摘　　要：根据长白山无人区1∶10 000像片控制测量实例,说明利用GPS测量速度快、点间无须通视、迁站方便、测量大地高相对精度较高的特点。采用GPS高程拟合方法,通过高程异常值求解像片控制点的正常高,解决了山区像片控制点的高程测量难题。According to Changbai Mountain area 1：10 000 photo control survey in this paper. Illustrate that GPS survey speed, without having to pass between points, easy to move station, high precision in measure geodetic height. Using GPS elevation fitting method, solving the photo normal elevation by abnormal elevation value, to solve the problem of survey photo control points in the mountains.
