Space Environment Simulation Platform For Multi-source Spatial Database Design And Application

Along with the development of modern times survey technology and spaceflight technology, survey safeguard range will extend from the earth to the outer space. The close-to-earth spatial environment resource information storage and managing technology is the base of space research and spatial environment resource information will become important part of close-to-earth spatial environment base establishment. So it has much meaning to construct the multi-source space database.In order to manage and apply the huge and complex data of the close-to-earth spatial environment resource scientifically, multi-source space database and its service system have been designed and realized in this paper, the corresponding service interfaces of database have been developed and the major function and application are provided for the spatial environment visual platform.The major study contents are listed out as follows.1. The space-time characteristic about spatial environment resource data has been analyzed, as well as the frame design of the spatial environment visual platform and its database service.2. The organization and management pattern for multi-source space data have been discussed. The space data pattern supported by the Oracle database has been analyzed. The index arithmetic of multi-source and multi-resolution images database and the design of multi-source space database based on HLA have been discussed and analyzed in details.3. The design of the service interfaces in the multi-source space database is another important research emphasis in this paper. Based on the interview approach of Oracle OCI, a interface COM...
