简单而客观的标准，评估质量的dtm，源自数字等高线，定义。然后将这些标准应用于通过四种不同程序获得的地形模型，这些模型涉及三个以复杂形态设置为特征的样本区域。比较结果表明，每个DTM都受到一种或多种错误或缺陷的影响；然而，一个TIN生成器和一个网格插值器被证明能够有效地产生地形模型，这些模型在很大程度上反映了由输入等高线表示的地面形态。
Simple but objective criteria for evaluating the quality of DTMs, derived from digital contour lines, are defined. Such criteria are then applied to terrain models, obtained by means of four different procedures, which refer to three sample areas characterized by complex morphological settings. The results of the comparison shows that each DTM is affected by one or more types of error or pitfall; however, one TIN generator and one grid interpolator proved to be capable of effectively producing terrain models which largely reflect the ground morphology as expressed by the input contour lines.
