    Collection Overview: USGS logo

    The USGS 3D Elevation Program (3DEP) Datasets from The National Map are the primary elevation data product produced and distributed by the USGS. The 3DEP program provides a variety of resolution raster elevation data of the conterminous United States, Alaska, Hawaii, and the island territories. This one-meter DEM product is produced exclusively from high resolution lidar source data.

    USGS Standard DEMs represent the topographic surface of the earth and contain flattened water surfaces. Each DEM dataset is identified by its horizontal resolution and is produced to a consistent set of specifications. Standard DEMs are characterized either as project-based or seamless. Project-based DEMs (e.g. 1-meter) are available for the full areal extents of projects when produced from lidar, and represent the topographic bare-earth surface This one-meter 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.

    Note: Metadata for the different USGS raster products can be found here. All 3DEP products are public domain. For more details about the USGS 3DEP DEMs visit this USGS page.
