Space image simulation needs a complete description and effective management of the information acquired from the unmanned airship low-altitude remote sensing measurement system. So a database system is built, which integrates hyperspectral image, high resolution image, infrared image, spectrum data, atmosphere data, environment data and GPS information. According to the data characteristics of the measurement system, a mobile storage model is proposed. By utilizing the superiority of binary large object (BLOB) supported by Oracle and the data partitioning technology, the model can realize the integrated management and mobile storage of the multi-source image information. The database system is developed by using Visual C++ as foreground development tool, Oracle objects for OLE (OO4O) as accessing interface and Oracle as the background database management system. Base on the adopted techniques, this system not only realizes complete description and effective organization of the data of the measurement system, but also provides a systematized and specialized information platform for space image simulation and quantitative application of multi-source remote sensing data.
