3DEP is the elevation component of the National Map. The National Geospatial Program (NGP) provides foundational topographic digital geospatial data through the National Map.

The 3D Elevation Program (3DEP) informs critical decisions that are made across our Nation every day that depend on elevation data, ranging from immediate safety of life, property, and environment to long term planning for infrastructure projects.

The 3DEP products and services available through The National Map consist of lidar point clouds and digital elevation models (DEMs) at various horizontal resolutions. All 3DEP products are available, free of charge and without use restrictions.

The 3D Elevation Program (3DEP) initiative is accelerating the rate of three-dimensional (3D) elevation data collection in response to a call for action to address a wide range of urgent needs nationwide.

The 3DEP products and services available through The National Map consist of standard digital elevation models (DEMs) at various horizontal resolutions, elevation source (lidar) and associated datasets, and web applications and visualization services.

The USGS 3D Elevation Program (3DEP) is in the process of collecting high-quality lidar and IfSAR (for Alaska) coverage for all of the United States and its territories. As this new data becomes available, legacy Digital Elevation Models (DEMs) are being systematically replaced with high-resolution DEMs produced almost entirely from the lidar ...

The 3D Elevation Program (3DEP) was developed to respond to needs for high-quality topographic data and for a wide range of other three-dimensional representations of the Nation's natural and constructed features. 3DEP is based on the results of the National Enhanced Elevation Assessment (NEEA) (http://nationalmap.gov/3dep/neea.html), which ...

The USGS is prioritizing partnerships to complete the 3DEP baseline, while also transitioning towards the next generation of 3DEP coverage for areas where the baseline data are 5 or more years old (8 years in Alaska, Hawaii, and U.S. territories). For locations where there is:

The goal of the USGS 3D Elevation Program (3DEP) is to complete nationwide coverage of lidar data for the conterminous United States, Hawaii, and the U.S. territories and interferometric synthetic aperture radar (IfSAR) for Alaska within 8 years—that is, by 2023--contingent upon sufficient funding. 3DEP is a cooperative program designed to ...
