    dct:description """These data are Digital Surface Models (DSM) derived from interferometric synthetic
        aperture radar (ifsar) data. A DSM is a 3 dimensional representation of surface elevations
        in an area, including elevations of man-made structures and vegetation. The USGS performs
        minimal quality assurance and no reprocessing of the DSM data. USGS distributes the DSM data
        as received from the contractors, partners or contributing entities. """ ;
