This paper focuses on a new method approach for use Multi-Agent to implement spatial analysis. Firstly, we give a model to implement spatial analysis through cooperative work. Secondly, we explain the communication, cooperation and architecture of Multi-Agent based Spatial Analysis. At last, we give a prototype system.
