数字测绘产品质量要求第1部分:数字线划地形图数字高程模型质量要求 - Two kinds of multi - resolution spatial data model are studied in this paper . one is the feature model and hoom model based on dlg data . the other is multi - resolution dem model based on terrain data using the algorithms of self - adaptive triangular regular networks and hierarchical triangular irregular networks
论文主要对两种类型的多分辨率空间数据模型理论和实现技术进行研究，第一类空间数据是数字线划图数据dlg ，第二类是数字高程模型数据dem 。 - This paper uses digital line graphs for original data . after author bases on large - scale relief map " feature and analyses the feature , data structure and creation algorithms of two main representation shape ? triangulated irregular network and regular grid , author provides a kind of method that large - scale dem is created from tin which is created from large - scale dlg
本文以数字线化图为原始数据，针对大比例地形图的特点，在分析了数字高程模型的两种主要表现形式? ?不规则三角网tin和规则格网grid的特点、数据结构、生成算法的基础上，考虑到大比例尺数字高程模型能最大限度符合实际地形特点，提出了一种从大比例尺数字线化图dlg生成不规则三角网tin ，再由不规则三角网内插生成大比例尺数字高程模型grid的方法。
