Abstract: The realization of distributed geographic models sharing may strengthen the functions of GIS analysis,forecasting,decision-making and so on.But the existing distributed geography model resources have not yet realized global sharing.With the rapid development of information technology,the geographic model sharing via Internet has become not only possible,but also essential.We analyzed the present situation and existing problems in geographic models sharing and introduced a new method for distributed geographic models sharing based on Web Services,which is provided to locate,share,and publish model sources.We also defined Web Services for geographic models and its corresponding service framework,and service system in order to overcome the obstacles of model resources derived from the distributed environment.We constructed geographic models sharing gateway as a confirming platform.Experiments proved that the method for distributed geographic models sharing proposed here is practical and feasible based on Web Services.A user can locate,access,and retrieve all geographic models available in the architecture in an easy,flexible,and agile way through Web Services.
