Introduction to 3D Coordinate Transformation Service of NLSC e-GNSS Real-Time Kinematic System
摘要
內政部國土測繪中心e-GNSS即時動態定位系統（簡稱e-GNSS系統）採用VBSRTK定位技術，提供使用者即時且高精度之定位服務，測量成果為e-GNSS坐標系統，與法定坐標系統不同。為方便使用者可快速簡單地將測量成果轉換至法定與歷年e-GNSS坐標系統，e-GNSS系統提供三維坐標轉換服務，轉換後平面精度優於5公分，高程精度優於10公分，大部分測量工作均可直接應用轉換成果，節省測量工作成本與時間。

坐標轉換並列摘要
The e-GNSS real-time kinematic positioning system of the National Land Surveying and Mapping Center was based on VBS-RTK technique to provide high precision positioning services, it's coordinate system is different from legal coordinate systems, named e-GNSS coordinate system. The e-GNSS real-time kinematic positioning system has been able to provide 3D coordinate transformation service for users to transform surveying result from e-GNSS to legal coordinate systems. The transformed accuracy was better than 5cm for horizontal coordinates, and better than 10cm for ellipsoid and orthometric height individually. This majority of surveying assignments can enjoy the benefit and convenience of this service.
