在数字地形建模中,TIN能够更加真实地反映地形信息,但由于TIN在数据结构和数据组织上的复杂性,采用通常的数字高程模型质量评价方法是不完善的。文中列出了3维空间中TIN的几种质量影响因素,分析了各因素对TIN的质量的作用和影响,并基于权重设计了一种根据质量影响因素评价TIN的质量的方法。 更多还原

【Abstract】 TIN can reflect the information of terrain more opportunely in DTM,however,because of the complexity of data structure and data organization,it is not suitable to evaluate TIN using general DTM quality evaluating quality of 3-Dimensional TIN are specified in this paper,and each of them is expounded how it works.A method of quality evaluation for TIN is designed according to the quality affecting factors based on weighted theory. 更多还原
