Abstract

This research aims to identify burned areas within the municipality of Mayarí in the Mensura-Piloto National Park from Sentinel 2 satellite images, obtained free of charge through the Browser Copernicus Data Space portal. Annually during the dry season this municipality is affected by fire, caused mainly by anthropogenic and tropical action. Sometimes this phenomenon gets out of control, causing large fires that seriously affect the ecosystem of the region. The NBR spectral index is used to highlight the areas affected by fires and to classify the severity of the event, showing as a result a classification according to a range of key values in qualitative continuous order offered by the Key & Benson severity thresholds (100 / 270 / 440 / 660 / Max). The ranger sites reported a total of 3 612 ha of Burned Area, classified between burn zones with high, moderate and low severity, which corresponds to 2,77% of the total area of the municipality, a worrying figure, which should alert the municipal government officials in charge of Disaster Risk Management, to assess damages and analyze the respective recovery processes of vegetation cover and the ecosystem in an effective manner.
