Análise comparativa de metodologias aplicadas nas estimativas de áreas produtoras de café no estado de São Paulo no ano-safra 2015-16.

Abstract

The outcomes derived from two methodologies used in the state of São Paulo in the crop year 2015-16 in coffee areas were evaluated in order to help improve the accuracy of the results about crop areas. In the first technique, the areas were estimated by orbital remote sensing. In the second model, the estimates were obtained by the subjective method. The estimates arising from these two methodologies are evaluated in this study by region and state. The high correlation found between both indicates that they can be combined, thus creating a new methodology that emphasizes the virtues of each method and minimizes their limitations.
