基于自由空间重力异常的格网化方法比较

Comparison of gridding methods for free-air gravity anomaly

针对目前常用的4种格网化方法,结合航空重力测量成果和重力场理论模型计算结果,对比分析4种方法的优劣,提出利用反距离加权平均法进行离散点的格网化处理,可获取更理想的内插效果,为解决离散点从点到面的应用提供一种思路。

Aiming at the commonly used four grid handling methods,combination of airborne gravity measurement results and the gravity field model calculation results,analysis of the merits of the four methods,put forward using inverse distance weighting method to discrete points of grid handling can obtain better interpolation effect,in order to solve the application of the discrete points from point to surface to provide a train of thought.
