Basement Relief Raster Image of Australian Onshore and Offshore Sedimentary Basins - ARC

## **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\nInterpretation of the extent of the Warburton Basin using basement relief imagery of onshore and offshore sedimentary basins.\n\n## **Purpose** \n\nThe data file is used to indicate the location and understood extent of the Warburton Basin.\n\n## **Dataset History** \n\nThe Warburton Basin outline interpretation was extracted from the file sedbasdd.shp, which was obtained from GA. As many basins onlap, basin outlines are subdivided according to how many basins onlap the basin in quation. Therefore a selection of all outlines classified as Warburton Basin from the categories B1, B2, B3 and B4 was used to obtain the entire basin outline. These outlines were then combined to form a single outline for the Warburton Basin.\n\n## **Dataset Citation** \n\nSA Department of Environment, Water and Natural Resources (2015) Basement Relief Raster Image of Australian Onshore and Offshore Sedimentary Basins - ARC.

## **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），此处按原始提交内容原样呈现。

基于陆上与近海沉积盆地的基底起伏影像，对沃伯顿盆地（Warburton Basin）的分布范围进行解译。

## **目的**

本数据文件用于标注沃伯顿盆地的位置与已明确的分布范围。

## **数据集历史**

沃伯顿盆地轮廓解译数据提取自从GA获取的sedbasdd.shp文件。由于存在多个盆地超覆现象，盆地轮廓将根据所讨论盆地被其他盆地超覆的数量进行细分。因此，从B1、B2、B3和B4类别中筛选出所有归类为沃伯顿盆地的轮廓，以获取完整的盆地轮廓，随后将这些轮廓合并为沃伯顿盆地的单一整体轮廓。
