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)

3DEP Map

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.

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

The accuracy and consistency of 3D Elevation Program data: A systematic analysis

The 3D Elevation Program (3DEP) has created partnership opportunities to increase the collection of high-resolution elevation data across the United States, eventually leading to complete coverage of high-resolution, three-dimensional (3D) information from light detection and ranging (lidar) data across the entire country (interferometric synthetic aperture radar in Alaska). While 3DEP data are co

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.
