GLO Stratford Open Cut Pits v01

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. The parent datasets are identified in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.\n\n\n\nThe dataset is a shapefile representing the approximate extents of the open cut pits (both existing and proposed) for the Stratford coal mine in the Gloucester sub-region. These were digitised from map images taken from Stratford Extension Project Environmental Impact Statement Appendix A - Groundwater Assessment. Figure A-2, pp A-76. \n\n\n\nhttp://www.stratfordcoal.com.au/documents/environment/eis/Appendix%20A%20-%20Groundwater%20Assessment.pdf\n\n## **Dataset History** \n\nA map image from the report listed below was scanned. These were georectified to MGA 56 geotiffs using recognised features of known locations in the various map images as control points (e.g. road junctions, corners of administrative boundaries etc). \n\n\n\nSelected features representing the open cut pits (both existing and proposed) shown on the map were manually digitised off the computer screen using a georectified map as a backdrop. Features were saved as ESRI shapefiles in the MGA z56 projection.\n\n\n\n\n\nStratford Mine:\n\n\n\nStratford Extension Project Environmental Impact Statement Appendix A - Groundwater Assessment.

## 摘要

本数据集由生物区域评估计划（Bioregional Assessment Programme）衍生编制，其原始数据源自多组数据集。本数据集的父级数据源信息详见本元数据声明中的谱系字段（Lineage Field），而历史字段（History Field）则详细记载了本数据集的具体构建流程。

本数据集为形状文件（shapefile），用于展示澳大利亚格洛斯特次区域（Gloucester sub-region）内斯特拉特福德煤矿（Stratford coal mine）现有及规划露天采坑的近似范围。该范围源自《斯特拉特福德扩建项目环境影响评价附录A：地下水评估（Stratford Extension Project Environmental Impact Statement Appendix A - Groundwater Assessment）》中图A-2（第A-76页）的地图图像，经数字化处理后得到。

## 数据集历史

首先对下述报告中的地图图像进行扫描，随后以各类地图图像中已知位置的标志性地物（如道路交叉口、行政边界拐点等）作为控制点，将扫描图像校正为MGA 56坐标系的GeoTIFF格式文件。

以校正后的地图为底图，在计算机屏幕上手动数字化提取地图中代表现有及规划露天采坑的目标要素，并将提取的要素以ESRI形状文件格式保存，投影坐标系采用MGA z56。
