond the stream network like forests, cities, and infrastructure. An up-...
