With the deeply application of GIS in agricultural sector,the development of agriculture GIS application system is moving in the specific,complex and specialized.Aiming at the existed shortages of the current agricultural GIS application system,such as lack of unification among conceptual model,data model,metadata standards,limitation of database integration,by analyzing the MDA framework and development process,combined with software reuse ideas and the MDA approach,this paper proposed a MDA-based development mode for building agricultural GIS applications,and described some key technologies for spatial database model construction.With examples,it also discussed the feasibility,advantages and disadvantages in constructing agricultural GIS application system based on MDA method.
