摘要
分析讨论空间数据内插中反距离加权法和谢别德法的基本原理,并利用SRTM数据对算法进行测试。结果表明:改进谢别德法的插值效果优于反距离加权法和原始谢别德法。
IDW and Shepard algorithms for spatial data interpolation are introduced in this paper.The test result shows that the modified Sheppard method has more advantage than the IDW method and original Sheppard based on the SRTM data.
