Paper Abstract

As a new research direction, collaborative virtual geographic environment (CVGE) offers an intuitively and efficiently interactive visualization environment. The environment allows geographically separated users to explore complicated spatial information and conduct collaborative work. Data collaboration plays a very important role in the CVGE because geographic data is its basic support. Data collaboration can support multi-directional sharing of data and files, allowing ideas and thoughts to be communicated interactively among CVGE attendees. In this paper, we firstly analyses the main characteristic of the CVGE data and some problems in data collaboration. Based on Multi Agent System (MAS) technology, then we design a cooperative data function model, which aims to integrate all data and databases in the CVGE and form a virtual uniform database. Some key problems such as concurrency control, distributed system architecture and the algorithm of creating dynamic group are also introduced. Finally, an example is given and the experiment result shows that the scheme addressed in the paper is efficient and feasible.
