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 <i> project-based</i> 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). <b>Data is distributed in the UTM Zone in which it lies</b>. All 3DEP products are public domain.</p> <p><a href='https://www.sciencebase.gov/catalog/item/543e6b86e4b0fd76af69cf4c'>Click here</a> for a broad overview of this dataset</p> U.S. Geological Survey 3DEP Program https://www.usgs.gov/ resourceProvider null info@opentopography.org https://opentopography.org distributor en geoscientificInformation -159.78846410171542 -64.56326559357852 17.672461661181462 49.39806061755148 https://doi.org/10.5069/G9NP22NT HTTP Standard Internet browser Download Navigate directly to the URL for data access and download.
