Abstract
The dataset was derived by the Bioregional Assessment Programme from Geodata: 9 second DEM and the National surface water sites Hydstra. The source datasets for this dataset are identified in the Lineage field of the metadata statement. The history field in the metadata describes the processes undertaken to produce this dataset.
Contributing areas (residual catchments) for selected stream gauges in the Galilee subregion.
Dataset History
Gauge locations were snapped to GA DEM 9s derived flow accumulation lines representing their respective rivers. ArcGIS WATERSHED tool was run on the GA 9s flow direction raster using the snapped gauge locations as pour points to produce catchments areas for the selected gauges. Output rasters were converted to vector polygon shapefiles to delineate catchment boundaries for individual gauges.
