<abstract>This is a tiled collection of the 3D Elevation Program (3DEP) and is one meter
resolution.The 3DEP data holdings serve as the elevation layer of The National Map, and
provide foundational elevation information for earth science studies and mapping
applications in the United States. Scientists and resource managers use 3DEP data for
hydrologic modeling, resource monitoring, mapping and visualization, and many other
applications. The elevations in this DEM represent the topographic bare-earth surface. USGS
standard one-meter DEMs are produced exclusively from high resolution light detection and
ranging (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). Each tile is
distributed in the UTM Zone in which it lies. If a tile crosses two UTM zones, it is
delivered in both zones. The one-meter DEM is the highest resolution standard DEM offered in
the 3DEP product suite. Other 3DEP products are nationally seamless DEMs in resolutions of
1/3, 1, and 2 arc seconds. These seamless DEMs were referred to as the National Elevation
Dataset (NED) from about 2000 through 2015 at which time they became the seamless DEM layers
under the 3DEP program and the NED name and system were retired. Other 3DEP products include
five-meter DEMs in Alaska as well as various source datasets including the lidar point cloud
and interferometric synthetic aperture radar (Ifsar) digital surface models and intensity
images. All 3DEP products are public domain. </abstract>
<purpose>This data serves as the elevation layer of The National Map, and provides basic
elevation information for earth science studies and mapping applications in the United
States. The data are utilized by the scientific and resource management communities for
global change research, hydrologic modeling, resource monitoring, mapping and visualization,
and many other applications.</purpose>
<supplinf>This is a 10,000 meter by 10,000 meter collection of tiled data. The geographic area
of coverage is described below in the Bounding Coordinates. Additional information for the
3D Elevation Program may be found on https://nationalmap.gov/3DEP/. Data may be downloaded through The
National Map : https://viewer.nationalmap.gov/. Direct links for direct access by automated
services are provided in the Distribution section of this metadata.</supplinf>
