| Abstract: | In this paper,the metadata,data and database of geodetic survey are analyzed synthetically.Based on UML,the method model of metadata to data meaning expression and dynamic query in geodetic database are presented.The access model of the geodetic metadata,and the alternation model in the application layer which is correspond to the geodetic operation logic of the geodetic sharing platform's serving mechanism and the interaction flow based on the web are discussed in the paper. |
