In the embedded satellite map system with limited resources, the linear quadtree is used to encode the satellite map hierarchically and blocked, optimize the map data access mode, reduce the loading redundancy of memory data, and realize the rapid display of map. Through WindML dual cache technology, map redraw jitter is eliminated under VxWorks real-time operating system to smooth image output. The results of the program operation show that the method has obvious effect on improving the response speed of the terminal and optimizing the image output.
