Abstract:Toachievetheconversionbetween thelocalindependentcoordinatesystemandtheChina GeodeticCoordinate System200o(CGCS20),thispaperdiscussesusingthecoordinatesofcommonpointsandHGOsoftware tosolvetheprojection parametersandBursasevenparametersofthelocalindependentcoordinatesystem,aswellasusing HGOsoftwareandBursa sevenparameters toconductcordinate conversion between thelocalindependentcoordinatesystemand China Geodetic Coordinate System 2O0o (CGCS2OoO),and verifies the accuracy of coordinate conversion.

自從全面啟用2000國(guó)家大地坐標(biāo)系以來(lái),我們?cè)趯?shí)際測(cè)繪工作中經(jīng)常遇到坐標(biāo)轉(zhuǎn)換的問(wèn)題,在沒(méi)有CORS系統(tǒng)、GPS接收機(jī)輔助的情況下如何進(jìn)行坐標(biāo)轉(zhuǎn)換?轉(zhuǎn)換的精度能否達(dá)到項(xiàng)目質(zhì)量要求?本文主要論述利用HGO軟件和公共點(diǎn)坐標(biāo)求解: ① 獨(dú)立坐標(biāo)系的投影參數(shù); ② 布爾莎七參數(shù); ③ 獨(dú)立坐標(biāo)系和2000國(guó)家大地坐標(biāo)系坐標(biāo)轉(zhuǎn)換。(剩余5362字)
