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 Elevation (3DEP)
3D Elevation (3DEP)
3DEP is a cooperative program with a goal of acquiring nationwide lidar (IfSAR in AK) to provide the first-ever national baseline of consistent high-resolution elevation data – both bare earth and 3D point clouds.

Absolute accuracy assessment of lidar point cloud using amorphous objects
The accuracy assessment of airborne lidar point cloud typically estimates vertical accuracy by computing RMSEz (root mean square error of the z coordinate) from ground check points (GCPs). Due to the low point density of the airborne lidar point cloud, there is often not enough accurate semantic context to find an accurate conjugate point. To advance the accuracy assessment in full three-dimension
Precision of headwater stream permanence estimates from a monthly water balance model in the Pacific Northwest, USA
Stream permanence classifications (i.e., perennial, intermittent, ephemeral) are a primary consideration to determine stream regulatory status in the United States (U.S.) and are an important indicator of environmental conditions and biodiversity. However, at present, no models or products adequately describe surface water presence for regulatory determinations. We modified the Thornthwaite monthl

Integrated Map of North America (IMNA) Workshop
Representatives from the national mapping agencies of Canada (Natural Resources Canada (NRCan)), Mexico (Instituto Nacional de Estadística y Geografía (INEGI)), and the United States (U.S. Geological Survey (USGS)), met in Ottawa, Canada to begin integrating data products from each country into an Integrated Map of North America (INMA). This workshop was facilitated and sponsored by the Pan...

3D Elevation Program (3DEP) - Your Source for 3D Elevation Data
High quality 3D elevation data are critical to flood risk management, resource management, conservation, alternative energy, agriculture, infrastructure management, and a broad range of other nationally significant applications. 3DEP is a cooperative program, managed by the USGS on behalf of the community, with the goal to complete national coverage of 3D elevation data in 8 years.
