| Abstract: | Considering to the traits of WebGIS architecture in distribution, dynamics, heterogeneity and legacy and the merits of mobile Agent in distributed computing, mobile Agent is applied to WebGIS. A mobile Agent-based WebGIS multi-layer architecture service request model is presented, and the dynamic architecture model is formalized by process calculus. The effectiveness, correctness, usability, reliability and rationality of the model have been proved by logical deductions. The functional integration is realized, and a dynamic cross-platform GIS system with multi-space information is constructed. The efficiency of the distributed GIS application system is improved, and the range of its application is expanded. |
