AZ_MohaveCounty_2021_D21

This dataset is comprised of multiple tiles that collectively form the standard one-meter resolution digital elevation model (DEM) produced through the 3D Elevation Program (3DEP). 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 these tiles 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 individual tile in the dataset is distributed in the UTM Zone in which it lies. If a tile crosses two UTM zones, it is delivered in both zones.

Technical Specifications

Source Data: USGS standard one-meter DEMs are produced exclusively from high resolution light detection and ranging (lidar) source data of one-meter or higher resolution.
Seams: One-meter DEM surfaces are seamless within collection projects, but not necessarily seamless across different projects.

Spatial and Vertical Reference

Spatial Reference (CONUS): Universal Transverse Mercator (UTM) in units of meters, and in conformance with the North American Datum of 1983 (NAD83).
Vertical Reference: All bare-earth elevation values are in meters and are referenced to the North American Vertical Datum of 1988 (NAVD88).
Tile Distribution: Each individual tile within this dataset is distributed in the UTM Zone in which it lies. If a tile crosses two UTM zones, it is delivered in both zones.

3DEP Context

The one-meter DEM is the highest resolution standard DEM offered in the 3DEP product suite.
Other 3DEP Products: Nationally seamless DEMs are also available in resolutions of 1/3, 1, and 2 arc seconds. These seamless DEMs were previously known as the National Elevation Dataset (NED).
Public Domain: All 3DEP products are public domain.
