中文摘要：
高程异常一般呈复杂的不规则曲面,多面函数法利用多个曲面叠加可较好地从整体上逼近高程异常,但其无法准确反映高程异常的局部性变化;Shepard插值虽对高程异常的整体插值效果不理想,却可以很好地体现其局部相关性。本文结合两者特点,提出了基于多面函数与Shepard插值的高程异常综合拟合法,取得了满意的拟合效果。
英文摘要：
Height anomaly is generally represented by a complex irregular surface,and it can be well overall fitted by multi-quadratic model.But the model can’t accurately reflect the locality of changes of height anomaly.Meanwhile,though the overall interpolation result of Shepard interpolation may be not satisfied,it can be a good reflection of height anomaly’s local relevance.In this paper,a synthetic method is created which combines advantages of the multi-quadratic model and Shepard interpolation,and it achieves an ideal fit precision.
