| 摘 要： | 介绍了在地图缩编中因道路符号所对应的实际尺寸加宽而破坏了建筑物与道路符号的正确关系时,针对第二、三、四类建筑物进行移位所涉及的数学方法,并给出了实验结果。最后,介绍了用栅格探测加矢量计算法对移位后可能产生的要素间的后继图形冲突所进行的探测,以及消除后继冲突的方法。

| Abstract: | This paper discusses the mathematical methods involved in the displacement of the buildings of type 2, 3 and 4 for maintaining the right interrelationships between the street and the nearby building symbols when the ground size of corresponding street symbols are broadened for compilation of maps in smaller scales, and experimental results are given. Finally, a procedure is introduced on the basis of raster detection and vector calculation to detect sequential conflicts after displacement of buildings and a method for removing the sequential conflicts is described. |
