Integration of LANDSAT/ETM+ and CBERS-2/CCD images for change detection in the Amazon region under domain of transition forests

Abstract

Techniques for change detection were improved and applied to information extraction related to landscape monitoring. With the recent availability of CBERS-2/CCD data, the main objective of this research is to show the technique on “Radiometric rotation controlled by a no-change axis (RCEN)”, using a multi-temporal comparison with the LANDSAT-7/ETM+ image. The result of this technique is a change detection-image derived from both sensors, whose map shows the conditions of regrowth/degradation cover and it’s intensity levels.
