orthometric height

常見例句

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，必須將其改化為常用的正高才能用于測繪工程。
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(tǒng)有關的幾個主要概念，即大地高系統(tǒng)、正高系統(tǒng)、正常高系統(tǒng)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后正常高的精度，為此大地高的粗差探測是比較重要的一個環(huán)節(jié)。
