**摘要**

本数据集由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交状态呈现。未提供原始元数据，故由生物区域评估计划基于数据采集时的已知信息完成元数据编制。

本坡度数据源自由澳大利亚地质调查局（Geoscience Australia, GA）、澳大利亚气象局（Bureau of Meteorology, BoM）、澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）及澳大利亚国立大学（Australian National University, ANU）依据国家高程数据框架开发的1弧秒航天飞机雷达地形测绘任务（Shuttle Radar Topography Mission, SRTM）全球高程数据集（Digital Elevation Model, DEM），相关研究成果见Gallant等人2011年发表的文献。坡度数据用于表征地形起伏变化特征。

用于表达地表相对于水平面的坡度。

**数据集用途**

坡度数据用于表征地形起伏变化特征。

**数据集沿革**

本坡度数据基于1弧秒数字高程模型（Digital Elevation Model, DEM），通过ArcGIS软件工具生成。
