Mathematical Methods Involved in Constrained Reshaping for Solving Graphic Conflicts Between Streets and Buildings
-
摘要: 在新型辅助栅-矢混合数据结构以及自动建筑物分类的基础上,介绍了在地图缩编中因周围多条道路符号加宽而无法通过移位来维持建筑物与道路符号的正确关系时必须采取的建筑物受限变形所涉及的数学原则,给出了实验结果,并用目视法和数字法对变形结果作了评价与分析。Abstract: On the basis of the new auxiliary hybrid raster-vector data structure and automatic building classification introduced in the previous paper,the mathematical methods involved in the constrained reshaping of the buildings are discussed for maintaining the correct innerrelationships of the buildings,and the right interrelationships between the street and the nearby building symbols,when the multi nearby street symbols are broadened for compilation of maps in smaller scales,and there is no more place for ordinary displacement.The experimental results are shown and their evaluations are given from the aspects of visual and digital analyses.
