Description
A 30-meter resolution Digital Elevation Model (DEM) compiled in 2023 integrates depth and elevation data for the Torres Strait region. The dataset, produced by the Australian Ocean Data Network, combines multibeam surveys, airborne LiDAR bathymetry, satellite-derived bathymetry, and the National Intertidal Digital Elevation Model (NIDEM). It is intended for marine habitat mapping and hydrodynamic modeling, but is not for navigational use.
Use Cases
Marine habitat mapping based on integrated bathymetry and elevation data.
Simulating water mixing for hydrodynamic models based on the regional-scale depth model.
Analyzing continental slope canyons and delta deposits based on multibeam survey data.
Environmental management planning for reef and shoal systems based on bathymetry mapping.
Strengths
Integrates data from multiple sources including multibeam surveys, airborne LiDAR, and satellite-derived bathymetry.
Provides a 30-meter resolution grid for detailed regional analysis.
Covers the Torres Strait area, bounded by Australia, Indonesia, and Papua New Guinea.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
The dataset is not to be used for navigational purposes.
Provenance
Source
Australian Ocean Data Network
Collection Method
Compiled from multibeam surveys, airborne LiDAR bathymetry, satellite-derived bathymetry, and the NIDEM model.
