Utilização de imagens do satélite Landsat 8 para a análise da emissividade e da temperatura de superfície da aglomeração urbana de Rennes (França).

Résumé

This paper aims to analyze the emissivity and surface temperature for the agglomeration of Rennes, France. For this, two formulas of emissivity (estimated from the Normalized Difference Vegetation Index, NDVI data) were used and their results were compared. The estimation of surface temperature was conducted from the emissivity data obtained in the previous stage. The form of the surface heat island (SHI) varied according to the emissivity used and the season. We conclude that the two formulations can be used for calculating the surface temperature and that the vegetation and its water content was shown to be an important variable in the analysis emissivity and surface temperature in the temperate zone.
