The Shuttle Radar Topography Mission (SRTM) digital elevation dataset was originally produced to provide consistent, high-quality elevation data at near global scope. DEM-S represents ground surface topography (excluding vegetation features) and has been smoothed to reduce noise and improve the representation of surface shape. The Smoothed Digital Elevation Model (DEM-S) was derived from the SRTM data acquired by NASA in February 2000. DEM-S: Australian Smoothed Digital Elevation Model.The DEM-H captures flow paths based on SRTM elevations and mapped stream lines, and supports delineation of … The model has been hydrologically conditioned and drainage enforced. The Hydrologically Enforced Digital Elevation Model (DEM-H) was derived from the SRTM data acquired by NASA in February 2000.

This version contains both ground level samples and items above ground level (such as buildings, bridges, trees etc). It was generated from LIDAR data taken in the spring between 20.
