A model for point cluster displacement in automated generaligotion

HOU Xuan,WU Fang,LIU Fang,DENG Hong-yan(Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
It is very important to keep the spatial relation of point features during the process of map generalization .But the accuracy,legibility and aesthetic quality of map usually are contradiction,especially in urban region .Displacement is one of the operation to spatial conflicts solution in the process of cartographic generalization.Sequential methods being used on automated displacement have a long tradition.But this type of approaches can't solve all conflict and,further,they can't compromise between cartographic constraints.Optimization algorithms were only recently introduced to the field of cartographic generalization.The Finite Method is a standard optimization method in engineering science.We suggest a beam model based on the finite method for the displacement of buildings.
