The Superposition Display of Massive Remote Sensing Images with Different Projections

With the development of sensor technology, remote sensing technology has entered a new stage, which can provide various remote sensing data quickly and timely. In some basic process of remote sensing image, such as change monitoring, fusion, and correction, superposition display becomes a direct and rapid method, which can evaluate the quality of the work. In order to solve the problem of the slowness during the superposition display of remote sensing images with different projection, this paper presents some solutions, such as read-write technique of remote sensing images, image block technique, cache technique, dynamic re-projection technique; and these techniques are used in our remote sensing images processing platform. Practice shows that these techniques in this paper can better settle the problem of the slowness during the superposition display of remote sensing images with different projections.
