Namoi bore analysis rasters - updated

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis resource contains raster datasets created using ArcGIS to analyse groundwater levels in the Namoi subregion.\n\n\n\nThis is an update to some of the data that is registered here: http://data.bioregionalassessments.gov.au/dataset/7604087e-859c-4a92-8548-0aa274e8a226\n\n## **Purpose** \n\nThese data layers were created in ArcGIS as part of the analysis to investigate surface water - groundwater connectivity in the Namoi subregion. The data layers provide several of the figures presented in the Namoi 2.1.5\tSurface water - groundwater interactions report.\n\n## **Dataset History** \n\nExtracted points inside Namoi subregion boundary. Converted bore and pipe values to Hydrocode format, changed heading of 'Value' column to 'Waterlevel' and removed unnecessary columns then joined to Updated_NSW_GroundWaterLevel_data_analysis_v01\\NGIS_NSW_Bore_Join_Hydmeas_unique_bores.shp clipped to only include those bores within the Namoi subregion.\n\nSelected only those bores with sample dates between >=26/4/2012 and =1/5/2006 and

## **摘要**

本数据集由生物区域评估计划从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谱系（Lineage）字段中注明，而该衍生数据集的生成流程则在元数据声明的历史（History）字段中予以说明。

本资源包含使用ArcGIS创建的栅格数据集，用于分析纳莫伊次区域（Namoi subregion）的地下水位情况。

本数据集是对以下注册数据的更新：http://data.bioregionalassessments.gov.au/dataset/7604087e-859c-4a92-8548-0aa274e8a226

## **用途**

这些数据图层是在ArcGIS中创建的，作为纳莫伊次区域地表水-地下水连通性调查分析的一部分。这些数据图层对应《纳莫伊2.1.5 地表水-地下水交互作用报告》中呈现的多幅图表。

## **数据集历史**

提取纳莫伊次区域（Namoi subregion）边界内的点位。将钻孔与管道监测值转换为Hydrocode格式，将"Value"列的列名更改为"Waterlevel"，删除不必要的列，随后与裁剪至仅包含纳莫伊次区域内钻孔的Updated_NSW_GroundWaterLevel_data_analysis_v01NGIS_NSW_Bore_Join_Hydmeas_unique_bores.shp进行关联。

仅选取采样日期介于2012年4月26日至2006年5月1日之间的钻孔，并
