地圖編製時,所引用之華準控制點,其精密度愈高,則成圖之精度必然愈高。本文旨在應用整合大地測量之理論,將所有可使用之大地測量資料整合,利用是嚴密的數學模式以計算出高精度控制點之三度空間座標,作爲各種地圖製作時引用之參考依據。同時亦可計算出重力持有擾動位之函數量(如大地起伏、垂線偏差、重力異常等),以供重力場研究及重力場圍製作之用。
When compiling a map, we know that the more precise the control points are, the more precise the map will be. This paper applies Integrated Geodesy approach, which integrates all available geodetic observations in a rigorous collocation model, to calculate the three dimensional coordinates of control points as the reference of the map compilation. At the same time, we can also get the functions of the disturbing potential-such as the geoidal undulation, the deflection of the vertical, and the gravity anomaly-to make a research in the gravity field and to compile the gravity field map.
