Nationwide one-second DEM launched
The CSIRO, the Australian National University (ANU), the Bureau of Meteorology, Geoscience Australia and the Defence Imagery and Geospatial Organisation have just completed building the finest resolution national computer model of Australia's ground surface topography and river networks. . The new one-second – or 30-metre resolution – hydrological Digital Elevation Model (DEM) incorporates rivers […]
