常見例句雙語例句Ellipsoid height measured by GPS must be transformed into orthometric height so that it can be used to surveying and mapping engineering.GPS測(cè)出的橢球高,必須將其改化爲(wèi)常用的正高才能用於測(cè)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(cè)是比較重要的一個(gè)環(huán)節(jié)。 返回 orthometric height
