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 paper will 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 topographic illumination effects in mountainous forest area. Topographic effect is a factor which causes errors in classification of high spatial resolution image like IKONOS image. Minnaert constants k in each band of ETM+ image is derived for reduction of mountainous terrain effects. Finally, this paper computes quantitative analysis of forest fire damage by each forest types.
