National Geospatial Program
Home
The National Geospatial Program (NGP) provides a foundation of digital geospatial data representing the topography, natural landscape, and manmade environment of the United States. Customers can incorporate NGP geospatial products and services into their decision making and operational activities. NGP data and derived products and services can be accessed through The National Map Data Download.
Topographic Maps
US Topo maps and the Historical Topographic Map Collection (HTMC) are produced by the National Geospatial Program of the USGS.

Defining technology operational readiness for the 3D Elevation Program—A plan for investment, incubation, and adoption
The 3D Elevation Program (3DEP) is an acquisition strategy that uses data from commercial remote sensing technologies to create three-dimensional maps of the United States and U.S. territories. Currently, light detection and ranging and interferometric synthetic aperture radar are the two commercial technologies being used to provide three-...

The 3D Elevation Program and energy for the Nation
High-resolution light detection and ranging (lidar) data are used in energy infrastructure siting, design, permitting, construction, and monitoring to promote public safety through the reduction of risks. For example, lidar data are used to identify safe locations for energy infrastructure by analyzing terrain parameters and identifying and...

Improving geospatial query performance of an interoperable geographic situation-awareness system (IGSAS) for disaster response
Disaster response operations require fast and coordinated actions based on the real-time disaster situation information. Although Volunteered Geographic Information (VGI) or crowdsourced geospatial data applications have demonstrated to be valuable tools for gathering real-time disaster situation information, they only provide limited utility for...
