Mapis not only a graphic description ofspatialinformation,but also an artwork.There are many creative works in a map,such as map design and cartographic generalization.When we read a map,designed and made perfectly,we cane asily get the information we need,furthermore,we can feel the beauty of art.Today,the digital age,GIS is a main tool for spatial analysis.Mapis the best description form of spatial information yet.Geting and updating map data quickly is the key to extending GIS' application field.Cartographic Generalization is indispensable to geting multi-scale map data,whether through remote sensing image or map scanningd igitizing Digital cartographycry for automaticcartographic generalization,Automating cartographic.Generalization has been the botleneck of GIS development.Residential areas on the map as one of the most important factor,Graphics processing is relatively complex.Therefore,reasonable and comprehensive strategy for the appropriate choice of an integrated approach is particularly important.This is a relationship to the combined effect of efficiency,and even the viability of the integrated decision-making process.Residential areas data cartography generalization is a particular case in special element cartography generalization research.The realization of cartography generalization needs follow geography data generalization rules to solve the conflictions caused by reduction of expressive space.Hoverer,special distribution law of residential areas is also an important influence element of cartography Therefore,special element-oriented cartography generalization Is the focus of the GIS research and application.This main work of this dissertationis placed on the research of special element cartographyg eneralization which is sustained by GIS.The author analyses main content and characteristics of the city residential areas data cartography generalization,establishes general projects for different geography elements,adopts Production-Rule methed of artificialin telligence to integrate the synthetical knowledge and synthetical operation,and makes an investigation on synthetical cartography oriented to special geography element of residential area.The dissertation mainly centers on residentiala reas data cartography generalization and research with different levels—theory,method,technique and demonstration.At last,by analysis and evaluation to the experiment dat,as a tisfactoryge neralization result is gained.
