The drainage catchment DEMs provide a regional product filling the gap between localised high resolution tiled data and the national low resolution mosaic provided by the 1-second Shutte Radar Topographic Mission dataset. The drainage catchment DEMs fill a critical gap, providing data to support efficient planning, research and decision-making by government, industry, and research communities. DEMs for available drainage catchments are delivered as a mosaicked product in raster format. Metadata for each drainage catchment is supplied in word document and shapefile format. The shapefile enables users to inspect metadata in a Geographic Information System. Value: Data used at regional scales to represent and provide understanding of ground surface topography. Supply of models as a single file allows easier use and wider uptake, for example in assessments of water movement through the landscape or the potential movements of fires.
