Abstract

This study aimed to conduct a multi-temporal analysis of the electromagnetic spectrum, in Garanhuns-PE from the albedo. Using the geo of Remote Sensing and Geographic Information Systems (GIS), plus the rasters of the National Institute for Space Research (INPE), it was possible to estimate and map the changes in reflectance patterns of the targets. While urban polygon has expanded the ability of reflectance, targets also increased. Showing that not always the maximization of albedo means thermal reduction. Soon some objects can have a great capacity for reflection, but absorbed energy is conserved longer.
