用RTK作業(yè)時(shí),在54坐標(biāo)系采集的經(jīng)緯度坐標(biāo),和在80等坐標(biāo)系下采集的同一個(gè)點(diǎn)的經(jīng)緯度坐標(biāo)是一樣的么?
還有 這個(gè)點(diǎn)的經(jīng)緯度 是WGS84坐標(biāo)下的么？我做了個(gè)實(shí)驗(yàn)，同一個(gè)點(diǎn)，在54 80 84下都采集了，經(jīng)緯度坐標(biāo)在小數(shù)點(diǎn)后8位才有變化PT1,36.3958133442,117.0330183652,55.426,00000000

這些經(jīng)緯度是原始的RTK文件轉(zhuǎn)化來的，看起來沒多少變化，換算成平面位置，變化很小，都在RTK精度范圍內(nèi)，我想 RTK測量的原始數(shù)據(jù)，就是經(jīng)緯度，不管你要轉(zhuǎn)成什么坐標(biāo)系，原始數(shù)據(jù)都是一樣的，對(duì)不？
