When relevant GIS application system was developed,GIS has always been as centre,the layer of users’requirements was always been ignored,and all the data saved in database of users was brought into GIS.However,many GIS software is too weak to be competent at the complete assignment of database management system.In this case,an unnecessary difficulty was brought for development of system.On the other side,GIS application is limited when all the data were brought into GIS management.In view of existing problem and on analysis of type of users’requirements,the advantage of both information management system and GIS was combined in this paper and three development models of GIS application system were proposed.Moreover,the key technology in this kind of application system was introduced by real cases.
