Galilee Drawdown Rasters

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets.\n\nThe source datasets are identified in the Lineage field in this metadata statement.\n\nThe processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\n\n\nThis dataset contains rasters of the 5th, 50th and 95th percentile of drawdown in the model layers as well as grids of the probability of exceeding 0.2, 2 and 5 m drawdown as estimated with the GAL AEM model. The original rasters have been modified slightly so as to produce maps. These maps are an essential part of the visualisation of groundwater model results in Peeters et al. 2017). The process involved in creating these is described in the history.\n\n\n\nPeeters L, Ransley T, Turnadge C, Kellett J, Harris-Pascal C, Kilgour P and Evans T (2016) Groundwater numerical modelling for the Galilee subregion.

The Clematis rasters were clipped using Clematis_warang_top_extent and the BCB rasters were clipped using Bandanna_top_extent.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) Galilee Drawdown Rasters.

## **摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多源数据集衍生而来。
源数据集的相关信息已在本元数据声明的溯源（Lineage）字段中列明。
本衍生数据集的生成流程已在本元数据声明的历史（History）字段中予以说明。

本数据集包含模型层中水位降深的5%、50%、95%分位数栅格，以及基于GAL航空电磁（GAL AEM）模型估算得到的、水位降深超过0.2m、2m、5m的概率栅格。原始栅格已经过小幅修改以生成可视化地图，此类地图是Peeters等人2017年研究中地下水模型结果可视化的核心组成部分。此类地图的制作流程已在历史字段中详述。

Peeters L、Ransley T、Turnadge C、Kellett J、Harris-Pascal C、Kilgour P及Evans T（2016）：《加拉西（Galilee）子区域地下水数值模拟》，源自艾尔湖盆地生物区域评估的加拉西子区域成果2.6.2，澳大利亚环境部、澳大利亚气象局（Bureau of Meteorology）、联邦科学与工业研究组织（CSIRO）及澳大利亚地质科学局（Geoscience Australia）。

## **数据集历史**
本加拉西水位降深栅格基于GAL_分位数插值_v2（GAL_quantile_interpolation_v2，标识符：c7c4f7d0-ed25-475b-abcc-de7a1cbca3c3），依托ArcGIS平台制作，用于生成可视化地图。
该栅格的制作流程为：先将原始ASCII栅格转换为TIFF格式，再将TIFF栅格裁剪至适配范围。
Clematis与BCB两类栅格均通过GAL_模型含水层范围（GAL_Model_Aquifer_Extents，标识符：5afbf7f1-1ee0-444b-9f77-dbad8d8de95b）的配套数据集完成裁剪：其中Clematis栅格使用Clematis_warang_top_extent范围裁剪，BCB栅格则使用Bandanna_top_extent范围裁剪。
