Based on the analysis of the development of GIS technology and application,this paper brought forward the concept of GoGIS,namely Cooperative GIS ,CoGIS is GIS facing group-users and supporting human-human interaction,which makes it differ from the former GISs,Then,the characteristics of general Computer Spport Cooperative Work (CSCW)applications and the complexity of Geographic Information Science were analyzed,and the conclusion the CoGIS was not a simple GIS layer on CSCW was reached,Further,this paper gaver the hierarchical architecture of CoGIS,and analyzed the coperative platform in detail from the following:1)basic elements;2) collaboration patterns;3) cooperation control mechanism;4) synchronization mechanism;5) security and 6) group communication and so on.With those,the problems about GIS applications are discussed,such as 1)distributed multi-source GIS information and knowledge sharing platform;2)the fusion and visualization of GIS information;3)virtual reality cooperative modeling;4) dymamic simulation;5)expert system and 6) decision-making.Finally,this paper analyzed CoGIS application mode in brief. 相似文献

协同GIS软件体系结构研究 总被引:6,自引:0,他引:6
分布式的异构地学信息处理与分析,需有支持协同工作的GIS平台。但是现有的GIS基础平台大都只具有部分协同功能,真正意义上的协同GIS基础平台尚未出现。本文结合计算机支持协同工作的相关理论,提出协同GIS的体系结构,分析了协同逻辑在协同GIS体系结构中各部分的特征和作用,并论述了所涉及的研究内容。 相似文献
