DEM-H: Australian SRTM Hydrologically Enforced Digital Elevation Model
The Hydrologically Enforced Digital Elevation Model (DEM-H) was derived from the SRTM data acquired by NASA in February 2000. The model has been hydrologically conditioned and drainage enforced. The DEM-H captures flow paths based on SRTM elevations and mapped stream lines, and supports delineation of … australia dem elevation ga geophysical geoscience-australia -
DEM-S: Australian Smoothed Digital Elevation Model
The Smoothed Digital Elevation Model (DEM-S) was derived from the SRTM data acquired by NASA in February 2000. DEM-S represents ground surface topography (excluding vegetation features) and has been smoothed to reduce noise and improve the representation of surface shape. An adaptive process applied more … australia dem elevation ga geophysical geoscience-australia
