传统标绘系统都是单用户工作模式,不能满足现代社会中群体用户在分布式环境下协同标绘的要求。本文将网格技术引入分布式实时协同标绘研究中,设计了基于网格的分布式实时协同标绘系统的框架,介绍了其系统框架,以及协同管理、协同消息、网格调度器等技术。将网格和GIS技术的结合,实现了分布式实时协同符号标绘系统原型,满足群体用户的地理信息共同协调与合作标绘的要求。实验表明,以网格技术构建分布式实时协同绘系统,能实现广域网下的快速协同,使其响应速度快,稳定性好。 更多还原

【Abstract】 With the rapid development of computer network technologies and distributed computing technologies,common collaboration and cooperation based on geospatial information for team users are increasingly popular.Since the traditional plotting system is single-user mode that is not able to meet the requirement of collaborative plotting of group users in modern society in a distributed environment,in this paper we focused on establishing a distributed real-time collaborative plotting system with grid ... 更多还原
