During the year of 2012 was observed one of the most intense droughts of the last years in the Northeast of Brazil. This fact has encouraged some analytic studies using orbital sensors as example the current research. The goals of this research was to calculate and analyze the Vegetation Condition Index (VCI) to the Countryside of Alagoas in view of an analysis of the drought that happened in 2012 in comparison with the last 11 years utilizing orbital images of Normalized Difference Indices Vegetation (NDVI). The dates were obtained with EMBRAPA Informática Agropecuária. The results were exposed in thematic maps and spreadsheet that highlighted areas with the smallest and largest vegetation condition index and the period of occurrence as well.Downloads
