orthometric height

基本解釋

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(wèi)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(tǒng)有關(guān)的幾個(gè)主要概唸，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(zhuǎn)換中，大地高的精度將直接影響轉(zhuǎn)換後正常高的精度，爲(wèi)此大地高的粗差探測是比較重要的一個(gè)環(huán)節(jié)。

正高
If the Geoid or quasi-Geoid model is given, GPS can be used directly to determine orthometric height or normal height, which can take the place of the traditional geometric leveling and make the separation mode of plane control network and elevation control network in traditional geodesy become a history.
在高精度、高分辨率(似)大地水準(zhǔn)麪模型的支持下,利用GPS技術(shù)可以直接測定正高或正常高,從而取代傳統(tǒng)繁瑣的水準(zhǔn)測量方法,使得平麪控制網(wǎng)和高程控制網(wǎng)分離的傳統(tǒng)大地測量模式成爲(wèi)歷史。
