保持弯曲特征的线要素化简算法
The Line Feature Simplification Algorithm Preserving Curve Bend Feature
摘要
Abstract
Line feature generalization has been an important part of map generalization, of which the linear elements simplification is the most important part. Based on the analysis of the related literature about the simplifi-cation of the linear elements, a curve bend feature line simplification algorithm was proposed. With the quantifica-tion of the constraint conditions in the bend selection process, linear element was simplified and its visual bend was maintained, which help to describe the changes accurately before and after the bend simplification. Through the ex-perimental test, this simplification method has achieved a good result.关键词
