【摘要】 本文提出了城市地质信息系统的总体结构,系统划分为数据层、应用层和服务层三个层次。由信息数据录入与管理子系统、三维地质体建模子系统、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,并说明了高精度三维地质模型快速构建、大数据量模型运行和多元数据一体化显示这三个关键技术的解决方案。更多还原

【Abstract】 In this paper,the architecture of Urban Geological Information System is presented.This system is divided into three levels of data layer,application layer and service layer,and composed of three sub- systems of data input and management subsystem,three-dimensional geological body modeling subsystem, data sharing and socialized services subsystem.The development plan of this system is expatiated in the sections of database and application system.The solutions of the three key technologies,namely,the high precision three-dimensional geological modeling,operation of the model with gigantic data quantity,integra- tive display of multi-source data,are explained in this paper.更多还原
