The AHGFCanalLines are derived from AusHydro V2 CanalLine feature class. 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.

Canal lines
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.
