摘要： 本文首先阐述了图斑概括过程中应遵循的原则,即正确处理几何精确性与地理真实性、清晰性和详细性两对矛盾,继而提出了自动化制图综合的设计策略。然后探讨了非连续分布面状地理现象(即图斑)的自动取舍、化简、夸大和移位、以及合并等算法,介绍了上述算法的实现方法,并给出几种地物图形自动概括的应用技术流程。

Abstract: In this paper,some principles of automated generalization on the discontinous area phenomena-were discussed,followed by the strategies of auto-generalization.Furthermore,the authors expounded the algorithms of every operation of the figure auto-generalizatio of areapatch,i.e.,selection/elimination,simplification,exaggeration,displacement,and aggregation.Finally,the implementation methods of the above algorithms,and the operational workflows of a few cartographic feature,were reported.

Key words: Area phenomena, Generalzation, Figure Auto-gneralization
