基于移动Agent的分布式地理信息检索系统研究

摘要

How to find the information of the user 's interest accurately and quickly from the vast amount of spatial information is the main problem to be solved.To this end, a distributed geographic information retrieval framework based on mobile Agent is proposed , and the key technologies are studied .The introduction of mobile Agent technology makes the space more intelligent retrieval .It can ef-fectively solve the problem of network bandwidth , computing the offline , and greatly improves the retrieval efficiency , provides a new way of thinking and solving method for the construction of distributed GIS system .%如何从海量的空间信息中快速准确地找出用户感兴趣的信息,是地理信息空间检索服务所要解决的主要问题.为此,本文提出了一种基于移动Agent的分布式地理信息检索框架,并对其中的关键技术进行了研究.移动Agent技术的引入使得空间检索更加智能化,能有效解决网络带宽问题和离线计算问题,同时极大地提高了检索效率,为分布式GIS系统建设提供了一种新的思路和解决方法.
