Australian Irrigation Areas (Raster), Version 1A, National Land and Water Resources Audit

\n\nThis data set shows designated and actual irrigation areas in Australia\ncompiled by the National Land Use Mapping Project of the National Land and\nWater Resources Audit to assist in the identification of irrigation areas in\nAustralia. Additional data custodians include Agriculture WA, Queensland\nDepartment of Natural Resources and Mines, Murray-Darling Basin Commission,\nNew South Wales Department of Land and Water Conservation and Tasmanian\nDepartment of Primary Industries, Water and Environment.aDesignated irrigation\nareasa indicate areas with administratively defined boundaries which have\nassociated rights and obligations pertaining to use of water for irrigation.\nThe precise meaning of the term adesignated irrigation areaa varies from\nregion to region. aActual irrigation areasa indicate areas with\nobservationally defined boundaries within which irrigation is practised. The\nboundaries have been supplied by various agencies and cover the more important\nirrigation areas in Australia. Users of this data set should be aware that\nthere are irrigated areas outside the designated and actual areas shown and\nthat there are non-irrigated areas inside them. This is particularly true of\nTasmania and the Murray-Darling Basin.The data set is available in both vector\nand raster formats. The raster data set can be used as a companion to the\n1996/97 Land Use of Australia data set which is also in raster format. Both\ndata sets have the same coordinate system, boundary coordinates and cell size\nso that they can easily be overlaid. Users may find, however, that some cells\nare classified as irrigated by the Australian Irrigation Areas data set and as\nnon-agricultural land by the 1996/97 Land Use of Australia data set.The\nVersion 1a data set may be of use to researchers and policy makers in need of\nnational, regional or local scale irrigation data, though the scale of the\nsource material is highly variable and completedness of coverage is poor in\nsome regions.\n\nSee [further metadata](http://data.daff.gov.au/anrdl/metadata_files/pa_aia__r9ab\n__00211a01.xml) for more detail.\n\n
