充分利用Surfer软件强大的插值功能和绘制图件能力，分析了其在GPS高程拟合中的应用，一是基于Surfer所显示的高程异常三维表面显示图的起伏情况，分区域选择最能表达地形的数学模型，使得高程拟合达到最佳效果；二是对离散点的高程异常进行内插计算，获得一定间隔的格网高程异常模型，根据该模型内插待求G PS点的高程异常，从而将G PS大地高转换为正常高。通过实验分析了此两种应用的可行性。

Taking full advantage of surfer software with great interpolation function and graphic capability ,this paper analyses application of height fitting .The first is the investiga-tion of ups and downs of 3D surface map of height anomaly based on surfer software ,selec-ting the best mathematical model regionally ,and making the best effect of height fitting . The second is interpolation calculation of height anomaly of discrete points ,in order to get grid of height fitting model with space ,and interpolate height anomaly of unknown points , then completes height transform .It makes a simple analysis by experiment .
