Probable Vegetation Groundwater Dependent Ecosystems - Namoi

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, Southern Tablelands, 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

本项目旨在创建一套数据集，用于识别新南威尔士州（New South Wales, NSW）内有可能属于地下水依赖生态系统（Groundwater Dependent Ecosystem, GDE）的植被群落。概率分类分为高、中、低以及非GDE四类。该数据集需满足水分配计划与水资源计划的法定要求，可作为基础数据图层，辅助开展研究项目、州级重大开发申请评估、许可申请及合规审查等工作。

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-吉德尔（Border Rivers-Gwydir）、中部台地（Central Tablelands）、中西部（Central West）、霍克斯伯里-尼皮恩（Hawkesbury-Nepean）、亨特-中部河流（Hunter-Central Rivers）、拉克兰（Lachlan）、下默里-达令（Lower Murray Darling）、默里-姆伦比奇（Murray-Murrumbidgee）、纳莫伊（Namoi）、北部河流（Northern Rivers）、南部河流（Southern Rivers）、南部台地（Southern Tablelands）、悉尼都会区（Sydney Metro）以及西部片区（远西部及默里-达令流域管理局（Murray-Darling Basin Authority, MDBA）管辖区域）。

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。针对特定场地开展审查的新南威尔士州规划与环境部水利相关作业（如钻井许可申请）可能需要后续验证以确认结果。
