Report on GPR and science investigations at Macquarie island and Casey station

Taken from the survey report:Documentation is provided for surveying tasks - by Tom Velthuis - at Macquarie Island and Casey, during the summer of 2000/1. The report is presented in five key sections:1. GPR related surveying in Thala Valley - Casey;2. Non GPR related surveying in Thala Valley;3. Surveys conducted outside of Thala Valley;4. Surveys at Macquarie Island; and5. Survey data to GIS.The first three sections relate to Casey; the fourth section to Macquarie Island; and the fifth section documents the transfer of data to GIS.For more details see the report available as part of the download.Taken from the readme file accompanying the data:The folder named, 'shape' contains projected (UTM) and unprojected shapefiles, based on WGS84, relating to surveys by Tom Velthuis at Macquarie Island and Casey during the summer 2000/2001 season. See report: Survey Report.doc.The folder named, 'excel_files' contains excel files by Tom Velthuis used for computing surveying work performed at Macquarie Island and Casey during the summer 2000/1. The 'Windmill Islands control' file is a file given to Tom by Tom Gordon.The folder labelled, 'tomv pics scanned' contains photographs (by Tom Velthuis) relating to surveying work conducted at Casey during the summer 2000/1. Most of the photos are in the report labelled, 'Survey Report.doc'.The folder labelled, 'TomVforGIS' contains files generated by Tom Velthuis, for the creation of shapefiles in ArcView.The files relate to Surveying work conducted at Macquarie Island and Casey during Summer 2000/1.macca_levels.xls has additional notes on the levelling of buildings at Macquarie Island.Also, map number 13248 in the SCAR Map Catalogue shows crosses on the buildings at Macquarie Island indicating the approximate location of levelling to the buildings. macca_levels.xls has the same content as the dbf file referred to on the map.See Related URL below for the SCAR Map Catalogue entry.

本数据集源自汤姆·韦尔特休斯（Tom Velthuis）于2000/2001年夏季在麦夸里岛（Macquarie Island）与凯西站（Casey）开展测量任务所配套的调查报告。该报告共分为五个核心章节：
1. 凯西站塔拉谷（Thala Valley）内与探地雷达（Ground Penetrating Radar, GPR）相关的测量工作；
2. 凯西站塔拉谷内与探地雷达无关的测量工作；
3. 塔拉谷以外区域开展的测量任务；
4. 麦夸里岛开展的测量工作；
5. 测量数据转至地理信息系统（Geographic Information System, GIS）流程。
其中前三个章节围绕凯西站展开，第四章聚焦麦夸里岛，第五章详细阐述了测量数据向GIS的迁移流程。如需获取更多细节，请下载附带的调查报告文件。

本数据集附带的自述文件说明如下：
名为`shape`的文件夹包含基于WGS84坐标系的投影（通用横轴墨卡托投影，Universal Transverse Mercator, UTM）与非投影格式的形状文件（shapefile），对应汤姆·韦尔特休斯于2000/2001年夏季在麦夸里岛和凯西站开展的测量工作相关内容，详见报告《Survey Report.doc》。
名为`excel_files`的文件夹包含汤姆·韦尔特休斯用于计算2000/2001年夏季麦夸里岛与凯西站测量作业数据的Excel文件，其中《Windmill Islands control》文件为汤姆·戈登（Tom Gordon）提供给汤姆·韦尔特休斯的文件。
名为`tomv pics scanned`的文件夹包含汤姆·韦尔特休斯拍摄的、与2000/2001年夏季凯西站测量工作相关的扫描照片，其中多数照片已收录于《Survey Report.doc》报告中。
名为`TomVforGIS`的文件夹包含汤姆·韦尔特休斯为在ArcView中生成形状文件所制作的相关文件，对应2000/2001年夏季麦夸里岛与凯西站的测量作业内容。
文件`macca_levels.xls`包含麦夸里岛建筑水准测量的补充说明。
此外，南极研究科学委员会（Scientific Committee on Antarctic Research, SCAR）地图目录中的编号13248号地图标注了麦夸里岛建筑上的十字标记，用于指示建筑水准测量的大致位置，`macca_levels.xls`文件与该地图中提及的dbf文件内容完全一致。如需查看该SCAR地图目录条目，请访问下方相关链接。
