Gippsland Basin potentiometric surfaces - Regional water table, Boisdale Aquifer and Latrobe Group Aquifer.

## **Abstract** \n\nThis dataset was derived by the Bioregional Assessment Programme from the Gippsland Basin Potentiometric Surfaces - Regional Watertable, Boisdale Aquifer and Latrobe Group Aquifer dataset (GUID: 94af5ab4-d83e-4440-972a-7e0578400095). You can find a link to the parent datasets 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 includes two sets of data:\n\n- Potentiometric surfaces converted to rasters\n\n- The rasters clipped to the Gippsland Bioregion boundary.\n\n\n\nAll units are in mAHD.\n\n## **Purpose** \n\nThe purpose of these diagrams are to give the reader an indicative view of the key potentiometric surfaces at the regional scale for the Bioregional Assessment for the years 1980 and 2012. The data originates from preliminary findings of the Conceptualisation and Calibration of the Gippsland Basin Groundwater Model Stage of the Victorian 1771 Water Science Studies.\n\n## **Dataset History** \n\nThe raster versions of the potentiometric surfaces were created using the 'Copy Raster' tool within ESRI ArcCatalogue 10.2. \n\nThese rasters were then clipped to the Gippsland Bioregional Boundary using the 'Extract by Mask (Spatial Analyst)' tool within ArcMap 10.2.\n\n\n\nBoisdale refers to the Boisdale aquifer.\n\nRegional refers to the water table across the bioregion.\n\nUpper Latrobe refers to the Latrobe Group aquifer.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2015) Gippsland Basin potentiometric surfaces - Regional water table, Boisdale Aquifer and Latrobe Group Aquifer..

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）从吉普斯兰盆地潜水面（Potentiometric surfaces）——区域地下水位（Regional watertable）、博伊斯代尔含水层（Boisdale Aquifer）和拉特罗布群含水层（Latrobe Group Aquifer）数据集（全局唯一标识符（Globally Unique Identifier，简称GUID）：94af5ab4-d83e-4440-972a-7e0578400095）衍生而来。您可在本元数据声明的谱系（Lineage）字段中找到原始数据集的链接。本元数据声明的历史（History）字段将详述本数据集的衍生流程。

本数据集包含两组数据：

- 转换为栅格数据（rasters）格式的潜水面数据

- 裁剪至吉普斯兰生物区域边界的栅格数据。

所有单位均采用mAHD。

## **用途**

本数据集旨在为读者提供1980年与2012年生物区域评估中区域尺度下的关键潜水面参考视图。该数据源自维多利亚州1771号水科学研究项目中吉普斯兰盆地地下水模型阶段的概念化与校准初步成果。

## **数据集历史**

潜水面的栅格版本通过ESRI ArcCatalogue 10.2中的「复制栅格（Copy Raster）」工具生成。

随后使用ArcMap 10.2中的「掩膜提取（Extract by Mask，空间分析工具）」工具，将上述栅格数据裁剪至吉普斯兰生物区域边界。

注：博伊斯代尔（Boisdale）指代博伊斯代尔含水层；“区域”（Regional）指代生物区域范围内的地下水位；“上拉特罗布”（Upper Latrobe）指代拉特罗布群含水层。
