The 1 second SRTM derived DSM Version 1.0 is a 1 arc second (~30m) gridded digital surface model (DSM) that represents ground surface topography as well as features above the ground such as vegetation and man-made structures. The dataset was derived from the Shuttle Radar Topography Mission (SRTM) data acquired in February 2000, supported by the GEODATA 9 second DEM in void areas and the SRTM Water Body Data. Stripes and voids have been removed from the 1 second SRTM data to provide an enhanced and complete DSM for Australia and near-shore islands. This 1 second DSM forms the source for the 1 second DEM with vegetation offsets removed (ANZCW0703013355) and for smoothed and drainage enforced versions that are expected to be released in 2010. The grid spacing is 1 second in longitude and latitude (approximately 30 metres).
