Abstract

Systematic surveys of the vegetative cover in Brazil include the semi-detailed mappings conducted within the scope of the Radam and Radambrasil projects, between 1971 and 1977, based on side-looking airborne radar images, and more recently, the assessments, based on Landsat 7 ETM+ imagery, of the remnant vegetation cover of the Brazilian biomes (MMA/PROBIO), finished in 2006. In a little more than 30 years, many changes have occurred, both in vegetation cover as well as in orbital remote sensing. In this review article, we discuss, from a conceptual and technological perspective, the evolution and the state of the art of imager sensors, as well as some of the enhancement techniques utilized for decoding (e.g., in biophysical parameters, etc.) and classifying the spectral response of vegetation. Likewise, we present the main current (pioneering) initiatives for land cover monitoring of the Brazilian biomes.
