    dct:description """This is a tiled collection of the 3D Elevation Program (3DEP) covering Alaska only,
        and is 5-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 5-meter DEMs are produced exclusively from interferometric synthetic aperture radar
        (Ifsar) source data of 5-meter or higher resolution. Five-meter DEM surfaces are seamless
        within collection projects, but, not necessarily seamless across projects. This DEM is
        delivered in the original resolution, with the original spatial reference. All elevation
        units have been converted to meters. These data may be used as the source of updates to the
        seamless 1/3 arc-second DEM layer, which serves as the elevation layer of the National Map.
        Other 3DEP products are nationally seamless DEMs in resolutions of 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 in Alaska include lidar point
        cloud and interferometric synthetic aperture radar (Ifsar) digital surface models and
        intensity images. All 3DEP products are public domain.""" ;
