Bathymetry of the Australian Marine Parks

This dataset is a compilation product of all publicly available surveyed bathymetry within the Australian Marine Parks (AMPs, 2025 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 10/12/2025 and represents all public bathymetry data intersecting AMPs that could be located as of that date.PARK....................................................% COVERAGEAbrolhos...............................................56%Apollo*.................................................100% (63%)Arafura.................................................11%Argo-Rowley Terrace............................34%Arnhem.................................................

本数据集为澳大利亚海洋公园（Australian Marine Parks, AMPs，2025年边界）内所有公开可用的实测水深数据汇编产物，针对每个AMP整合为单一多分辨率合成数据集。
该数据由澳大利亚海洋地图项目（Seamap Australia）作为"我们的海洋公园"（Parks Australia）项目的一部分编制，项目获得澳大利亚政府资助，旨在提升对澳大利亚海洋公园不动产分类相关知识的认知。
本次水深数据汇编是生成地貌分类的第一步（衍生地貌测绘地图详见https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/40e9283b-d4ed-4176-8fe6-112b8697003f）。
水深数据整理自AusSeabed数据馆藏（https://portal.ga.gov.au/persona/marine）、西澳大利亚州水深门户（https://dot-wa.maps.arcgis.com/apps/webappviewer/index.html?id=d58dd77d85654783b5fc8c775953c69b）、澳大利亚海洋数据网络（https://portal.aodn.org.au/）及其他现有公共数据仓库。
针对每个AMP均生成了单一多分辨率水深镶嵌图及配套的多分辨率晕渲镶嵌图。
本数据集以面向制图区域的、叠加晕渲图的水深网络地图服务形式提供；针对每个AMP，可下载两类数据：(1) 水深数据；(2) 晕渲数据，均为GeoTIFF格式文件。
下表列出了本数据包涵盖的海洋公园及其水深数据覆盖率百分比。未在下表中列明的公园，其对应溯源数据源中无公开可获取的水深数据。本数据集最后更新于2025年12月10日，涵盖截至该日期可获取的所有与AMPs相交的公开水深数据。
