Description
AusBathyTopo (Torres Strait) 30m 2023 is a regional-scale depth and elevation dataset compiled into a 30-meter resolution Digital Elevation Model (DEM). The dataset was compiled by the Australian Ocean Data Network from multiple sources, including multibeam surveys, LiDAR, and satellite data, and was last updated in 2026. It covers the Torres Strait area, bounded by Australia, Indonesia, and Papua New Guinea, at the northern end of the Great Barrier Reef.
Use Cases
Marine habitat mapping based on the 30-meter resolution bathymetry and topography grid.
Simulating water mixing for whole-of-Great Barrier Reef scale hydrodynamic models based on the depth data.
Analyzing the complex continental slope canyons and Fly River delta deposits based on the compiled multibeam survey data.
Supporting environmental management and safe navigation planning for the Torres Strait reef and shoal system.
Strengths
High-resolution 30-meter grid for detailed spatial analysis.
Compiled from multiple authoritative sources, including deep and shallow-water multibeam surveys, airborne LiDAR, and satellite-derived bathymetry.
Covers a vital ecological region at the northern end of the Great Barrier Reef.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
The dataset is explicitly not to be used for navigational purposes, limiting its application scope.
Row count and file size are unknown, which may limit suitability assessment.
Provenance
Source
Australian Ocean Data Network, utilizing data from the CSIRO Marine National Facility and other surveys.
Collection Method
Compilation and editing of point cloud data from multibeam surveys, LiDAR, and satellite sources into a consistent WGS84/MSL DEM.
