[0072] The experimental data adopts medium-resolution Landsat-8 satellite remote sensing Level 1 (L1) product data, and the map projection is UTM-WGS84 Antarctica polar projection, which comes from the official website of the United States Geological Survey (USGS). The research target is the Grampians National Park Fire (GNPF) in Victoria, southeastern Australia. This experiment uses January 12, 2014 (before the disaster) and January 28, 2014 (after the disaster). Image data.
[0073] Experimental results:
[0074] 1. Analysis of the ability of different methods to separate burnt areas and non-burned areas
[0075] Based on 0.1% random samples, respectively calculate the separation degree of 5 kinds of methods (CVA, dNBR, dMNBR, dBT and the present invention) in the research area to extract the gray scale map of the burnt area. The higher the value, the stronger the ability to separate burned and non-burned areas. see results figure 1 . Depend on figure 1 It can be seen ...
