Physiographic Regions of Australia

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nThe Physiographic Regions of Australia (Pain, Gregory, Wilson and McKenzie 2011) are a modification of those compiled by Jennings and Mabbutt (1977), and are based on a visual interpretation of landforms as expressed on the Shuttle Radar Terrain Mission (SRTM) digital elevation model (DEM). Apart from its descriptive role, a map of physiographic regions provides a regional system of reference for geomorphological and related physical geographical accounts. Through the groupings of physiographic regional characteristics at different levels, the action of underlying controls, for instance geologic or climatic, may be made apparent. Further, the map can provide a regional basis for an understanding of land characteristics that are dependent upon landforms, for example the distribution of soils or natural vegetation.

Lines were drawn onto the maps (with 4B pencils), by comparing the original lines of Jennings and Mabbutt and the landform patterns that could be seen in the SRTM hill shaded data. State and territory agencies provided corrections and updates to this initial line work, which were also digitized. Line work in Western Australia has been altered significantly, so that it approximates to an aggregation of the state soil landscape survey boundaries.\n\n\n\nThe 1:100 000 Geoscience Australia Coastline (2004) has been used, rather than state specific line work, to provide national consistency. Attributes within the accompanying database were attached to the polygons via the region_id.\n\n## **Dataset Citation** \n\nCSIRO (2011) Physiographic Regions of Australia.

**摘要**

本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交版本呈现。

澳大利亚地貌区域（Physiographic Regions of Australia，Pain、Gregory、Wilson与McKenzie，2011年）是对Jennings与Mabbutt（1977年）编制的地貌区域的修订，其基于对航天飞机雷达地形测绘任务（Shuttle Radar Terrain Mission, SRTM）数字高程模型（digital elevation model, DEM）所呈现的地貌的目视解译。除具备描述性功能外，地貌区域地图可为地貌学及相关自然地理研究提供区域性参考体系。通过对不同层级的地貌区域特征进行归类，地质、气候等下伏控制因素的作用可得以明晰。此外，该地图可为理解依赖于地貌的土地特征（如土壤或天然植被的分布）提供区域性基础。

**数据集历史**

澳大利亚地貌区域的线划要素源自1:100万高程地图（SRTM 90米分辨率）的数字化或扫描处理，该地图采用西北方向光照晕渲。研究人员通过对比Jennings与Mabbutt的原始线划以及SRTM晕渲地形数据中可见的地貌格局，使用4B铅笔在地图上绘制了线划成果。各州与领地机构对该初始线划成果提供了修正与更新，这些修正与更新内容同样进行了数字化处理。西澳大利亚州的线划成果经过大幅调整，以近似该州土壤景观调查边界的聚合结果。

为保障全国数据的一致性，本次采用了澳大利亚地质科学局（Geoscience Australia）2004年发布的1:10万海岸线数据，而非各州专属的线划成果。配套数据库中的属性通过region_id字段关联至各多边形要素。
