The 1 Second DSM Version 1.0 is a gridded Digital Surface Model (DSM) representing the radar reflective surface (bare earth, vegetation and built structures) as observed by the Shuttle Radar Topographic Mission (SRTM) in February 2000. It was derived primarily from the 1 second SRTM Level 2 provided by DIGO, supported by the Geodata 9 Second DEM in void areas and the SRTM surface water database. 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. The grid spacing is 1 second in longitude and latitude (approximately 30 metres).The DSM covers all of continental Australia and near coastal islands land areas including all islands defined by the available SRTM 1 second elevation and Surface Waterbodies Data Base datasets. © Commonwealth of Australia (Geoscience Australia).
