Catchment Scale Land Use of Australia - Update March 2014

## This dataset has been superseded. An updated version of this dataset is available from the ABARES website. \r\n\r\nThis dataset is a national compilation of catchment scale land use data for Australia (CLUM), as at March 2014. It is a seamless raster dataset that combines land use data for all state and territory jurisdictions, compiled at a resolution of 50 metres by 50 metres. It has been compiled from vector land use datasets collected as part of state and territory mapping programs through the Australian Collaborative Land Use and Management Program (ACLUMP). Catchment scale land use data was produced by combining land tenure and other types of land use information, fine-scale satellite data and information collected in the field. The date of mapping (1997 to 2012) and scale of mapping (1:25 000 to 1:250 000) vary, reflecting the source data capture date and scale. This information is provided in a supporting polygon dataset. \r\n\r\nThe CLUM data shows a single dominant land use for a given area, based on the primary management objective of the land manager (as identified by state and territory agencies). Land use is classified according to the Australian Land Use and Management (ALUM) Classification version 7, a three-tiered hierarchical structure. There are five primary classes, identified in order of increasing levels of intervention or potential impact on the natural landscape. Water is included separately as a sixth primary class. Primary and secondary levels relate to the principal land use. Tertiary classes may include additional information on commodity groups, specific commodities, land management practices or vegetation information.

本数据集是截至2014年3月的澳大利亚流域尺度土地利用数据的全国性汇编（CLUM）。它是一个无缝栅格数据集，整合了澳大利亚所有州和领地辖区的土地利用数据，分辨率为50米×50米。该数据集基于各州和领地测绘项目中收集的矢量土地利用数据汇编而成，这些数据的收集是澳大利亚协作土地利用与管理项目（ACLUMP）的一部分。流域尺度土地利用数据通过整合土地权属、其他类型的土地利用信息、精细尺度卫星数据及实地采集信息生成。测绘日期（1997年至2012年）和测绘比例尺（1:25000至1:250000）存在差异，这反映了源数据的采集日期和比例尺。这些信息在配套的多边形数据集中提供。
