| Abstract: | The main features of the MODIS sensor carried by the EOS satellites and the principle of monitoring forest fire using MODIS data were introduced. The threshold value which needed to be estimated and identified automatically in using MODIS data to monitor forest fire was analyzed and researched and got a rapid and simple way to set ch21 and ch21-ch31 thresholds. And the method was proved to be feasible and effective to monitor forest fires by examples. |
