Description
A 2023 regional-scale 30-meter resolution Digital Elevation Model (DEM) compiled from multiple sources for the Torres Strait region. The dataset, produced by Geoscience Australia, integrates deep-water multibeam surveys, shallow-water multibeam data, airborne LiDAR bathymetry, satellite-derived bathymetry, and the National Intertidal Digital Elevation Model (NIDEM). It provides a fundamental grid for marine habitat mapping and hydrodynamic modeling within the Great Barrier Reef ecosystem.
Use Cases
Marine habitat mapping based on the integrated bathymetry and topography data.
Simulating water mixing for hydrodynamic models based on the whole-of-Great Barrier Reef scale DEM.
Supporting safe shipping navigation planning based on the detailed mapping of the extensive reef and shoal system.
Improving environmental management strategies based on the compiled depth data for the Torres Strait region.
Strengths
30-meter spatial resolution provides detailed topographic and bathymetric information.
Integrates data from multiple advanced sources, including multibeam surveys, LiDAR, and satellite-derived bathymetry.
Covers a strategically vital region bounded by Australia, Indonesia, and Papua New Guinea.
Source data were extensively edited as point clouds to remove noise and given consistent datums.
Limitations
Dataset is not to be used for navigational purposes, limiting its application for real-time maritime safety.
Row count and specific column-level documentation are absent, which may limit suitability assessment.
Description metadata is limited; actual data quality and completeness require manual inspection after download.
