Images Fusing in Remote Sensing Mapping

摘要

The remote sensing images fusing is a method, which integrates multiform image data sets into a new data set by geometry matching, color transformation and other ways. During mapping the LiJiang county in YunNan province with high-resolution remote sensing image, we found that it is a good way to utilize the technique of image fusing, which includes image matching, image interpolation, edge enhancement, and imagery updating, to improve the mapping quality. After iterative experiments, we explored a new way to update and fuse based on TM image, SPOT panchromatic image and the air photos. In the fused image, various RS images information can supplement each other, so the fused image not only have abundant spectrum information, but also reserve high spatial resolution. It proves that imagery fusion is an important way to improve represent ability on map of imagery.
