A study on multi-agent spatial database update mechanism based on Wiki idea
Spatial database update is a matter of urgency,which will become the bottleneck to GIS application instead of spatial data production.Hence it has become a focus in GIS research fields.This paper outlines the current spatial database update modes and discusses some related practical issues.In order to shorten spatial database update period and improve the intelligence level of system,an incremental spatial database update mechanism was proposed by using the cooperative work characteristic of Wiki idea and the multi-agent technology in artificial intelligence research field.Emphasis is placed on the construction of spatial database update mechanism.Special resolve method,mechanism elements and data update process are presented in detail.As a practical application,we implement a basic farmland management information system.The results show that this multi-agent spatial database update mechanism based Wiki idea can arouse the interaction of users,shorten the period of spatial data update,improve the use value of data and make the spatial database update more convenient and flexible.So,we suggest that this mechanism can provide reference to help solving the problem of spatial data update.
