摘要
由于Internet网络带宽限制等诸多方面的影响,基于GIS的分布式实时协同制图系统是较难实现的。采用复制式 模型构造了一个基于GIS的分布式实时协同制图系统,并且采用动态数据格式作为各站点的交换数据,极大限度地减少 了网络数据传榆量,提高了系统的响应速度和稳定性,满足了协同制图系统对实时性的要求。
It is hard to carry out the distributed real-time collaborative cartography system based on GIS due to the limitation of network bandwidth and some other reasons over internet. A distributed real-time collaborative cartography system based on GIS is constructed with reproduce model and dynamic data format is adopted as exchange data in every workstation. It greatly reduces the load of network, enhances capacity of rapid response and stability of the system and meets the real-time requirement of collaborative cartography system.
