Victorian Land Use Information System 2016

The Victorian Land Use Information System (VLUIS) 2016 dataset has been created by the Spatial Sciences Group of the Agriculture Victoria Research Division in the Department of Economic Development, Jobs, Transport, and Resources. It covers the entire landmass of Victoria and separately describes the land tenure, land use and land cover across the state at the cadastral parcel level.The methodology for creating the VLUIS is described in Morse-McNabb et al. (2015) with the following notable changes:1. Land use data provided by the Office of the Valuer-General of Victoria for the 2014 year has been used as a base input. Readily available sources of land use information from government and industry have been used to provide updates to the land tenure and land use components of the 2016 dataset. This update process has not been exhaustive and will continue as new data sources become available. Parcels that have been updated and the source of their updates have been recorded in the attribute table of the dataset. The land cover mapping method remains unchanged to previous versions of the VLUIS.2. Land parcels within urban areas, mapped in previous versions, have been masked out vastly reducing the size of the 2016 dataset.The data is in the form of an ESRI 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 form of an interest in land. Some forms of tenure (such as pastoral leases or nature conservation reserves) relate directly to land use and land management practice. Land use means the purpose to which the land cover is committed. Some land uses, such as agriculture, have a characteristic land cover pattern. These usually appear in land cover classifications. Other land uses, such as nature conservation, are not readily discriminated by a characteristic land cover pattern. For example, where the land cover is woodland, land use may be timber production or nature conservation. 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. Land cover classes can usually be discriminated by characteristic patterns using remote sensing.A metadata statement, for the VLUIS 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 10.4226/92/590abbe6ea3f1

维多利亚州土地利用信息系统（Victorian Land Use Information System, VLUIS）2016数据集由维多利亚州经济发展、就业、交通和资源部下属农业维多利亚研究部门的空间科学小组构建。该数据集覆盖维多利亚州全境，并在地籍地块层面分别描述了全州的土地权属、土地利用及土地覆盖情况。

VLUIS的构建方法详见Morse-McNabb等人（2015）的研究，其中包含以下显著变更：
1. 采用维多利亚州总评估师办公室提供的2014年度土地利用数据作为基础输入；利用政府及行业现有可用的土地利用信息源，对2016年数据集的土地权属及土地利用部分进行更新。本次更新尚未穷尽所有可能，后续将随新数据源的出现持续推进。已更新的地块及其更新来源已记录在数据集的属性表中。VLUIS的土地覆盖制图方法与之前版本保持一致。
2. 此前版本中绘制的城市区域内地块已被掩膜处理，大幅缩减了2016年数据集的规模。

该数据采用ESRI要素类格式。若需正确使用VLUIS数据，理解其三大核心组件的差异至关重要。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》（第三版）对上述概念定义如下：
- 土地权属（land tenure）：指土地权益的形式。部分权属形式（如牧场租赁或自然保护区）与土地利用及土地管理实践直接相关。
- 土地利用（land use）：指土地覆盖所服务的用途。部分土地利用类型（如农业）具有特征性的土地覆盖模式，通常会出现在土地覆盖分类中；其他类型（如自然保护）则无法通过特征性土地覆盖模式轻易区分。例如，当地面覆盖为林地时，土地利用可能是木材生产或自然保护。
- 土地覆盖（land cover）：指地球的物理表面，包括植被类型、土壤、裸露岩石、水体等的各种组合，以及农业、建成环境等人造元素。土地覆盖类别通常可通过遥感技术依据特征模式加以区分。
