Bathymetry of the Australian Marine Parks
This dataset is a compilation product of all publicly available surveyed bathymetry within the Australian Marine Parks (AMPs, 2023 boundaries), merged into a single multi-resolution composite per AMP. The data was compiled by Seamap Australia as part of an Our Marine Parks (Parks Australia) project with funding from the Australian Government to improve knowledge relating to classification of the Australian Marine Parks real estate. This compilation of bathymetry data was the first step in generating geomorphometry classifications (see https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/40e9283b-d4ed-4176-8fe6-112b8697003f for derived geomorphometry maps).
Bathymetry data was collated from AusSeabed data holdings ( https://portal.ga.gov.au/persona/marine), the WA Bathymetry Portal ( https://dot-wa.maps.arcgis.com/apps/webappviewer/index.html?id=d58dd77d85654783b5fc8c775953c69b), the Australian Ocean Data Network ( https://portal.aodn.org.au/) and other existing public data repositories. A single multi-resolution bathymetry mosaic, and associated multi-resolution hillshade mosaic, was generated for each AMP.
Data is supplied as a single Web Map Service of bathymetry on hillshade for the mapped regions. Data is available for download as (1) bathymetry, and (2) hillshade, Geotiff files for each AMP.
The table below indicates the Parks included in this data package, and the percent coverage of bathymetric data for each. Parks not expressly listed below had no publicly accessible bathymetry data available from the sources listed in the 'lineage' section below. This dataset was last updated on 17/04/2024 and represents all public bathymetry data intersecting AMPs that could be located as of that date.

- Statement
- Bathymetry mosaics for each Australian Marine Park were generated by collating all available bathymetry survey data intersecting AMPs, at the highest available gridded resolution. Data was mosaiced into a single multi-resolution raster product for each AMP using the ArcMap (v 10.8.1) tool RASTER CATALOG TO RASTER DATASET (options: Mosaic Operator: FIRST; Resampling Method: BILINEAR). The MOSAIC TO NEW RASTER tool was also explored, but results were unpredictable and the use of Raster Catalogs produced repeatable outcomes. Datasets were organised in the input Raster Catalogs such that the highest priority (aka mosaiced last) was assigned to: (1) highest resolution; and (2) most recent data (where resolution was identical. This meant that, where bathymetry datasets overlapped in the mosaic, only the first (higher resolution) data was retained for each area. In cases where input data had clear artefacts or errors, these areas were clipped out, or the input Geotiff was deprioritised in the mosaic. Hillshade (z-factor = 5m, azimuth = 315°, altitude = 45°) was computed for each bathymetry dataset and mosaiced into a second multi-resolution raster product for each AMP using the process described above. This enabled preservation of the highest-resolution shading detail available for each AMP. Bathymetry and hillshade mosaics were clipped to the boundaries of AMPs. Mosaic datasets for each AMP were then exported as Geotiffs with lossless compression for subsequent processing.
