The 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.
This shapefile shows the extent of the Grafton-Piora bedrock in the CLM bioregion.
The shapefile is based on the digital 1:250000 surface geological map (see lineage) obtained from the Clarence-Moreton SEEBASE project in NSW. This polygon shapefile has been created from a preliminary dataset provided by the NSW Geological Survey. The original shapefile consisted of multiple polygons that have been separated for example where alluvia overlie this bedrock unit. The polygons have been dissolved to create a single shapefile that shows the extent of the unit at the surface and in the subsurface.
