[Abstract]:Since its launch in April 26th 2013, the Gaofone satellite has acquired a large amount of data, which has reached the TB level and is still growing. Based on the demand for effective management, retrieval and display of high score data, The storage model of mass data and the factors affecting the speed of image browsing are analyzed. The experimental results show that the image pyramid is constructed by JPEG compression and bilinear interpolation with compression quality of 50%, and the size of 64 脳 64 slices is used for data storage. Through the construction of GDB Raster Catalog layer, it can store and quickly browse and display the massive remote sensing data, and meet the demand of data management and display in the application of high score series satellites in the industry.
