| 摘 要： | 简要介绍了标准克里格法和泛克里格法进行高程拟合的理论和方法,以实例验证了标准克里格和泛克里格法在小区域GPS高程拟合的效果.研究结果表明,如果选择合适的变异函数模型,泛克里格法能明显提高拟合精度,且具有拟合残差振荡小、变化平缓等优点.

| Abstract: | In this paper,Kriging technology and its application in GPS height fitting field were briefly discussed.The performance of GPS height anomaly fitting in small area was proved in an experiment by using standard Kriging and extensive Kriging technology.Preliminary results showed that if the appropriate semi-variation function model was selected,the accuracy of GPS height anomaly fitting can be obviously improved.What’s more,the proposed method has the advantages of smaller fitting residual?oscillation and smoother change. |
