Design and Implementation of Distributed Virtual Geographic Environment System based on MAS

摘要

The use of distributed virtual geographic environments (DVGE) is one of the most promising uses of virtual reality in geographic field. Multi-Agent Systems (MAS) is flexible and adaptive enough to resolve highly complex distributed computing problems. This paper aims to discuss how to apply MAS technology to improve the efficiency of collaborative work among multi-user. We firstly design the three-layer system architecture and multi agent system of the DVGE. Then dynamic cooperative group algorithm is also addressed. Finally, we built a collaborative virtual environment and implemented prototype system in silt dams system planning on a case study area, Jiu-Yuan-Gou watershed of Loess Plateau, China. Experiment results prove that the scheme addressed in this paper is efficient and feasible.
