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。
The e-GNSS real-time kinematic positioning system of the National Land Surveying andMapping Center was based on VBS-RTK technique to provide high precision positioning services, it’scoordinate system is different from legal coordinate systems, named e-GNSS coordinate system. Thee-GNSS real-time kinematic positioning system has been able to provide 3D coordinate transformationservice for users to transform surveying result from e-GNSS to legal coordinate systems. Thetransformed accuracy was better than 5 cm for horizontal coordinates, and better than 10 cm forellipsoid and orthometric height individually. This majority of surveying assignments can enjoy thebenefit and convenience of this service. |
