HUN Greta And Goulburn At Hunter Junction catchments v01

Abstract

The dataset was derived by the Bioregional Assessment Programme from the GEODATA 9 second DEM and D8: Digital Elevation Model Version 3 and Flow Direction Grid 2008 dataset. The source dataset is 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.

Contributing catchments for selected locations in the Hunter subregion. Generated from the Geoscience Austraila 9 second flow direction grid. Catchments exist as both a grid and a shapefile version. The pour points used in the delineation of these catchments are included in the dataset.

Dataset History

Selected locations were used as pour points to generate contributing catchment areas from the GA 9 second flow direction raster. The catchment delineation was achieved using the ArcGIS 10.1 Spatial Analyst WATERSHED tool from the Hydrology toolbox. Resultant watershed raster was also converted to a shapefile (no generalisation).
