Australian National Aquatic Ecosystem (ANAE) classification for the Murray Darling Basin - Watercourses (2017)

ANAE_Watercourses a compilation of 1:50,000 to 1:100,000 jurisdiction stream line mapping pruned to those stream segments that align with the 1:250,000 Geofabric v2 catographic stream line mapping (Bureau of Meteorology 2012). Gaps in jurisdiction mapping (missing stream segments) were in-filled from the Geofabric. The result is a representation of the Murray-Darling basin stream network equivalent to the Geofabric cartography but uses more accurate mapping for each river segment. The higher accuracy gave better alignment of stream mapping against other ANAE attribute data layers for vegetation, soils and landform.Source data sets are listed in the DataSources table in the MDB_ANAE geodatabase. Data sources range in scale from 1:25,000 to 1:250,000.Aninterim application of the Australian National Aquatic Ecosystem (ANAE) classification framework has been applied to river segments, ANAE attributes and the final riverine classification typology based on landform and water regime are included in the data table.CC - Attribution (CC BY) This data has been licensed under the Creative Commons Attribution 3.0 Australia Licence.

Victoria Victoria maintains an inventory of wetlands (WETLAND_CURRENT) which is designed for use in Victorian wetland projects and is subject to ongoing validation and updates. WETLAND_CURRENT can be obtained from the Department of Environment and Primary Industries (see http://www.depi.vic.gov.au/forestry-and-land-use/maps-imagery-and-data for further details). For lacustrine and palustrine aquatic ecosystems, the MDB_ANAE geodatabase is more suited to wetland projects involving other jurisdictions. While much of the data for lacustrine and palustrine wetlands was sourced from WETLAND_CURRENT, there may be some inconsistencies between MDB_ANAE geodatabase and WETLAND_CURRENT. The two datasets can be linked through the AltSrcID (MDB_ANAE geodatabase) and Wetland_No (WETLAND_CURRENT data set) fields.SA Due to the Basin-wide nature of this dataset, accuracy of final classes has not been ground truthed comprehensively, which could impact results of any analysis using this data. Therefore it is imperative that this dataset is assessed as to fitness for use in any application and decisions made about further levels of validation required. Significant care should be taken if information derived from this dataset is to guide decision making, form binding agreements regarding target setting, compliance of any form, or monitoring of achievements, this includes for the purpose of summarising areas of wetland types.
