摘要: 针对现有空间插值方法局部保形性差、边界处理困难等问题,利用Voronoi空间剖分的结构特性,提出了一种多维统一的局部保形空间插值算法。利用随机模拟数据及中国城市平均气温数据进行了实例验证,结果显示,本插值算法可支撑不规则边界数据,在兼顾精度的同时,具有很好的局部保形性。Abstract: The previous spatial interpolation methods have problems on the keeping of local structure and boundary treatment.To overcome these problems,based on the structural properties of the Voronoi on spatial partition,we propose a multi-dimensional unified spatial interpolation algorithm.With random simulated data and the average temperature data of Chinese cities,the experimental results indicate that the proposed interpolation algorithm can support irregular boundary data,and achieve good performance on keeping local structure characteristics and high accuracy.
