Agent-based multi-layer distributed GIS

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.
