Victorian Land Use Information System 2010/2011

The Victorian Land Use Information System (VLUIS) dataset has been created by the Spatial Information Sciences Group of the Agriculture Research Division in the Department of Economic Development, Jobs, Transport, and Resources. The method used to create VLUIS is significantly different to traditional methods used to create land use information and has been designed to create regular and consistent data over time. It covers the entire landmass of Victoria and separately describes the land tenure, land use and land cover for each cadastral parcel across the state, biennially for land tenure and use and annually for land cover; for each year from 2006 to 2015. The data is in the form of a feature class. \n\nTo use the VLUIS data correctly it is important to understand the difference between the three components of VLUIS. The Guidelines for land use mapping in Australia: principles, procedures and definitions, Edition 3 published in 2006 by the Commonwealth of Australia, defines them as follows: \nLand tenure is the ownership and leasehold interests in land (VLUIS only reports ownership). Land use means the purpose to which the land cover is committed or the property type. Land cover refers to the physical surface of the earth, including various combinations of vegetation types, soils, exposed rocks and water bodies as well as anthropogenic elements, such as agriculture and built environments. \nThe Victorian Land Use Information System (VLUIS) is an ongoing project designed to maintain and manage the Victorian land use mapping dataset.\n\nThe methodology is still being refined and as such the dataset is subject to improvements and the release of later versions. It is important you speak to the custodian to be advised of the technical details of the dataset and its utility for your desired use. \n\nLand cover classification accuracy varies between classes and the overall classification accuracy may be misleading in terms of the accuracy of an individual class. Users are asked to contact the data custodians for detailed class accuracy information if required for their purposes.\n\nIrrigation activity is included when available. The data was not available in 2006-07 and there was incomplete coverage in 2012-13 and therefore the irrigation activity was not included in either of those datasets.\n\nThe dataset does not replace LandUse100 which is still valid for the time in which it was created (1996 - 2005).\n\nA metadata statement, for the VLUIS 2010/11 product, and ESRI symbology files for the data can be freely downloaded from the VLUIS project page:\nhttp://vro.depi.vic.gov.au/dpi/vro/vrosite.nsf/pages/vluis\n\n\nDOI: http://dx.doi.org/10.5061/dryad.n08t0

维多利亚州土地利用信息系统（Victorian Land Use Information System, 简称VLUIS）数据集由维多利亚州经济发展、就业、交通与资源部农业研究分部空间信息科学小组编制。该数据集的构建方法与传统土地利用信息编制方法存在显著差异，旨在生成时序上规则且一致的土地数据。其覆盖维多利亚州全域，针对州内每宗地籍宗地分别描述土地保有权、土地利用与土地覆被情况：其中土地保有权和土地利用数据每两年更新一次，土地覆被数据每年更新一次，时间跨度为2006年至2015年。数据集以要素类（feature class）形式存储。

若要正确使用VLUIS数据，需明晰其三大组成部分的差异。2006年澳大利亚联邦发布的《澳大利亚土地利用制图指南：原则、流程与定义（第3版）》对三者的定义如下：土地保有权指土地的所有权与租赁权益（VLUIS仅记录所有权信息）；土地利用指土地覆被所服务的用途或宗地的产业类型；土地覆被指地球的物理表面，包括各类植被组合、土壤、裸露岩石与水体，以及农业、建成环境等人为要素。

维多利亚州土地利用信息系统是一项持续性项目，旨在维护与管理维多利亚州土地利用制图数据集。目前其方法学仍在优化迭代中，因此本数据集将持续改进并推出后续版本。建议用户联系数据保管人，以了解该数据集的技术细节与适配自身应用场景的实用性。

土地覆被分类的精度因类别而异，总体分类精度可能无法准确反映单个类别的实际精度。若用户需要特定类别的详细精度信息，请联系数据保管人获取。

灌溉活动数据在可获取时会纳入数据集。2006-2007年度无可用数据，2012-2013年度存在覆盖不全的情况，因此这两个年度的数据集均未包含灌溉活动相关数据。

本数据集并非LandUse100的替代产品，后者在其编制的时间范围（1996年至2005年）内仍具备有效性。
