MBC Aquifer Hydrochemistry v01

## **Abstract** \n\nThis dataset was derived from provided by Geoscience Australia and the Queensland Department of Natural Resources and Mining. You can find a link to the source dataset in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.\n\n\n\nThis dataset contains a set of feature classes containing GIS point data and attributes derived from tabular GAB_hydrochem_QCedforCSGwaters11mapNO_CONFIDENTIAL.xlsx\n\n - GUID: (8e5cade2-c95a-45ec-9e6e-39b136d2b6d6). \n\nThe feature classes are split up according to each bore assigned aquifer extent using ArcGIS GIS processes to produce point, contour and raster data surfaces.\n\nPrior to being converted into GIS Feature Class, the source data had been through a quality assurance and validation process to ensure the reliability of chemistry sample values as well as to check the assigned aquifer formation for each bore.\n\n## **Purpose** \n\nThis dataset was created to display groundwater chemistry information spatially for each individual aquifer in the Surat Basin subregion. Information may be displayed as point data, or interpolated to display as contour and raster surfaces.\n\n## **Dataset History** \n\nThis dataset was created by converting tabular bore data to GIS feature class point data.\n\nThe conversion was done using ArcCatalog. \n\nFor each Aquifer in the source dataset - GUID: 8e5cade2-c95a-45ec-9e6e-39b136d2b6d6 (sheets were split up by aquifer formation name) a new point Feature Class was created.\n\nUsing ArcGIS GIS processesand tools, these point feature classes were derived: pH, Alkalinity and Total Dissolved Solids (TDS) for each aquifer extent.\n\nThese point feature classes were processed using ArcGIS tools to create pH, Alkalinity and TDS (Hydrochemistry) grids.\n\nContour feature class were derived from the grids.\n\nThe grids and contours were clipped to its own aquifer extent.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) MBC Aquifer Hydrochemistry v01.

**摘要**
本数据集源自澳大利亚地质调查局（Geoscience Australia）与昆士兰州自然资源与矿业部提供的原始数据。源数据集的链接可在本元数据声明的谱系字段（Lineage Field）中获取，本元数据声明的历史字段则说明了本数据集的衍生过程。

本数据集包含若干要素类，其数据源自表格文件`GAB_hydrochem_QCedforCSGwaters11mapNO_CONFIDENTIAL.xlsx`，包含地理信息系统（Geographic Information System，GIS）点数据及其属性信息，全局唯一标识符（Globally Unique Identifier，GUID）为：8e5cade2-c95a-45ec-9e6e-39b136d2b6d6。

本数据集通过ArcGIS地理信息系统工具，依据每个钻孔对应的含水层范围对要素类进行拆分，以生成点、等值线及栅格数据曲面。在转换为GIS要素类之前，源数据已完成质量保证与验证流程，以确保化学样品测试值的可靠性，并核查每个钻孔对应的含水层地层信息。

**数据集用途**
本数据集旨在对苏拉特盆地次区域内各含水层的地下水化学信息进行空间可视化展示。相关信息可通过点数据形式呈现，或通过插值生成等值线与栅格曲面进行展示。

**数据集历史**
本数据集通过将表格形式的钻孔数据转换为GIS要素类点数据而生成，该转换流程通过ArcCatalog完成。针对源数据集（全局唯一标识符：8e5cade2-c95a-45ec-9e6e-39b136d2b6d6）中的每个含水层（工作表按含水层地层名称拆分），均创建了一个新的点要素类。

借助ArcGIS地理信息系统工具与流程，针对每个含水层范围生成了以下点要素类：pH值、碱度与总溶解固体（TDS）。通过ArcGIS工具对上述点要素类进行处理，生成了pH值、碱度及总溶解固体（水化学）栅格。从上述栅格中提取生成等值线要素类，并将栅格与等值线裁剪至对应的含水层范围。
