Research on cooperative distributed geographic modeling control pattern based on Holon

The cooperative distributed geographic modeling has become a hotspot of Geographic Information Systems (GIS) research field. This paper introduces the architecture of the Cooperative Distributed Geographic Modeling (CDGM) control pattern based on Holon, studies the distributed control on the existing spatial data and the geographic models, which are gotten from different regions and belong to different institutes. The CDGM control pattern can lead to higher efficiency in solving complex geographic problems. Also it designs the architecture of cooperative distributed geographic modeling control pattern based on Holon for geographic problem resolving. Finally, a prototype system is implemented for cooperative distributed geographic modeling on Soil and Water Assessment Tool (SWAT). Moreover, the experimental results have verified such a cooperative distributed geographic modeling control pattern based on Holon is efficient and feasible.
