我有一景ETM+数据,导入ERDAS后不知如何投影成高斯-克吕格（BJ54）坐标系统中去。
我也作了一些尝试：
 将原投影设置为：
 1.projection type:Space oblique mercator
 2.spheroid name:WGS84
 3.datum name:WGS84
 4.landsat vehicle ID:0
 5.path number:0
 6.false easting:0
 7.false northing:0
 目标投影设置为：
 1.projection type:Gauss Kruger
 2.spheroid name:krasovsky
 3.datum name:krasovsky
 4.longitude of central meridian: 117:00:00.000000 E
 5.latitude of origin of projection: 0:00:00.000000 N
 6.false easting: 500000.000000 meters
 7.false northing: 0.000000 meters
用上述参数投影的结果并不正确。
敬请各位指导。
