Land tenure of Australia 2015-16, Tenure data caveat

Abstract This layer shows where and how data gaps were filled for the Land tenure of Australia 2015–16. The data caveats highlight known uncertainties in land tenure for 2015-16 when reporting land tenure change in the Land tenure of Australia 2010-11 to 2020-21. The data was produced by the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) within the Australian Government Department of Agriculture, Fisheries and Forestry as part of the Australian Collaborative Land Use and Management Program (ACLUMP). For more information see the dataset metadata at [DOI: 10.25814/89rx-zs30]. [Land tenure of Australia 2015-16, Data caveat] Currency Date modified: 31 October 2024 Publication Date: 31 October 2024 Modification frequency: As needed Data Extent The following spatial extent is provided in the Geocentric Datum of Australia (GDA94). Coordinate reference: WGS84 / Mercator Auxiliary Sphere Spatial Extent North: -9.995 South: -44.005 East: 154.004 West: 112.505 Source Information Data, Metadata, Maps and Interactive views are available from [Land tenure of Australia 2010–11 to 2020–21] [Land tenure of Australia 2010–11 to 2020–21 – Descriptive metadata] The data was obtained from the Department of Agriculture, Fisheries and Forestry - Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES). ABARES is providing this data to the public under a [Creative Commons Attribution 4.0 license]. Lineage Statement The data caveat shows where data voids for 2015–16 were filled by data from recent years, spatial filtering (despeckling), stock routes or Tenure of Australia's forests (2018). For more information see the [dataset metadata]. Note: The Digital Atlas of Australia downloaded and created a copy of the source data in February 2025 that was suitable to be hosted through ArcGIS Image Server & Image Dedicated. A copy of the raster dataset was created with RGB fields as a colour map with Geoprocessing tools in ArcGIS Pro, and the raster dataset was re-projected from 1994 Australia Albers to WGS 1984 Web Mercator (Auxiliary Sphere). Additionally, records that have a -1 value have been removed to improve web mapping performance. This Web Mapping Service is for display purposes only. It is in Web Mercator projection and not suitable for deriving area statistics. For any analyses use the [original dataset] published in Albers projection.
