一个新的移动计算的嵌入式GIS模型的研究

针对嵌入式GIS应用在无线互联网络环境下的带宽限制、数据析取量大等问题,采用了移动Agent分布式计算理论与技术,提出了一种新型的移动计算环境的嵌入式GIS模型,分析了该模型中各子模块的主要功能及运行机制,并将该模型应用在某省地震应急指挥系统中,通过离线在GIS客户端工作,可以在线实时发送灾害损失调查信息。实验表明,与传统的分布式计算模型相比较,嵌入了支持移动Agent计算模型的GIS在无线互联网络中具有高效的处理机制和良好的适用性。

Research of a New Embedded GIS Model Based on Mobile Distributed Computing Environment

In view of the narrow bandwidth and large amount of the data-getting of the wireless internet,a new embedded GIS model based on mobile distributed computing environment is further proposed,which adopts the mobile Agent distributed computing theory and technology,analyzed the model of each module main function and operation mechanism,and used the model in a earthquake information system,through off-line in a GIS client,can send real-time online disaster survey information.The results show that embedded GIS with mobile Agent computing model for wireless internet network has highly efficient mechanism for handling and good applicability.
