摘要
The essentiality, history and current status of urban geological informationization were analyzed. This system was divided into three levels of data layer, application layer and service layer. In terms of functions, it was constituted of three sub-systems of data input and management sub system, data analysis and evaluation sub system and data sharing and socialized service sub system. The development plan of the system was depicted in the sections of database and application system. Also the key solutions of the 3D high precision geological modeling, integrative display of multivariated data, and professional geological analysis and evaluation architecture were explained in the paper. Finallay, the application of the design above in the deployment of Hangzhou urban geological information management and service system was presented.
