Eromanga grids contours

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis dataset is comprised of derived thickness grids and contours for the Bandanna and Eromanga Basins within Galilee subregion.\n\n\n\nThe dataset also contains annotation text and masks for the Eromanga basin.\n\n## **Purpose** \n\nThe annotation text is used for labeling contour values and the cartographic mask is used to clear unwanted features from report maps.\n\n## **Dataset History** \n\nBandanna data:\n\nBandanna_thk = DEM (GUID: ebcf6ca2-513a-4ec7-9323-73508c5d7b93) - Top_Bandanna(Steph Hostetler)\n\nThis GRID was produced using Arc Catalogue raster calculator tool\n\n\n\nEromanga data:\n\nEromanga_not_clipped_contour: derived from Grid (Eromanga_thickness_not_clipped)\n\nEromanga_thickness_not_clipped = DEM (GUID: ebcf6ca2-513a-4ec7-9323-73508c5d7b93) - \\*layer10 (ESRI GRD)_clp\\* \\[GUID: 11dcfa96-2a3e-402d-b6f2-1e90290842f7\\] This GRID was produced using Arc Catalogue raster calculator tool\n\n\n\nBandanna_contour: derived from the grid (Bandanna_thk) using topo to raster tool in ArcMap.\n\n\n\nAnnotation text and masks were created using the ArcGIS tool 'FeatureOutlineMasks'\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2015) Eromanga grids contours.
