Potentiometric Surface Cadna-Owie Hooray grid v02

## **Abstract** \n\nThis dataset was derived by the Bioregional Assessment Programme. The source dataset is 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 dataset show the potentiometric surface for the Cadna-Owie/Hooray aquifer of the Great Artesian Basin as continuous raster. The raster dataset is derived using contour input data sourced from: Great Artesian Basin - Cadna-owie Hooray Potentiometric Surface, GUID: a72d30b3-29de-46a6-a467-990396860bd4\n\n## **Purpose** \n\nThis dataset provides a continuous potentiometric surface for the Cadna-Owie/Hooray aquifer to enhance the visualisation of groundwater pressure data within the aquifer\n\n## **Dataset History** \n\nThis dataset was created by interpolating input contour line features from the dataset: Potentiometric surface for the Cadna-owie-Hooray and equivalents Aquifer, GUID: bbf78bf8-9ef6-42c1-861d-b2f57afd9805, into a gridded surface using the Topo To Raster tool (Spatial Analayst) in ArcGIS.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) Potentiometric Surface Cadna-Owie Hooray grid v02.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）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，而本衍生数据集的制作流程则详见元数据声明的“历史（History）”字段。

本数据集以连续栅格形式呈现大自流盆地（Great Artesian Basin）Cadna-Owie/Hooray含水层的测压水头面。该栅格数据集由源自以下数据集的等值线输入数据生成：大自流盆地——Cadna-owie Hooray测压水头面，全局唯一标识符（GUID）：a72d30b3-29de-46a6-a467-990396860bd4。

**目的**
本数据集为Cadna-Owie/Hooray含水层提供连续的测压水头面，以优化该含水层内地下水压力数据的可视化效果。

**数据集历史**
本数据集通过对源数据集《Cadna-owie-Hooray及等效含水层测压水头面》（全局唯一标识符（GUID）：bbf78bf8-9ef6-42c1-861d-b2f57afd9805）中的等值线要素进行插值处理，并使用ArcGIS中空间分析（Spatial Analyst）工具集的地形转栅格（Topo To Raster）工具生成网格化曲面而创建。
