Spatial Layer of Probable Vegetation Groundwater Dependent Ecosystems in NSW

The purpose of this project is to create a data set that identifies vegetation communities that have a probability of being a groundwater dependent ecosystem within NSW. Probability categories are high, medium, low and non GDE. The data is required to meet legislative requirements for water sharing plans and water resource plans. This is a base data layer that can be used to aid research projects, assessment of state significant development applications, licence applications and compliance issues. For ease of data modelling and management, the dataset was divided into the following catchment management areas; Border Rivers-Gwydir, Central Tablelands, Central West, Hawkesbury-Nepean, Hunter-Central Rivers, Lachlan, Lower Murray Darling, Murray-Murrumbidgee, Namoi, Northern Rivers, Southern Rivers, Sydney Metro and Western Division (Far West and Western MDBA). \r\n\r\nPlease note: Groundwater Dependent Ecosystem mapping used the NSW DPE Environment and Heritage vegetation mapping product as the underlying data source. NSW DPE Water activities such as bore applications that are examined at a site specific scale may need subsequent verification to confirm.\r\n\r\nMethod report is available via the DoI Water website - https://water.dpie.nsw.gov.au/__data/assets/pdf_file/0010/151894/High-Probability-GDE-method-report.pdf

本项目旨在构建一套数据集，用于识别新南威尔士州（New South Wales，NSW）内具备地下水依赖生态系统（Groundwater Dependent Ecosystem，GDE）潜在概率的植物群落。其概率等级划分为高、中、低及非地下水依赖生态系统四类。该数据集需满足水分配计划与水资源规划的法定要求，可作为基础数据图层，为相关研究项目、州级重大开发申请许可、牌照申请及合规审查工作提供支撑。为便于数据建模与管理，本数据集按以下流域管理区域进行划分：边境河流-吉迪尔（Border Rivers-Gwydir）、中部台地（Central Tablelands）、中西部（Central West）、霍克斯伯里-内皮尔（Hawkesbury-Nepean）、亨特-中央河流（Hunter-Central Rivers）、拉克兰（Lachlan）、下墨累-达令（Lower Murray Darling）、墨累-默伦比奇（Murray-Murrumbidgee）、纳莫伊（Namoi）、北部河流（Northern Rivers）、南部河流（Southern Rivers）、悉尼都会区（Sydney Metro）及西部区域（远西部与墨累-达令流域管理局西部分区，Western Division (Far West and Western MDBA)）。

请注意：本次地下水依赖生态系统制图以新南威尔士州规划与环境部（NSW DPE）的环境与遗产植被制图产品作为基础数据源。新南威尔士州规划与环境部的水资源相关作业（如经场地特定尺度审查的钻井申请）可能需要后续验证以确认最终结果。
