Abstract
The use of images by orbital remote sensing has shown great utility in environmental geology and engineering by mapping surveys and researches. The advantage of employing such remote sensing technique is due not only to its wider coverage area but also to its high spatial resolution quality, allowing a range of possibilities by means of operations among electromagnetic bands. The main purpose of this paper is to do comparisons among Landsat images of TM and ETM+ sensors, in Rio de Janeiro Region, Brazil, by means of color compositions that come from IHS-RGB Transformation and compositions that come from Ratios Band as well. Our studies point that ETM+images presented better results in landslides studies due to their better accuracy in comparison to TM images.
