    dct:description """This data collection of the 3D Elevation Program (3DEP) consists of Lidar Point
            Cloud (LPC) projects as provided to the USGS. These point cloud files contain
            all the original lidar points collected, with the original spatial reference and units
            preserved. These data may have been used as the source of updates to the 1/3-arcsecond,
            1-arcsecond, and 2-arcsecond seamless 3DEP Digital Elevation Models (DEMs). 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. Lidar (Light detection and ranging) discrete-return point cloud data are
            available in the American Society for Photogrammetry and Remote Sensing (ASPRS) LAS
            format. The LAS format is a standardized binary format for storing 3-dimensional point
            cloud data and point attributes along with header information and variable length
            records specific to the data. Millions of data points are stored as a 3-dimensional data
            cloud as a series of geo-referenced x, y coordinates and z (elevation), as well as other
            attributes for each point. A few older projects in this collection are in ASCII format.
            Please refer to
            http://www.asprs.org/Committee-General/LASer-LAS-File-Format-Exchange-Activities.html
            for additional information on the .LAS file format. All 3DEP products are public domain. """ ;
