This dataset represents New South Wales 5 metre Digital Elevation Model (DEM) which has been derived from LiDAR and merged together from various projects and will be continually updated.

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 30 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 National DEM 1 Second Percentage Slope product

This Dataset represents a National 25 metre DEM which has been derived from SRTM and LiDAR and merged together and will be continually updated.

This dataset represents Northern Territory 5 metre DEM which has been derived from LiDAR and merged together from various projects and will be continually updated.
