This paper provided a new based on the mobile oriented spatial information positioning algorithm. The algorithm used quadtree theory has nothing to do with a specific space to operate object excluded, so that the spatial position of the operation be able to fast access to the operation object, improve the spatial position operational efficiency. The application experiment were given out to prove this design model’s feasibility, Analysis of experimental results, and the contrast between the existing Web position algorithm and based the Quadtree theory position algorithm also validated that the latter was more efficient and faster for spatial search. This algorithm can be applied to satellite remote sensing image positioning for fast search and location.
