1大地坐标设置椭球参数 2投影坐标设置投影参数 3基准转换设置不同椭球转换三参数
系统没有CGCS2000到WGS84的基准转换我们增加CGCS2000至WGS84的基准转换
先找到CGCS2000的椭球和WGS84椭球
然后利用WKT文件新建基准转换
先拷贝一个WKT比如ITRF_2000_To_WGS_1984
GEOGTRAN[ITRF_2000_To_WGS_1984,GEOGCS[GCS_ITRF_2000,DATUM[D_ITRF_2000,SPHEROID[GRS_1980,6378137.0,298.257222101]],PRIMEM[Greenwich,0.0],UNIT[Degree,0.0174532925199433]],GEOGCS[GCS_WGS_1984,DATUM[D_WGS_1984,SPHEROID[WGS_1984,6378137.0,298.257223563]],PRIMEM[Greenwich,0.0],UNIT[Degree,0.0174532925199433]],METHOD[Geocentric_Translation],PARAMETER[X_Axis_Translation,0.0],PARAMETER[Y_Axis_Translation,0.0],PARAMETER[Z_Axis_Translation,0.0],AUTHORITY[Esri,108280]]
改成CGCS_2000_To_WGS_1984
GEOGTRAN[CGCS_2000_To_WGS_1984,GEOGCS[GCS_China_Geodetic_Coordinate_System_2000,DATUM[D_China_2000,SPHEROID[CGCS2000,6378137.0,298.257222101]],PRIMEM[Greenwich,0.0],UNIT[Degree,0.0174532925199433]],GEOGCS[GCS_WGS_1984,DATUM[D_WGS_1984,SPHEROID[WGS_1984,6378137.0,298.257223563]],PRIMEM[Greenwich,0.0],UNIT[Degree,0.0174532925199433]],METHOD[Geocentric_Translation],PARAMETER[X_Axis_Translation,0.0],PARAMETER[Y_Axis_Translation,0.0],PARAMETER[Z_Axis_Translation,0.0],AUTHORITY[Petrel,78280]]
X_Axis_TranslationY_Axis_TranslationZ_Axis_Translation即是基准转换三参数
4建立Petrel项目所能识别搜索的坐标系统 5新建Petrel项目选择GS120E坐标系统 参考文献
