摘要
通过对协同GIS的发展状况和所面临的问题的分析,提出了基于任务组管理机制的协同GIS工作模型和面向协同GIS特征的空间数据模型(OCFSDM),重点讨论了它们的组织结构及设计思路;对同步/异步协同编辑过程进行了分析并给出了解决方案。最后,借助于CORBA分布式计算技术和数据库技术,构建了基于上述模型的协同GIS原型系统,给出了系统的测试情况;测试结果表明,系统达到了设计目标。
The development and some existing problems of CoGIS were discussed. By analyzing the process of coordinated map-editing, a CoGIS cooperative work model was put forward based on work groups and oriented collaborative feature spatial data mode （OCFSDM）. The structure of CoGIS model and OCFSDM were discussed and analyzed. Finally, the flow of cooperative map-editing was discussed based on CORBA and database technology. The prototype test system was developed. From the result, the conclusion indicates that the test system has reached the aim of the design.
