Precision Analysis of Forest Fire Burnt Areas by Using ETM+ Image

摘要

Space-borne multi-sensor data could provide fire scar and burn severity mapping. This paperwill present detail mapping of burnt areas in Cheongyang·Yesan of Korea with ETM+ image.Burn severity map based on ETM+ image was found to be affected by strong topographicillumination effects in mountainous forest area. Topographic effect is a factor which causeserrors in classification of high spatial resolution image like IKONOS image.Minnaert constants k in each band of ETM+ image is derived for reduction of mountainousterrain effects. Finally, this paper computes quantitative analysis of forest fire damage by eachforest types.
