<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The AGHFCatchments are the lowest level stream flow catchments based upon the inputs from ANUDEM derived raster streams. The catchment boundaries are based upon a single AHGFNetworkStreamSegment extent over 1 SEC SRTM DEM-S grid. These catchments form the basis of aggregated catchment boundaries, either by Contracted Nodes or by Pfafstetter Id Levels.</SPAN></P></DIV></DIV></DIV>

ESRI ArcCatalog 10.3.1.4959
The geometry of this product is largely derived from ANUDEM (version 5.3.0 3 November 2016) and ATAD version 173 / ANUCatchment Toolkit version 2.3.6. These polygons are converted from a regular 1 second grid delineating the National Catchment Boundaries (NCB) for the Australian continent. The NCBs delineate hierarchically-nested catchments derived using an automated drainage analysis procedure based on a multi-flow extension of the flow direction grid associated with the 1 SEC SRTM DEM-S where possible. At lower levels, the Level 2 units are sub-divided into successively finer sub-catchments using a modified version of the Pfafstetter procedure (Verdin, K. L. and Verdin, J. P. (1999) A topological system for delineation and codification of the Earth's river basins. Journal of Hydrology, 218(1-2), 1-12). This layer delineates the lowest level catchment units being the sub-catchments draining directly to a stream segment in the ANUDEM raster stream layer (ANUDEM streams product name and ANZLIC identifier to be inserted) or, where there are no ANUDEM streams, the 1 second drainage basin. The higher level catchment membership of each of these sub-catchments is derived from its NCB code.
