Victorian Land Use Information System 2014/2015

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 can be provided as a spatial dataset or in tabular format. 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. Land Cover 2014: Land cover classification accuracy statements for the entire state may not be representative of land cover classification accuracy levels in the north-west of the state due to a paucity of ground truth data in this area (particularly west of Swan Hill and north of Sea Lake). Users are advised to use this land cover information with discretion and contact the data custodians for further information if required. 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 2014/15 product, and ESRI symbology files for the data can be freely downloaded from the VLUIS project page on the Victorian Resources Online website:http://vro.agriculture.vic.gov.au/dpi/vro/vrosite.nsf/pages/vluisDOI 10.4226/92/58e72ebae5380

维多利亚州土地利用信息系统（Victorian Land Use Information System, VLUIS）数据集由经济发展、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式存在显著差异，旨在生成时序一致、格式规范的土地利用数据。该数据集覆盖维多利亚州全域，针对州内每一块地籍宗地（cadastral parcel）分别描述其土地保有权（Land tenure）、土地利用（Land use）与土地覆被（Land cover）情况：土地保有权与土地利用信息每两年更新一次，土地覆被信息则每年更新一次，时间跨度为2006年至2015年。数据可提供空间数据集或表格格式两种形式。

正确使用VLUIS数据，需明确其三大组成部分的差异。澳大利亚联邦2006年发布的《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的使用用途或物业类型；土地覆被指地球表层的物理地表，包括植被类型、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。当前其方法学仍在优化完善中，因此该数据集将持续迭代并推出后续版本。使用者需联系数据保管人以了解该数据集的技术细节与适配场景。

2014年土地覆被数据：由于该州西北部（尤其是天鹅山以西与西莱克以北区域）缺乏实地实测数据，全州范围的土地覆被分类精度声明可能无法代表该区域的实际分类精度。使用者需谨慎使用该土地覆被信息，如有需要可联系数据保管人获取更多详情。此外，土地覆被分类精度因类别而异，总体分类精度可能无法反映单个类别的精度水平。若使用者需要各类别的详细精度信息，请联系数据保管人。

本数据集并未替代LandUse100，该数据集在其生成时段（1996-2005年）内仍保持有效。
