The 3D Elevation Program (3DEP) data serve as the elevation layer of The National Map, and provide basic elevation information for Earth science studies and mapping applications in the United States. Scientists and resource managers use 3DEP data for global change research, hydrologic modeling, resource monitoring, mapping and visualization, and many other applications. This dataset is a 1 meter resolution, tiled collection of 3DEP project-based data. This dataset was introduced in 2015 with limited coverage of the U.S., but will be expanding as new DEMs from 3DEP quality level 2 or better lidar data are acquired. USGS standard one-meter DEMs are produced exclusively from high resolution lidar source data of one-meter or higher resolution. One-meter DEM surfaces are seamless within collection projects, but, not necessarily seamless across projects. The spatial reference used for tiles of the one-meter DEM within the conterminous United States (CONUS) is Universal Transverse Mercator (UTM) in units of meters, and in conformance with the North American Datum of 1983 (NAD83). All bare earth elevation values are in meters and are referenced to the North American Vertical Datum of 1988 (NAVD88). Data is distributed in the UTM Zone in which it lies. All 3DEP products are public domain.

At this time, USGS 3DEP data access and processing via OpenTopography is only available to the US academic community (with valid .edu addresses). K-12 teachers, international academics, and informal educators are invited to apply by submitting an application for access as described here.

This restriction is for a limited time while we evaluate performance of the system, demand for 3DEP data access, and other factors related to the sustainability of offering this service to all OpenTopography users. All data other than 3DEP are free to access and use: select the OpenTopography, Community Dataspace, or Global & Regional DEMs on the Find Data map or Data Catalog.
