摘要
文中介绍了基于线要素的图幅自动接边的基本算法 ,主要分 3步完成 :待拼接数据链的提取 ,属性匹配和图形拼接 ,给出了具体的实现过程 ,并应用某区的地貌数据进行了实际检验。
The basic algorithms of automatic adjoining sheets on line primitives are introduced. There are three main steps to complete: the extraction of waiting for adjoining data chain, attribute matching and map sheets adjoining. The specific achievement process is given and it is tested by the geomorphic data of the region. Furthermore, the topological adjoining of the road feature between map sheets in traffic information manage system is studied.
