Abstract: Urban residential regions are important parts of the urban living environment,and they are closely related to urban life.In order to meet the demands of comprehensive analysis and simulation of urban environments,this paper combines the concept of virtual scene and integrated modeling in the virtual geographic environment (VGE)to design a data organization method for constructing urban residential region for modeling.Through the abstraction of system,object and relation,the complex environment information of an urban residential region can be described and organized in a hierarchical structure.In addition,the universal data description and eXchange model (UDX)was also employed to describe and store the data content for urban residential regions in a uniform manner.The data content that meets the demands of a geo-analysis model can be extracted from the modeling scene,thus supporting the integration of different geo-analysis models and the modeling scene.The experimental results show that the proposed method can effectively organize the heterogeneous urban environment data and provide the demanded modeling data conveniently for the geo-analysis models from different research areas.

Key words: urban residential region, geo-analysis and simulation, modeling scene, virtual geographic environments
