Forest fire is the regular event year after year. There are different causes of forest fire
(Intentional and Un intentional) Fire can be classified in to ground fire, surface fire, crown fire.
Forest fire can have a large impact on both economy and ecosystem. Hence, it needs monitoring
for restoring the fire damaged forest region. Traditionally forest fire has been detected using fire
lookout towers at high points in a forested area. Un reability of human observation in addition to
difficult life condition for fire lookout personnel have led to the development of auto video
surveillance system . More advanced forest fire detection system are based on which satellite imagery ?
