Description
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 smoothing in flatter areas than hilly areas, and more smoothing in noisier areas than in less noisy areas.
This DEM-S supports calculation of local terrain shape attributes such as slope, aspect, and curvature that could not be reliably derived from the unsmoothed 1 second DEM because of noise.
There are several areas with unexpected negative values: close to Canberra around (150.443044, -35.355281) with values of -55 and in Western Australia around (124.84, -16.44) with -43.
