摘要: 本文介紹了分布式地理信息系統(tǒng)(DKGIS)的設(shè)計(jì)和實(shí)現(xiàn)。其中提出了以對象為中心的關(guān)系-框架數(shù)據(jù)模型,新型的物理數(shù)據(jù)結(jié)構(gòu)。系統(tǒng)采用先進(jìn)的分布策略,很好地實(shí)現(xiàn)了數(shù)據(jù)的分布查詢和更新;DKGIS具有以知識(shí)和模型為基礎(chǔ)的輔助決策功能和友好的自適應(yīng)人機(jī)接口.測試表明,該系統(tǒng)功能齊全,智能水平高,分布能力強(qiáng),使用方便.Abstract: 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.
