Land use of Australia, Version 4 2005/2006 (September 2010 release, BRS)

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

The Land Use of Australia, Version 4, 2005-06, is a land use map of Australia for the year 2005-06. The non-agricultural land uses are drawn from existing digital maps covering six themes: topographic features, catchment scale land use, protected areas, world heritage areas, tenure and forest cover. Time series data at relatively high temporal resolution are available for the protected areas and forest themes. Only intensive land uses (e.g. built-up areas, mining) and plantation forestry were drawn from the catchment scale land use data.

The types of agricultural land uses to be mapped and their abundances were based on the 2005-06 agricultural census data collected by the Australian Bureau of Statistics (ABS); the spatial distribution of the agricultural land uses was modelled and has largely been determined using Advanced Very High Resolution Radiometer (AVHRR) satellite imagery with training data. Irrigation status has also been mapped. Existing digital maps also contributed to the classification of grazing land as native or modified pastures. The maps are supplied as ArcInfo (Trademark) grids with geographic coordinates referred to GDA94 and 0.01 degree cell size.

The distribution and abundance of most of the agricultural land uses is described by a set of floating point grids serving as probability surfaces for specific agricultural land uses. There is also a single integer grid serving as a categorical summary land use map, which has a value attribute table (VAT) with columns defining the mapped agricultural commodity groups, their irrigation status and the land use according to the Australian Land Use and Management Classification (ALUMC), Version 6 (http://www.daff.gov.au - search site for ALUM).

Prospective users of the data should note that caveats and additional metadata are included in a document entitled 'User Guide and Caveats: Land Use of Australia, Version 4, 2005-06' (ABARES, 2010) and that the Version 4 map differs significantly from the Version 3 maps.

Dataset History

Lineage

Catchment scale mapping is produced by combining land tenure and other types of land use information, fine-scale satellite data and information collected in the field. Mapping from many State and Territory agencies are combined and gridded at 50m Positional Accuracy The scale of the source data varies greatly. See individual landuse mapping dataset metadata for specific measures of accuracy. Attribute Accuracy The methods for mapping and classifying land use adhere to the standards outlined in the document ""Land Use Mapping at Catchment Scale - Principles, Procedures and Definitions, Edition 2"", published by the BRS. Specifically, the attributes adhere to the ALUM (Australian Land Use and Management) classification. Logical Consistency Not applicable Completeness Some areas of Australia are not yet complete.
