The Tasmanian Land Use 2019 spatial data set is produced at catchment scale which is undertaken through the Australian Collaborative Land Use and Management Program (ACLUMP) using standards set out in the 'Guidelines for land use mapping in Australia: principals, procedures and definitions, 4th edition 2011' and 'Addendum to the Guidelines for land use mapping in Australia: principles, procedures and definition, 4th Edition'. Land use is classified by its prime use using a hierarchical structure, Australian Land Use and Management (ALUM) Classification version 8, allowing land uses to be attributed as broad classes to individual commodities where possible. This produces nationally consistent land use mapping to inform, support and enable innovation and action in response to economic, social and environmental challenges. Land use information shows how we use the landscape, whether that is for food production, forestry, nature conservation, water storage or urban development. The data set has been derived through spatial analysis of ancillary data sets, interpretation from imagery (Google Earth, State Orthophoto and Landsat composite) and expert knowledge and data from stakeholders. A modelling process used to partially create Tasmanian Land Use 2015 was updated and used to partially create the 2019 data set allowing a repeatable process for future iterations of land use mapping. The land use mapping coverage is available for mixed dates at a scale that varies according to the intensity of land use activities and landscape context. This iteration of land use mapping has been predominately updated in areas of nature conservation, managed resource protection, perennial horticulture, irrigation, intensive animal production and plantation forests. Land use mapping is completed to the ALUM secondary and tertiary level with commodity information where available. The Australian Land Use and Management (ALUM) Classification has a three-tiered hierarchical structure. Primary, secondary and tertiary classes are broadly structured by the potential degree of modification and the impact on a putative "natural state" (essentially, a native land cover). Primary and secondary classes relate to land use 'the main use of the land', defined by the management objectives of the land manager. Tertiary classes can include commodity groups, specific commodities, land management practices or vegetation information. Tertiary-level data are particularly valuable in many natural resource planning and management applications but are often expensive to collect. The ALUM Classification includes six primary classes. The five primary classes of land use are distinguished in order of increasing levels of intervention or potential impact on the natural landscape. Water is also included as a sixth primary class The primary classes of land use in the ALUM Classification are: 1. Conservation and natural environments - land used primarily for conservation purposes, based on maintaining the essentially natural ecosystems present 2. Production from relatively natural environments - land used mainly for primary production with limited change to the native vegetation 3. Production from dryland agriculture and plantations - land used mainly for primary production based on dryland farming systems 4. Production from irrigated agriculture and plantations - land used mostly for primary production based on irrigated farming 5. Intensive uses - land subject to extensive modification, generally in association with closer residential settlement, commercial or industrial uses 6. Water - water features (water is regarded as an essential aspect of the classification, even though it is primarily a land cover type, not a land use).

Position Accuracy: 25m Varies according to imagery and data age and source. Attribute Accuracy: The data set contains fields and attributes from ALUMC v8 as outlined in the data specifications of 'Guidelines for land use mapping in Australia: principles, procedures and definitions, 4th edition 2011' and ÃÃÃâÃÃÃÿÃÃÃÿAddendum to the Guidelines for land use mapping in Australia: principles, procedures and definition, 4th EditionÃÃÃâÃÃÃÿÃÃÃÿ as required by Australian Collaborative Land Use and Management Program (ACLUMP). Logical Consistency: All polygon data is topologically correct. Completeness: The data set covers the whole state including Flinders and King Islands, all records have the required attributes Additional: http://www.agriculture.gov.au/abares/aclump/land-use/land-use-mapping https://dpipwe.tas.gov.au/agriculture/land-management-and-soils/land-use-information
