This service represents the National Digital Elevation Model (DEM) 1 Second product derived from the National DEM SRTM 1 Second. The DEM represents ground surface topography, with vegetation features removed using an automatic process supported by several vegetation maps.

This dataset represents Victoria 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 45 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)

The Digital Elevation Model (DEM) 25 Metre Grid of Australia derived from LiDAR model represents a National 25 metre (bare earth) DEM which has been derived from some 236 individual LiDAR surveys between 2001 and 2015 covering an area in excess of 245,000 square kilometres. These surveys cover Australia's populated coastal zone; floodplain surveys within the Murray Darling Basin, and individual surveys of major and minor population centres. All available 1 metre resolution LiDAR-derived DEMs have been compiled and resampled to 25 metre resolution datasets for each survey area, and then merged into a single dataset for each State. These State datasets have also been merged into a 1 second resolution national dataset.

This dataset represents Western Australia 5 metre DEM which has been derived from LiDAR and merged together from various projects and will be continually updated.
-
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 Service represents the National DEM 1 Second Hydrologically Enforced product derived from the National DEM SRTM 1 Second and National Watercourses, lakes and Reservoirs
