Northern Australia's continental shelf and adjacent slope, spanning over 1500 km, are represented in a 30-meter resolution Digital Elevation Model. The dataset integrates shallow- and deep-water multibeam surveys, airborne LiDAR bathymetry, satellite-derived bathymetry, and an Intertidal Elevation Model. Compiled by Geoscience Australia and the Australian Hydrographic Office, the data were edited as point clouds and standardized to WGS84 and MSL datums.
Use Cases
- Modeling safe shipping routes based on detailed seafloor depth data
- Analyzing coral reef and sand cay distribution based on shallow bathymetry
- Mapping drowned ancient river valleys and slope canyons based on continental shelf topography
- Improving environmental management plans based on intertidal zone elevation data
Strengths
- High-resolution 30-meter grid covering a region over 1500 km in length
- Integrates multiple data sources including multibeam surveys, LiDAR, and satellite-derived bathymetry
- Data were extensively edited as point clouds and given consistent WGS84 and MSL datums
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count and dataset size are unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the specific Northern Australia region
