Embodiment Construction
[0046] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0047] In the existing technology, the commonly used remote sensing image data scheduling method is to first preprocess the remote sensing image into multi-level tile data, see figure 1 As shown, the tile data segmentation method is usually in the longitude-latitude coordinate system, the Middle East Hemisphere region and the Western Hemisphere region of the global remote sensing image are each used as a top-level grid, and then the top-level grid is divided into quadtrees step by step, In this way, the remote sensing image is divided into multi-level tile data, and tile data of the appropriate level within the current browsing range are transmitted when requesting to browse a certain a...
