摘要
通过对大地测量元数据、数据、数据库进行综合分析,基于UML提出了元数据对数据进行语义表达和动态索引的方法模型,讨论了大地测量元数据的存取模型,在应用层面上对大地测量元数据的服务机制和基于Web的交互流程提出了符合大地测量业务逻辑的交互模型.
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.
