The Trend of Development of Multi-Source Remote Sensing Data Fusion

With the fast development of remote sensor technologies,the development of new methods and algorithms of multi-source remote sensing data fusion techniques are emerging one after another.Usually fusion techniques can be classified into three levels: the pixel level,the feature level and the decision level.The paper has discussed the following development trends for image and data fusion.The first is new image fusion method for high resolution images;the second is user-oriented image fusion assessment,the third is LiDAR,Optical and SAR data fusion for ecological modeling,and the final is distributed sensor network data fusion.
