This dataset represents the State Government's key Pre-European Settlement floristic vegetation mapping layer for the SA agricultural region. It identifies floristic composition and general structural information (referred to as vegetation communities) of areas of native vegetation thought to have been found at a particular location in the South Australia agricultural region prior to European settlement (1836).

This data set shows designated and actual irrigation areas in Australia compiled by the National Land Use Mapping Project of the National Land and Water Resources Audit to assist in the identification of irrigation areas in Australia. Additional data custodians include Agriculture WA, Queensland Department of Natural Resources and Mines, Murray-Darling Basin Commission, New South Wales Department of Land and Water Conservation and Tasmanian Department of Primary Industries, Water and Environment Designated irrigation areas indicate areas with administratively defined boundaries which have associated rights and obligations pertaining to use of water for irrigation. The precise meaning of the term designated irrigation area varies from region to region. aActual irrigation areasa indicate areas with observationally defined boundaries within which irrigation is practised. The boundaries have been supplied by various agencies and cover the more important irrigation areas in Australia. Users of this data set should be aware that there are irrigated areas outside the designated and actual areas shown and that there are non-irrigated areas inside them. This is particularly true of Tasmania and the Murray-Darling Basin.The data set is available in both vector and raster formats. The raster data set can be used as a companion to the 1996/97 Land Use of Australia data set which is also in raster format. Both data sets have the same coordinate system, boundary coordinates and cell size so that they can easily be overlaid. Users may find, however, that some cells are classified as irrigated by the Australian Irrigation Areas data set and as non-agricultural land by the 1996/97 Land Use of Australia data set.The Version 1a data set may be of use to researchers and policy makers in need of national, regional or local scale irrigation data, though the scale of the source material is highly variable and completness of coverage is poor in some regions. See [further metadata](http://data.daff.gov.au/anrdl/metadata_files/pa_aia__r9ab __00211a02.xml) for more detail. Lineage: The data set was constructed in vector format by appending irrigation area boundary data sets supplied by various agencies. The component data sets are listed below. One of the component data sets which was supplied as separate tiles in ArcView shapefile format was assembled into a single shapefile data set in ArcView 3.1. All other processing was carried out in ARC/INFO 7.2.1 under SunOS using double precision coordinates. For all operations in which processing used a fuzzy tolerance, the value specified was 0.00001 degrees (about 1 m). The raster form of the data set was made from the vector form. 1) Ord River Scheme, Stage 1, irrigation area boundaries. This data set was supplied by Agriculture WA in ArcView shapefile format.2) Boundary of Gazetted Irrigation Areas in Queensland. This data set was supplied by the Queensland Department of Natural Resources and Mines in ARC/INFO export file format. It shows designated irrigation areas. The coordinate datum is not known with certainty and was assumed to be the Australian Geodetic Datum 1984.3) Northern Murray-Darling Basin irrigation area boundaries. This data set was supplied by the Murray-Darling Basin Commission in ARC/INFO export file format. It shows actual irrigation areas, based on interpretation of coarse scale imagery derived from Landsat TM images. The data set comprises 11 polygons. Of these, five have not been retained in the national data set because they largely coincide with the much higher resolution polygons of the Northern New South Wales Cotton Development data set. A sixth has not been retained because it proves to be almost entirely covered by a national park and a perennial lake. One of the polygons that was retained was edited to give precedence to a higher resolution polygon in the Boundary of Gazetted Irrigation Areas in Queensland data set which it partly overlies.4) Northern New South Wales Cotton

This dataset categorises the 2020 native vegetation extent mapping by vegetation complexes for the Swan Coastal Plain and the South West Forest Region of Western Australia.

This dataset categorises the 2020 native vegetation extent mapping by pre-European state-wide vegetation mapping of Western Australia.

The South Australian Land Cover Layers 1987- 2015 spatial land cover datasets for 6 time periods (1987-1990, 1990-1995, 1995-2000, 2000-2005, 2005-2010 and 2010-2015). This dataset can be used to inform spatial and temporal (5 year) summaries of the described land cover types for SA. The capture method and general nature of the classes are most useful for landscape and regional scale assessment.

The NVIS vegetation attributes contain information on vegetation structure (growth form, height and cover) and floristics (genus and species) as documented in the Australian Vegetation Attribute Manual Version 7.0 (NVIS Technical Working Group, 2017). The NVIS detailed Level 1-6 vegetation descriptions make up theNVIS Information Hierarchy andare used to assign the Major Vegetation Groups and Major Vegetation Subgroups classifications. The hierarchy is based on structural and floristic information including dominant genus, growth form, height and cover and are preferably collected at the Level 6 Sub-Association (sub-stratum) level. For many reasons including different scales and classification methods, not all data is collected at this level of detail. Currently there are over 19,500 distinct NVIS vegetation descriptions in the NVIS database. For more information refer to the Australian Vegetation Attribute Manual.These detailed vector data products may be used at a regional scale and allow for more complex analyses when joined with the associated Lookup Table of Flat File. They are available in Present (Extant) and Estimated Pre-1750 (pre-European - where available) themes. Data is available under CC BY. It is recommended the datasets be used alongside the Key Layers to better understand the source data attributes such as differing scales, age of data etc.For this update, Version 7.0, the extant datasets for Queensland, Australian Capital Territory, New South Wales and Tasmania have been updated. An automated, data-driven procedure, followed by thorough manual checks, was undertaken to make any necessary updates to MVG/MVS assignments for Australian Capital Territory, New South Wales and Tasmania. Conversely, Queensland directly provided the MVG/MVS assignments for the state.This dataset is not comparable with earlier versions of NVIS.Reference: NVIS Technical Working Group (2017) Australian Vegetation Attribute Manual: National Vegetation Information System, Version 7.0.

For complex analyses and to extract maximum information from NVIS spatial data, this LUT can also be linked to NVISDSC2-6. It is recommended that users refer to the Australian Vegetation Attribute Manual V7.0 for understanding of the NVIS hierarchy (Level 1-6 descriptions) -https://www.dcceew.gov.au/environment/land/publications/australian-vegetation-attribute-manual-version-7.Once this table has been joined, a simple display option is to use the field "NVIS7_0_LUT_AUST_DETAIL.MVG_NAME" (or MVS_NAME if preferred) which includes the names of the NVIS Major Vegetation Groups (MVGs).A legend or 'shadeset' for the MVGs and MVSs can be found packaged with the detailed vector data: NVIS7_0_AUST_EXT_[STATE] and NVIS7_0_AUST_PRE_[STATE].Use the field
