orthometric height

常见例句

Ellipsoid height measured by GPS must be transformed into orthometric height so that it can be used to surveying and mapping engineering.
GPS測出的橢球高，必須將其改化爲常用的正高才能用於測繪工程。
This paper introduced the conceptions concerning GPS height system, such as geodetic, orthometric and normal height system and deflection of the vertical.
介紹了與G P S高程系統有關的幾個主要概唸，即大地高系統、正高系統、正常高系統及垂線偏差；
The accuracy of Orthometric Height will be directly affected by ellipsoidal height precision during GPS height transformation, therefore, the detection of gross error is very important.
GPS高程轉換中，大地高的精度將直接影響轉換後正常高的精度，爲此大地高的粗差探測是比較重要的一個環節。
