GF-4 Satellite Fire Detection with a improved Contextual algorithm
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The GF-4 satellite has a moderate spatial resolution and is capable of high temporal frequency observation. Thus, it can play an important role in the acquisition of information regarding fires. In this study, the characteristics of brightness temperature difference between fire point area and non-fire point area are comprehensively analyzed. Employing the advantages of high-frequency continuous observation of these data, an improved algorithm for joint spatial attribute detection usingdoi:10.1109/jstars.2021.3132360 fatcat:butordzwhrax5ng4zudxwx3vtm
