Victorian Land Use Information System 2008/2009

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. To 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: Land 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. The Victorian Land Use Information System (VLUIS) is an ongoing project designed to maintain and manage the Victorian land use mapping dataset.The 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. Irrigation 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.Land 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.The dataset does not replace LandUse100 which is still valid for the time in which it was created (1996 - 2005).A metadata statement, for the VLUIS 2008/09 product, and ESRI symbology files for the data can be freely downloaded from the VLUIS project page:http://vro.depi.vic.gov.au/dpi/vro/vrosite.nsf/pages/vluisDOI: 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。其构建方法与传统土地利用信息编制方法存在显著差异，旨在生成长期稳定且一致的标准化数据。
该数据集覆盖维多利亚州全域土地，针对州内每宗地籍宗地（cadastral parcel），分别描述土地保有、土地利用与土地覆被三类信息：其中土地保有与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，更新时段涵盖2006年至2015年的各年份。数据以要素类（feature class）格式存储。
正确使用VLUIS数据前，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物业类型；土地覆被指地球物理表面，涵盖植被类型、土壤、裸露岩石与水体的各类组合，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推进的项目，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完善中，因此本数据集后续将进行迭代优化并发布新版本。建议使用者联系数据管护方，以获取该数据集的技术细节与适配自身使用需求的应用价值。灌溉活动信息将在可获取时纳入数据集。2006-2007年度无可用数据，2012-2013年度存在数据覆盖不全的情况，因此这两个年度的数据集均未包含灌溉活动信息。
土地覆被分类精度因类别而异，总体分类精度可能无法准确反映单个类别的分类精度。若使用者需要获取各类别的详细分类精度信息，请联系数据管护方。本数据集无法替代LandUse100，后者在其编制时段（1996-2005年）内仍保持有效性。
