Basement Relief Raster Image of Australian Onshore and Offshore Sedimentary Basins (National Geoscience Dataset) - PED

## **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. Original extraction comes from sedbasdd.shp.\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 (National Geoscience Dataset) - PED.
