基于Agent技术的多层分布式GIS研究

Agent-based multi-layer distributed GIS

对实现分布式GIS所存在的问题进行研究,分析和应用了多层体系结构和Agent技术各自的优点,提出了基于Agent技术的多层分布式GIS体系结构,并通过编程所进行的原型实验证明基于Agent技术的多层分布式GIS体系结构在实现分布式GIS时的可行性,从而解决了传统GIS体系结构无法解决的互操作性、资源(包括功能和数据)的迁移、资源的分散管理和集中管理、多服务站点协同工作等问题.

A study is made on some existing problems with the realization of distributed GIS. By analysis of the advantages of the multilayer system structure and Agent technology and their applications, a multilayer distributed GIS structure is developed based on the Agent technology. The prototype test, performed by compilation of corresponding programs, indicates that the structure can realize the interoperation, transfer and decentralized and centralized management of resources (including functions and data), and cooperation between servers, which could not be realized by the conventional GIS structure, verifying the feasibility of realization of distributed GIS by the present GIS structure.
