| 摘 要： | 针对常用的空间插值方法在精度分析方面比较的不足，从地质统计学、数学函数和几何方法方面分别选取普通克里金插值法、三次样条函数法和距离权重倒数法进行插值精度的比较与分析。文章分析了各个方法的优缺点和局限性，选取疏密差异较大的均匀和不均匀离散点数据进行实验，利用三次趋势面模型和MATLAB，ArcGIS，GS+Version...

| Abstract: | Aiming at the comparative lack of precision anolysis of the interpolation methodscommonly used in the spatial analysis,Ordinary kriging,three splines for special interpolation and inverse distance weighted were compared and analyzed through Geo-statistics,mathematical function and geometric method.According to advantages and disadvantages with the limitations of the three methods,the uniform discrete point sets and the non-uniform discrete point sets were selected for comparison.The cubic trend surface mode... |
