杭州市城市三维地质信息管理与服务系统的构建

分析了城市地质信息化的必要性、发展历史及现状。提出了城市地质信息系统的总体结构,系统划分为数据层、应用层和服务层3个层次。在功能上则由信息数据录入与管理子系统、地质数据分析评价子系统、数据共享与社会化服务子系统构成。然后分数据库和业务应用系统两个部分阐述了系统的开发方案,并说明了三维地质结构建模、多元数据一体化显示和专业分析评价这3个关键技术的解决方案。最后给出了所述思想在杭州城市地质信息管理与服务系统开发中的应用情况。

Construction of urban three dimensional geological information management and service system of Hangzhou City

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 text. Finallay, the application of the design above in the deployment of Hangzhou urban geological information management and service system was presented.
