Estimation of Forest Fire Burned Area Based on Landsat 8 Remote Sensing Data——A Case Study of"3·18"Forest Fire in Hezhang County,Bjjie City,Guizhou Province
Taking the forest fire in Hezhang County,Bijie City,Guizhou Province on March 18,2021 as an example,this paper used Landsat 8 remote sensing data,and remote sensing data processing and anal-ysis software(ENVI),to extract and calculate the burned area based on image preprocessing,calculation of normalized vegetation index and burned area index.The results showed that the burned area of forest fire could be extracted well by using Landsat 8 data,and the accuracy of burned area was 96.2%.
