以我国东部平原地区钱营孜煤矿矿区为案例,根据实测的散乱数据,使用交叉统计检验和视觉特征分析了ANUDEM方法和与地理信息系统领域中常用传统插值方法的空间插值结果。分析表明,在平原地区,TIN方法生成的DEM具有较高的精度,ANUDEM方法生成的DEM能够准确反映水文地貌。 更多还原
【Abstract】 A case study is given at the area of Qian Yingzi coal mine in China’s eastern plains,which compared and analyzed the spatial interpolation results from the method of ANUDEM with those from GIS conventional interpolation methods for interpolation of spatially measured scattered data.This paper used statistical cross-validation and visual characteristics method to compare interpolation results from different methods.Comparisons showed that,in the plains,the DEM which was generated by TIN had highe... 更多还原
