This service represents a hill shade (ground surface topography) and excludes vegetation features which has been dervied from the National DEM SRTM 1 Second. The sun angle used is 315 degrees azimuth and 45 degrees altitude. It is intended for large scale use for low lying area feature identification. The processing method is decsribe in the 1 Second SRTM Derived Product User Guide (Geoscience Australia, 2011)

This Service represents the 5 metre Digital Elevation Model (DEM), with national coverage. It is derived from merged LiDAR and various projects. New data will be added to the service as it becomes available.

This metadata file and associated files contain metadata for the Geoscience Australia Kakadu LiDAR project carried out in 2011. This metadata is for the Digital Elevation Model created as 1m grid generated from the LiDAR point data classified as ground. The grid was generated employing a point to TIN and TIN to grid point process with nearest neighbour interpolation. The DEM was generated in ESRI ArcGIS V10 format.
