Abstract

The objective of this study is to evaluate the relation between the severity of burnings and the heat sources in the city of São Pedro do Piauí, state of Piauí, based on the spectral index NDBR (Normalized Burn Ratio) considering the temporal clipping 2006 to 2016. The methodological procedures include bibliographical revision and acquisition of the cartographic base of the spatial and temporal clipping of the research. The records of the heat sources obtained in the Burning Database (BDQueimadas - INPE) and satellite images from the USGS (United States Geological Survey), from 2006 and 2016, were used to calculate the NBR spectral index (Normalized Burn Index). It was observed a total of 4,857 hot spots in the area under analysis, with a predominance of records in the second half of the year, particularly between the months of July and December, with the peak being the month of October. When considering the spectral index NDBR, using as reference the month of August of 2006 and 2016, the municipality of São Pedro do Piauí did not have sectors classified with: high moderate severity, high severity and nor anomalies, being that much of the municipality was classified with high regeneration.
