Vicmap Position - AGD66 and GDA94 Transformation Sample Point

The test data set can be used to test high accuracy coordinate transformation (for compiled GIS data) and coordinate conversion in and around Victoria in relation to the Geocentric Datum of Australia. The test data can be used to compare outputs from software that: · Claims to use the official Intergovernmental Committee on Survey and Mapping (ICSM) high accuracy combined 7 parameter/distortion model transformation process and incorporating or derived from file data contained in called National 66 (13.09.01).gsb (refer to (http://www.anzlic.org.au/icsm/gdatm/) which is provided in the National Transformation Version 2 (NTv2) grid file format.· Claims to perform conversions between coordinate types relating to the Australian Geodetic Datum and Geocentric Datum of Australia including:- Geographicals: Latitude and Longitude coordinates (ie AGD66 and GDA94),- Universal Transverse Mercator (UTM) grid coordinates (ie Australian Map Grid 1966 (AMG66) and Map Grid of Australia 1994 (MGA94)) and- Custom Lambert conformal conic projection coordinates relating to the Land Victoria Vicgrid66 and Vicgrid94 projection specifications as they apply to Victoria (refer to www.giconnections.vic.gov.au)

本测试数据集可用于测试针对已编译地理信息系统（Geographic Information System, GIS）数据的高精度坐标转换，以及澳大利亚地心基准面（Geocentric Datum of Australia, GDA）框架下维多利亚州及其周边区域的坐标转换工作。本数据集可用于对比符合以下两项要求的软件的输出结果：
· 声称采用官方测量与制图政府间委员会（Intergovernmental Committee on Survey and Mapping, ICSM）制定的高精度组合七参数/畸变模型转换流程，且整合或源自名为National 66 (13.09.01).gsb的文件数据，该数据以国家转换版本2（National Transformation Version 2, NTv2）格网文件格式存储，详细信息可参考http://www.anzlic.org.au/icsm/gdatm/；
· 声称可实现澳大利亚大地基准面（Australian Geodetic Datum, AGD）与GDA之间的各类坐标转换，具体涵盖：
- 地理坐标：纬度与经度坐标（即AGD66与GDA94基准下的坐标）；
- 通用横轴墨卡托（Universal Transverse Mercator, UTM）格网坐标：即1966年澳大利亚地图格网（Australian Map Grid 1966, AMG66）与1994年澳大利亚地图格网（Map Grid of Australia 1994, MGA94）；
- 适配维多利亚州的自定义兰伯特共形圆锥投影坐标：即符合维多利亚州土地局Vicgrid66与Vicgrid94投影规范的坐标，详细信息可参考www.giconnections.vic.gov.au
