Calculation of damage in forests using Sentinel-2

Data from Senitnel-2 after atmospheric correction were used to determine forest damage caused by the storm. On the territory of Poland the destruction took place on 11-12 August 2017. In order to determine the area of destruction images before and after the storm were taken. Then the supervised classification was implemented for data from both dates. The area of damage was calculated on the basis of the classification result, the area of forests classified on the image before the storm and afterwards allowed to determine the area of losses.
