AI-generated Key Takeaways
-
This collection features a variety of Digital Elevation Models (DEMs) for Australia, including a 5-meter bare earth DEM derived from LiDAR and hydrologically enforced and smoothed DEMs derived from SRTM data.
-
The collection also includes a National Intertidal Digital Elevation Model (NIDEM) providing a 25-meter resolution representation of Australia's intertidal zones.
-
Several datasets derived from Landsat imagery are available, offering insights into land cover, water observations, and statistical analysis of surface changes over time.
-
These datasets, produced by Geoscience Australia and Digital Earth Australia, provide valuable resources for environmental monitoring, resource management, and scientific research within Australia.

Australian 5M DEM
The Digital Elevation Model (DEM) 5 meter Grid of Australia derived from LiDAR model represents a National 5 meter (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 kilometers. … australia dem elevation elevation-topography ga geophysical -
DEM-H: Australian SRTM Hydrologically Enforced Digital Elevation Model
The Hydrologically Enforced Digital Elevation Model (DEM-H) was derived from the SRTM data acquired by NASA in February 2000. The model has been hydrologically conditioned and drainage enforced. The DEM-H captures flow paths based on SRTM elevations and mapped stream lines, and supports delineation of … australia dem elevation elevation-topography ga geophysical -
DEM-S: Australian Smoothed Digital Elevation Model
The Smoothed Digital Elevation Model (DEM-S) was derived from the SRTM data acquired by NASA in February 2000. DEM-S represents ground surface topography (excluding vegetation features) and has been smoothed to reduce noise and improve the representation of surface shape. An adaptive process applied more … australia dem elevation elevation-topography ga geophysical -
Preview National Intertidal Digital Elevation Model 25m 1.0.0
The National Intertidal Digital Elevation Model (NIDEM; Bishop-Taylor et al. 2018, 2019) is a continental-scale elevation dataset for Australia's exposed intertidal zone. NIDEM provides the first three-dimensional representation of Australia's intertidal sandy beaches and shores, tidal flats and rocky shores and reefs at 25 m … australia dem elevation-topography ga
