Survey report March 2002 Voyage 8 Australian Antarctic Division Authors - John VanderNiet / Nick Bowden / Office of the Surveyor General, Tasmania

Field Program as Planned- Survey for coordination of the survey control network on ITRF 2000.- Checking the accuracy of the recently completed Macquarie Island topographic map.- Correction of a known map contour anomaly on Wireless Hill.- Mapping of new structures in the ANARE station area.- Maintenance of existing survey control marks- Tide gauge levelling - assistance to Bob Twilley of Geosciences Australia.- Sea level calibration of the tide gauge situated adjacent to the ANARE station.Field Program as ImplementedAll field survey was carried out using Lieca 530 dual frequency GPS; in the static mode for control and post processed kinematic for mapping.Wednesday 13th March- Inspection of tide gauge site and AUS91, AUS92, AUS228 and AAE BM1.- Ground survey in area of survey anomaly and other discrete features on Wireless Hill.- Survey for coordination of NMX/1 on ITRF 2000.Thursday 14th March to Sunday 17th March- Inspection/maintenance of existing survey control marks NMAX/1, NMX/1, AUS190, AUS191,AUS227, ST937, NMX/6, NMX/7.- Survey for coordination of NMX/7, NMX/6, AUS188 (mark damaged), AUS191 and ST937 for coordination of the Macquarie Island on ITRF2000.- Placement and survey of SPM10581 at Green Gorge hut.- Survey on the southern half of Macquarie Island for map checking purposes. Survey of a representative sample of tracks, lakes, ridges and natural surface for heights and HWM.Monday 18th March- Mapping of new structures in the ANARE station area.- Survey on the isthmus area adjacent to the ANARE station, mapping the HWM and coastal vegetation edge, and a further number of discrete features.- Assistance to Bob Twilley of Geosciences Australia in first order levelling of the tide gauge / ARGN GPS station (MAC1 / AUS211) connection.Sea level calibration of the tide gauge situated adjacent to the ANARE station was not achieved due to time limitations and rough sea conditions during the potentially available time for this activity.The survey report is available for downloading - see the Related URLs below.The Australian Antarctic Data Centre has included in its GIS database three polygons from the survey data relating to section 4 of the report. The polygons represent three buildings at Macquarie Island Station: the Stores Annex erected in January 2001, the Vehicle Shed and the Boat Shed. The Stores Annex was damaged by a storm in 2003 and was removed during the 2003-04 summer. The Vehicle Shed and the Boat Shed are included in the Macquarie Island station buildings GIS data available for downloading from a Related URL below. These two polygons have Dataset_ID = 125.Further information contained in "Survey report: 'Macquarie Island, OSG Survey Campaign, Voyage 8 Round Trip March 2002'."

规划内野外作业
- 针对ITRF 2000框架下测量控制网的坐标联测工作
- 对新近完成的麦夸里岛（Macquarie Island）地形图开展精度核验
- 修正无线山（Wireless Hill）处已发现的地形图等高线异常问题
- 绘制ANARE站区新增地物的地形图
- 开展现有测量控制点的维护工作
- 潮位水准测量——协助澳大利亚地球科学局（Geosciences Australia）的鲍勃·特威利（Bob Twilley）开展相关工作
- 对ANARE站附近的潮位计实施海平面校准作业

实际执行的野外作业
所有野外测量均采用徕卡（Lieca）530双频全球定位系统（GPS）接收机完成：控制测量采用静态模式，地形图测绘采用后处理动态定位模式。

3月13日 星期三
- 巡检潮位计站点及AUS91、AUS92、AUS228与AAE BM1控制点
- 对无线山存在测量异常的区域及其他离散地物开展地面测量
- 针对ITRF 2000框架下NMX/1控制点的坐标联测工作

3月14日 星期四 至 3月17日 星期日
- 对现有测量控制点NMAX/1、NMX/1、AUS190、AUS191、AUS227、ST937、NMX/6及NMX/7进行巡检与维护
- 针对ITRF 2000框架下麦夸里岛坐标联测需求，开展NMX/7、NMX/6、受损的AUS188控制点、AUS191及ST937的坐标联测工作
- 在绿谷小屋（Green Gorge hut）处布设SPM10581控制点并开展测量
- 为完成地形图核验，对麦夸里岛南部区域开展测量：选取典型路段、湖泊、山脊与自然地表样本，测量其高程及高潮位线（HWM）

3月18日 星期一
- 绘制ANARE站区新增地物的地形图
- 对ANARE站附近的地峡区域开展测量，绘制高潮位线与海岸植被边界，并对更多离散地物进行测绘
- 协助澳大利亚地球科学局的鲍勃·特威利开展潮位计/ARGN GPS站（MAC1 / AUS211）的一等水准联测工作

由于本次作业可利用时段内时间有限且海况恶劣，未能完成ANARE站附近潮位计的海平面校准作业。

澳大利亚南极数据中心（Australian Antarctic Data Centre）已将本报告第4章节相关的测量数据中的3个多边形要素纳入其地理信息系统（GIS）数据库。该3个多边形分别对应麦夸里岛站的3座建筑：2001年1月搭建的物资附属仓库、车辆棚及船艇棚。物资附属仓库于2003年遭风暴损毁，并在2003-2004年夏季被拆除。车辆棚与船艇棚已纳入麦夸里岛站建筑GIS数据集，可通过下文相关链接下载获取，这两个多边形要素的数据集编号（Dataset_ID）为125。
