Abstract: Research on organization mode of satellite quality evaluation module is the key of mining and using satellite data resource to help users to find the remote sensing information effectively. In order to solve the problem of single organizational structure of satellite quality evaluation module and retrieval efficiency, we designed a multidimensional data model of satellite quality evaluation module information based on “star” pattern. The model can be used for quickly displaying dynamic module information of satellite quality evaluation from multiple perspectives and improving the retrieval speed. The model was applied to design the organizational structure of ZGZHLPJ system, and the system organizational structure became more orderly and stereo, by which verified the practicability of the model.
