拓扑编码 meaning in English
topological coding
Examples
- The paper would make a study of construction data frame of large - scale ugis in order to make a sound theoretical ground of the construction of digital city . in the paper , the author brought forward firstly of scheme of topologic coding on ugis classification and coding based on streets and administrative districts according to the existing national standards of ugis classification and coding and corresponding digital city " methods of classification and coding
在参照国家现有的城市地理信息分类与编码标准和相应的数字城市分类与编码方案的基础上，针对大比例尺城市地理信息系统对城市地理信息分类与编码的要求，作者首创性的提出了绑定式的城市地理信息分类体系与拓扑编码方案。 - In the scheme , ugis classification and coding are divided into three steps : administrative districts are firstly classified and coded , and then street and road with the corresponding code of administrative district added , at last add the code of both the corresponding administrative district and street or road into the code of other corresponding geo - information . this method can reflect topologic relationship between objects , make a fast query and shorten the length of codes
这种绑定式的城市地理信息拓扑编码的好处是：在编码中既体现了城市地理信息之间在空间上的拓扑关系，又提高了整个系统查询和检索的速度；按行政区划和城市街道进行城市地理信息的分类与编码，代码结构清晰易懂，而且可以大大缩短编码的长度。
