Theory and Technique Model of Automated Cartographic Generalization Chain

It is a puzzle for long time that how to improve the level of cartographic generalization.In order to meet with the exigent requirement to cartographic generalization in cartography and GIS,new theory,method and model should be created.After analyzing current research and problems of cartographic generalization,this paper created automated cartographic generalization chain(ACGC) theory and technique fully.It translated abstract cartographic generalization course into realizable cartographic generalization tasks,then transformed the tasks into ACGC,which could be executed and optimized by computer automatically.Thus the automatization and intelligence level of cartographic generalization were improved.Experiments illustrate that the theory and technique of ACGC based on knowledge is useful and innovative.It is an important creation in the field of cartographic generalization,which affects the theoretic building and improves automatization level of cartographic generalization directly.
