Abstract

This research is the application of remote sensing and geo-informatics in the analysis of forest fire damaged areas in the forest reserve area and conservative area in Mae Hong Son Province . The NOAA satellites were used to analyze the hotspot on the surface of the earth. Forest fire damaged areas were analyzed using data from Sentinel-1 satellites due to changes in reflectance. Using the sample area to distinguish from the damaged area data from real forest fires by the supervised classification methodology. The study found that during the period from January 1 to May 31, 2016, Hotspot occurred in the study area of 1,207 point. The month with the most hotspot was March with 712 points. The area with the most Hotspot point is the forest reserve area of Salween of 192 points. Analysis of forest fire damaged areas by supervised classification. There are areas damaged by forest fires in study area size 10,528.69 rais divided into forest reserve area size 5,887.34 rais and conservative area size 4,641.35 rais. The areas most damaged by forest fires are forest reserve area of Salween of damaged area are 1,832.26 rais. The accuracy of classification of forest fire damaged areas in the forest reserve area and conservative area was found that the results of the classification of damaged areas were 89.04%.
