| 摘 要： | 数字高程模型(DEM)是对实际地面模拟的一种有效方式,它的数据来源于实地测量,由于客观条件的限制,实地测量数据是一种抽样数据,样本密度影响了数字高程模型的精密度。针对这一问题,探讨了运用克里金法对数据样本进行插值处理的算法,将样本进行加密,从而提高数字高程模型的适应度,满足不同的需求。

| Abstract: | DEM is an effective method for simulate the real terrain,its data root in the survey.Limited by the object condition,the survey data is sampled data,the sample density affects the accuracy of DEM.To this question,the arithmetic of sampled data interpolation by Kriging was discussed,the arithmetic was used to produce the detail sampled data,and then the adaptability of DEM was improved to satisfy the different requirement. |
