Geomorphic Features 2006

The data set provides outlines for the maximum extent of geomorphic units for Australia's Exclusive Economic Zone, including the offshore island territories, but not the Australian Antarctic Territory. These data were compiled as part of Geoscience Australia's integrated digital information system to provide improved accessibility and knowledge relating to the environmental management of Australia's oceans resources. The geomorphic units are to be used as surrogates for benthic habitats and can be best applied to the construction of bioregionalisations of the seabed. The data set also includes the name of units in the attribute table, where known, the source(s) of the names, feature codes and province codes as well as the area and perimeter of each unit. The data are accompanied by Geoscience Australia Record 2003/30. Updated October 2006.本数据集涵盖澳大利亚专属经济区（Exclusive Economic Zone，包含离岸岛屿领地，但不含澳大利亚南极领地）内所有地貌单元（geomorphic units）的最大范围轮廓。本数据集作为澳大利亚地质调查局（Geoscience Australia）集成数字信息系统的组成部分编制而成，旨在提升澳大利亚海洋资源环境管理相关信息的可获取性与认知水平。该地貌单元可作为底栖生境（benthic habitats）的替代指标，最适用于海底生物区域区划的构建工作。本数据集的属性表中还包含已知地貌单元的名称、名称来源、要素编码、区域编码，以及各单元的面积与周长信息。本数据集附带澳大利亚地质调查局2003/30号报告，并于2006年10月完成更新。
