vector digital data
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The AHGFNetworkStreams are derived from the ANUDEM (version 5.3.0 3 November 2016) derived raster streams, and vectorised to be usable in vector line feature format. They are initially informed and modified by the coincident locations of AusHydro V2 Watercourse feature class. The features have been organized into specific Feature Class subtypes based upon both the inputs from the AusHydro V2 Watercourse feature class and their behaviour within the AHGF stream network relationships. NetworkFlowSegment:corresponds to an existing blueline stream from AusHydro Watercourses NetworkArtificialFlowSegment: corresponds to a stream flow "connector" from AusHydro V2 Watercourses. These are additional stream segments that represent logcial stream flow direction when compared to the AHGFMappedStreams. NetworkWaterAreaSegment: these are logical stream flow connectors through AHGFWaterbodies. All of these features participate in the connected stream flow topology.</SPAN></P></DIV></DIV></DIV>
Represents the stream network based on the 1 second DEM, with streamflow direction, and related the AHGFCatchment boundaries. The Geofabric Surface Network is intended to be used in stream flow tracing operations, and provides a spatial framework for analysis and assessment of streams and their catchments.

Vector lines derived from a regular 1 second grid delineating a fully connected and directed stream network for Australia. The network was derived by tracing the surface flow pathways coded by a multi-flow extension of the SRTM 1 second Flow Direction Grid Version 3.1, associated with the 1 SEC SRTM DEM-S. The stream network represents the AusHydro V2 watercourse line features, generalised to the 1 second DEM grid resolution consistent with the flow pathways defined in the flow direction grid. It adds DEM connectors where there are breaks in the AusHydro V2 Watercourse lines to provide a fully connected network suitable for network tracing and other analytical uses. This layer also relates to the AHGFCatchments through a shared segment identifier. The sub-catchment areas draining to each of the segments (links) in this layer form the lowest level sub-division of the catchments.
