NSW Office of Water - National Groundwater Information System 20141101v02

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied\n\n\n\nNote: This data has not been incorporated into the National Groundwater Information dataset as yet and is the latest extract provided by NSW Office of Water to the Bureau of Meteorology for incorporation in the National Groundwater Information System.\n\n\n\nThe NGIS geodatabase for was developed by lead water agencies from all States and Territories based on the NGIS data model, which was developed and maintained by the Bureau. Refer to the NGIS Data Dictionary and Schema Diagram (included) for further information on the NGIS data model.\n\n\n\nThe format for NGIS is an ESRI file geodatabase. ESRI ArcGIS Version 10 (or beyond) is needed to use NGIS.\n\n\n\nThe National Groundwater Information System (NGIS) is a geodatabase for storing nationally consistent groundwater data based on ESRI's ArcHydro for Groundwater data model. It focuses on bore and bore log (lithology, bore construction and hydrostratigraphy) data. It also includes georasters and geovolumes for selected areas.\n\nThe Bureau of Meteorology maintains the NGIS data model that standardises and spatially-enables groundwater data. The lead water agencies in each State/Territory (plus Water Corporation in Western Australia) export data from their corporate groundwater databases into State/Territory NGIS geodatabases. The Bureau of Meteorology maintains the NGIS data model and collates State/Territory geodatabases into the national geodatabase.\n\nThe data product extent is Geographic Australia (as defined by Acts Interpretation Act 1901). The product will be updated in December of each year following the receipt of updated State/Territory geodatabases at the end of September through the Water Regulations (Commonwealth legislation that requires agencies to deliver water data to the Bureau under the Water Act).\n\n\n\nThe NGIS contains the following datasets:\n\n\n\nBore - \tPoint feature class that represents the location of a bore and associated attributes. Multiple independently screened bore pipes are regarded as a separate bore features.\n\nBore log - Hydrostratigraphy log. Table with strata classified into hydrogeological units along a borehole\n\nLithology log\t- Table with driller's or geologist's description of rock or sediment types along a borehole\n\nConstruction log -\tTable with bore construction information along a borehole (e.g. casing and screen)\n\nBore line -\t3D line feature class that represents the hydrogeologic units along a borehole\n\nConstruction line\t- 3D line feature class that represents the construction information (e.g. casing and screen) along a borehole\n\nHydrogeologic unit -\tTable summarising hydrogeologic units and hydrogeologic complexes and their attributes. Includes both state/territory and National Aquifer Framework\n\n## **Purpose** \n\nThis version of NSW Office of Water NGIS extract has been used in the reprocessing of GW Economic Assets for Hunter and Glouster PAEs.\n\n## **Dataset History** \n\nThis update for NSW was compiled by NSW Office of Water and delivered to the Bureau to be ingested into the National Database.\n\n\n\nThe National Groundwater Information System is a spatial database that contains a range of groundwater information submitted by States and Territories. The system contains more than 800,000 bore locations with associated lithology logs, bore construction logs and hydrostratigraphy logs. 2D and 3D aquifer geometries are also available for some areas.\n\n\n\nHydrogeologic units within the system have been standardised for national consistency using the National Aquifer Framework.\n\n\n\nFor documentation on the data model, data dictionary and data product specification:\n\nhttp://www.bom.gov.au/water/groundwater/ngis/documentation.shtml\n\n## **Dataset Citation** \n\nNSW Office of Water (2014) NSW Office of Water - National Groundwater Information System 20141101v02.

## 摘要

本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交版本原样呈现。

注：该数据尚未纳入国家地下水信息数据集，此为新南威尔士州水务局（NSW Office of Water）向澳大利亚气象局（Bureau of Meteorology）提供的最新提取数据，用于纳入国家地下水信息系统（National Groundwater Information System, NGIS）。

国家地下水信息系统地理数据库由澳大利亚各州及领地的牵头水务机构基于NGIS数据模型开发，该数据模型由澳大利亚气象局开发并维护。如需了解NGIS数据模型的更多信息，请参阅附带的《NGIS数据字典与架构图》。

NGIS采用ESRI文件地理数据库（ESRI file geodatabase）格式，需使用ESRI ArcGIS 10及以上版本方可正常使用。

国家地下水信息系统（NGIS）是一套地理数据库，用于存储基于ESRI地下水ArcHydro数据模型构建的全国统一标准地下水数据。其核心聚焦于钻孔及钻孔测井（岩性、钻孔结构与水文地层学）数据，同时涵盖部分区域的地理栅格与地理体数据。

澳大利亚气象局负责维护NGIS数据模型，以实现地下水数据的标准化与空间化。各州/领地的牵头水务机构（含西澳大利亚州水务公司）将其企业地下水数据库中的数据导出至各州/领地的NGIS地理数据库中。澳大利亚气象局负责维护NGIS数据模型，并将各州/领地的地理数据库整合为全国性地理数据库。

本数据产品的覆盖范围为《1901年法案解释法》界定的澳大利亚全域。每年9月末收到各州/领地更新后的地理数据库后，本产品将于同年12月依据《水法》规定的联邦水务条例完成更新。

NGIS包含以下数据集：

- 钻孔：表示钻孔位置及相关属性的点要素类。多个独立过滤的钻孔管道将被视为独立的钻孔要素。
- 钻孔测井：水文地层学测井。沿钻孔孔段划分为水文地质单元的表格数据。
- 岩性测井：记录钻孔孔段岩石或沉积物类型的钻探人员或地质学家描述的表格数据。
- 结构测井：记录钻孔孔段钻孔结构信息（如套管与过滤段）的表格数据。
- 钻孔线：表示沿钻孔孔段水文地质单元的三维线要素类。
- 结构线：表示沿钻孔孔段结构信息（如套管与过滤段）的三维线要素类。
- 水文地质单元：汇总水文地质单元及水文地质综合体及其属性的表格数据，涵盖各州/领地数据与国家含水层框架（National Aquifer Framework）数据。

## 用途

本版新南威尔士州水务局NGIS提取数据已用于亨特与格洛斯特优先评估区（PAEs）地下水经济资产的再处理工作。

## 数据集历史

本次新南威尔士州更新数据由新南威尔士州水务局编制，并提交至澳大利亚气象局，以纳入国家数据库。

国家地下水信息系统是一款空间数据库，包含各州/领地提交的各类地下水信息。该系统收录了超过80万个钻孔位置及其相关的岩性测井、钻孔结构测井与水文地层学测井数据。部分区域还提供二维与三维含水层几何数据。

系统内的水文地质单元已通过国家含水层框架实现标准化，以确保全国数据的一致性。
