IFEMS: a new approach for monitoring wildfire evolution with NOAA-AVHRR imagery
A new approach for monitoring wildfire evolution was developed. It was achieved by integrating both the burned area mapping system and the fire detection system. Multi-spectral multi-temporal images of the National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA-AVHRR) were employed. The new system has an excellent performance in monitoring fire growth due to its ability of capturing areas that were burned completely between two consecutive images, as well as those which were burned before the monitoring time. In addition, the system has the ability to differentiate among burned areas, active fire (fire front) and the area beneath flames. The algorithm of the system is described. The false alarm due to the saturation problem of channel 3 was avoided. The integration of the system with fire simulation programs for fire monitoring is discussed.
