Canal Area: An artificial open channel which provides the supply, distribution or removal of water for irrigation purposes, or for a significant infrastructure function (such as salt interception, land reclamation, or drainage). Flat: Land which is so saturated with water that it is not suitable for agricultural or pastoral use and presents a barrier to free passage or Low lying land usually adjacent to lakes or watercourses, which is regularly covered with flood water for short periods. Foreshore Flat: That part of the seabed or estuarine areas, between mean high water and the line of lowest astronomical tide. Pondage Area: Shallow beds, usually segmented by constructed walls, for the use of aquaculture or a flat area, usually segmented, used for the commercial production of salt by evaporation and shallow beds, usually segmented by constructed walls, for the treatment of sewage or other wastes. Rapid Area: An area of broken, fast flowing water in a watercourse, where the slope of the bed increases (but without a prominent break of slope which might result in a waterfall), or where a gently dipping bar of harder rock outcrops.</SPAN></P></DIV></DIV></DIV> We request attribution as © Commonwealth of Australia (Bureau of Meteorology) 2022 Environmental Prediction Services, Water Analysis Bureau of Meteorology, Community Services Group GPO Box 378 CANBERRA ACT 2601 AU ahgf@bom.gov.au Foreshore Flat Drains Flat Canals Rapid Area Watercourse Area Pondage Area foreshore flat drains flat canals rapid area watercourse area pondage area cartography Licenced for use under Creative Commons Australia Attribution <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Creative Commons Attribution</SPAN><SPAN> V4.0 (CC BY 4.0)</SPAN></P></DIV></DIV></DIV> ESRI ArcCatalog 10.3.1.4959 publication date 113.00706 153.6052 -43.589989 -8.933329 A composite set of area features that provide additional hydrological information, but do not participate in the stream network relationships. 1 113.007060 153.628392 -10.053490 -43.589976 Hydrology area polygons other than waterbodies 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. 0 60419 AHGFHydroArea Feature Class 38467 An artificial open channel which provides the supply, distribution or removal of water for irrigation purposes, or for a significant infrastructure function (such as salt interception, land reclamation, or drainage FSource Name of agency that originally captured the spatial object.
