Rapid Display Technique of Massive Remote Sensing Image
海量遥感图象快速显示技术

Massive data of remote sensing images has been generated as remote sensing technology develops rapidly. The disfluency when displaying massive data was once a problem. We found that these phenomena mainly occurred at the operation of panning or zooming out. In this paper, we analyze the reason of these phenomena at current level of computer software and hardware technology. We also present one method to solve this problem based on the intermediate-image technique, raster-division technique, cache technique and intermediate-image-sequence technique. We had programmed on Windows 9X/2000 platforms by Visual C 6 0 and applied this system at the investigation project of natural environment by remote sensing method in Zhejiang Province. In this project we accomplished the selection of reference points, image inlay and the matching of the TM images of Zhejiang province at 1997 and 2000. Our practices showed this method can avoid the stagnation when displaying in existing device conditions.
