基于GIS的区域地质调查信息系统设计与建立

Design and Formation of Information Database System in Area Geological Survey on GIS

针对区域地质调查数据管理的具体要求和目标,分析了该信息系统的系统需求,阐述了基于COM组件技术的区域地质调查数据库的建立方法,利用关系型数据库SQLServer建立空间数据库和属性数据库,实现空间数据和属性数据一体化管理,在Delphi编程环境下采用MapObjects控件开发系统用户界面,并对系统数据库、结构和主要模块的功能进行总体设计。

Being aimed at the request of the management of the information data in area geological survey. System requirements of information system are analysed. It describes in detail the methods of the formation of information database system in area geological survey based on COM technology. The database holding the spacial data and property data has been established in SQLServer. By managing spacial and property data of the GIS in area geological survey, comprehensive management of these data is achieved. With Delphi and MapObjects the user-interface of campus geographical information system is developped. The database system, structure, function of the main module are also designed.
