In order to create a rapid, easy, and circulatory capabilities for multipurpose applications of remote sensing image, a network-oriented satellite remote sensing circulation architecture was proposed, and its key components was discussed in the same time. The client scheming and block data disposure were supplements to the integrity circulation architecture, conforming to which, clients can distribute the obtained remote sensing images and transfer to be servers; remote sensing image circulation utilization was realized.

Abstract:In visual navigation system, a method of construction and scheduling of multi-resolution LOD terrain is designed according to the influence of terrain precision on super low flight. First, the tiled pyramid is constituted to manage the terrain data, which is organized by quadtree. The terrain complexity-based node selection criterion is used to select the required blocks for rendering. Then, the structural similarity of quadtree nodes is made use of to symmetrically cluster two-level nodes, which is suitable for batch scheduling of terrain data. Experimental results show that this method improves the terrain precise from a certain range of the aircraft, reduces the frequency of data scheduling, and enhances the rendering frame rates of navigation scene.
