National Groundwater Information System (NGIS) v1.1

## **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\nThe National Groundwater Information System (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 (NAF) terminology.\n\n## **Dataset History** \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\nBureau of Meteorology (2013) National Groundwater Information System (NGIS) v1.1.

**摘要**

本数据集及其元数据声明由第三方提交至生物区域评估计划（Bioregional Assessment Programme），本文档按原始提交内容原样呈现。

国家地下水信息系统（National Groundwater Information System, NGIS）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，该数据模型由澳气象局（Bureau of Meteorology）开发并维护。如需了解NGIS数据模型的更多信息，请参阅随附的NGIS数据字典与架构图。

NGIS采用ESRI文件地理数据库格式，需使用ESRI ArcGIS 10及以上版本方可访问该数据集。

国家地下水信息系统（NGIS）是基于ESRI地下水ArcHydro数据模型构建的地理数据库，用于存储全国统一标准的地下水数据。其核心涵盖钻孔及钻孔日志（岩性、钻孔结构与水文地层学）数据，同时包含部分选定区域的地理栅格与地理体数据。

澳气象局（Bureau of Meteorology）负责维护用于标准化并实现地下水数据空间化的NGIS数据模型。各州及领地的牵头水务机构（西澳大利亚州另含水务公司）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，随后由澳气象局将各州/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》所定义的澳大利亚全境。每年9月末各州/领地提交更新后的地理数据库后，本产品将于同年12月完成更新，更新流程依据《水条例》（联邦立法，要求各机构根据《水法》向澳气象局提交水务数据）执行。

NGIS包含以下数据集：

钻孔（Bore）：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将被视为独立的钻孔要素。

钻孔日志（Bore log）：水文地层日志，为沿钻孔将地层划分为水文地质单元的数据表。

岩性日志（Lithology log）：记录钻井人员或地质学家对钻孔沿线岩石或沉积物类型描述的数据表。

结构日志（Construction log）：记录钻孔沿线结构信息（如套管与过滤器）的数据表。

钻孔线（Bore line）：表示钻孔沿线水文地质单元的三维线要素类。

结构线（Construction line）：表示钻孔沿线结构信息（如套管与过滤器）的三维线要素类。

水文地质单元（Hydrogeologic unit）：汇总水文地质单元及水文地质综合体及其属性的数据表，同时涵盖各州/领地术语与全国含水层框架（National Aquifer Framework, NAF）术语。

**数据集历史**

国家地下水信息系统是一款空间数据库，收纳各州及领地提交的各类地下水数据。本系统包含超过80万个钻孔点位及其关联的岩性日志、钻孔结构日志与水文地层日志，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依据全国含水层框架实现标准化，以保障全国数据的一致性。
