  description: "U.S.-wide digital elevation data at horizontal resolutions ranging\
    \ from one to sixty meters.\n\nThe [USGS 3D Elevation Program (3DEP) Datasets](https://www.usgs.gov/core-science-systems/ngp/3dep)\
    \ from the [National Map](https://www.usgs.gov/core-science-systems/national-geospatial-program/national-map)\
    \ are the primary elevation data product produced and distributed by the USGS.\
    \ The 3DEP program provides raster elevation data for the conterminous United\
    \ States, Alaska, Hawaii, and the island territories, at a variety of spatial\
    \ resolutions.  The seamless DEM layers produced by the 3DEP program are updated\
    \ frequently to integrate newly available, improved elevation source data.  \n\
    \nDEM layers are available nationally at grid spacings of 1 arc-second (approximately\
    \ 30 meters) for the conterminous United States, and at approximately 1, 3, and\
    \ 9 meters for parts of the United States. Most seamless DEM data for Alaska is\
    \ available at a resolution of approximately 60 meters, where only lower resolution\
    \ source data exist.\n"
