空间分析中几种插值方法的比较

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IDW15.75IDW2.1d-01≤还s7IDWOKFig 5 Elevation distribution of aTab2 Comparison of the uniformmine areadiscrete point sets in interpolation error6 OKSt VersionFig 6 Semi-variance curve and elevationpoints value chart of OKC0=4950C0+C=1254019225517895113056A0-453R2-0.9126 aGS+ Version ArcGIs122.194536263468OK TSIDW326967514448191.806E】1313-31.12856567b-29ad ok 3b ts 3C IDw 37 OK TS IDW3Fig7 OK, TS, IDW Three-dimensional interpolation effectWGWNWww.Gwn.Org.Cn206 No. 3 GEOMATICS WORLD43o1994-2011ChinaAcademicJournalElectronicPublishinghoUse.Allrightsreservedhttp://www.cnki.net2.33 DW33dri=o3.13l≤r≤I OKIDWLoins
