Abstract

Este trabalho tem como propósito identificar o comportamento espectral de alvos urbanos (asfalto, concreto, basalto, granito e estrada sem pavimentação), utilizando um espectrorradiômetro e estabelecer sua relação com as bandas espectrais do sensor ASTER. Os sensores de média resolução espacial, como o ASTER, não permitem a diferenciação adequada de alvos urbanos, sendo que, o estudo do comportamento espectral destes alvos pode ajudar a minimizar esta limitação. O estudo foi realizado no campus da Universidade Federal de Santa Maria e na Base Aérea de Santa Maria. Palavras-chave: Espectroradiômetro. Sensoriamento remoto. Alvos urbanos. Reflectância. ASTER. Evaluation of the spectral behavior of urban targets with the use of the spectroradiometer and its relation with the spectral bands of ASTER sensor The purpose of this work is to identify the spectral behavior of the urban targets (asphalt, concrete, basalt, granite and road without pavement), using a spectroradiometer and to establish its relation to the spectral bands of the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) sensor. The sensors of medium space resolution as the ASTER, do not allow the adequate differentiation of urban targets, however, the study of the spectral behavior of these targets may help to minimize this limitation. The study has been realized at the Federal University of Santa Maria and Air Base of Santa Maria. Key-words: Spectroradiometer. Remote sensing. Urban targets. Reflectance. ASTER.
