摘要
本文介绍了分布式地理信息系统(DKGIS)的设计和实现。其中提出了以对象为中心的关系-框架数据模型,新型的物理数据结构。系统采用先进的分布策略,很好地实现了数据的分布查询和更新;DKGIS具有以知识和模型为基础的辅助决策功能和友好的自适应人机接口.测试表明,该系统功能齐全,智能水平高,分布能力强,使用方便.
In this paper the design and implementation of knowledge based geographic information system are discussed. An object oriented relation frame semantic data model and new physical data structure are proposed. In the system advanced distributed tactics is used to implement data distributed query and update between different nodes. Also the system possesses the functions of the computer aided decision based on knowledge and models and the friendly adaptive human computer interface. The test shows that the system has the advantages, such as high intelligence, good distributed functions and convenient for use.
