<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The AHGFMappedStreams are derived from the AusHydro V2 Watercourse feature class. The features have been organised 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. MappedFlowSegment:corresponds to an existing blueline stream from AusHydro V2 Watercourses MappedArtificialFlowSegment: corresponds to a stream flow "connector" from AusHydro V2 Watercourses. These are additional stream segments that represent logical stream flow direction when compared to the AHGFNetworkStreams. MappedWaterAreaSegment: these are logical stream flow connectors through AHGFWaterbodies. All of these features participate in the connected stream flow topology.</SPAN></P></DIV></DIV></DIV>

The AHGFMappedStreams are derived from AusHydro V2 Watercourses feature class. As such, the natural water course layer consists of a linear network with a consistent topology that provide directional flow paths through the network for hydrological analysis. Aushydro V2 includes Geoscience Australia's national surface hydrology database which is a selection of features from the regional surface hydrology database, at a comparable 1:250,000 mapping density. Additional Regional features have been added where necessary to ensure important features such as flow paths are included in the Geofabric. This natural watercourse dataset consists of directional flow paths and provides a direct link to the flow paths derived from the DEM.

Selected set of Major Named Mapped Streams
Geoscience Australia has aggregated best available multiscale (1:25,000-1:250,000) jurisdictioanl datsets. As such where known each individual feature has been attributed with a relevant planimetric accuracy.
1) AusHydro V2 Surface Hydrology dataset is loaded into the Geofabric development GIS environment. 2) Feature classes from AusHydro V2 are recomposed into composited Geofabric hydrography dataset feature classes in the Geofabric Maintenance Geodatabase. 3)These are assigned unique Hydro-IDs using ESRI ArcHydro for Surface Water. 4) Feature classes from the Geofabric Maintenance Geodatabase hydrography dataset are extracted and reassigned to the Geofabric Surface Cartography Feature Dataset within the Geofabric Surface Cartography Geodatabase.
Aushydro V2 includes Geoscience Australia's national surface hydrology database which is a selection of features from the regional surface hydrology database, at a comparable 1:250,000 mapping density. The regional surface hydrology database is aggregated from multiple jurisdictional sources. The scale of the data ranges from 1:25,000 to 1: 250,000 across the continent (http://www.ga.gov.au/scientific-topics/water/national-surface-water-information). Additional regional features have been added where necessary to ensure important features such as flow paths are included in the Geofabric. As input data is multiscale, and the 1 second DEM approximates a 30m grid cell size, the Geofabric attributes a nominal scale of 1:100,000 across V3 products.
