Abstract
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-Rapville bedrock in the CLM bioregion.
Dataset History
The shapefile is derived from a preliminary geological map provided by the NSW Geological Survey that shows the extent of this formation in NSW (see lineage). This polygon shapefile has been created from a preliminary datasets 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. This polygons have been dissolved to create a single shapefile that shows the extent of the unit at the surface and in the subsurface.
