Teledetection technique offers great possibilities for the achievement of advance in the knowledge of nature although not everything expected has been accomplished yet, as there are still important improvements to perform in space, spectral and temporary resolution of data. In addition, a greater scientific rigor in the interpretation of obtained results is necessary, trying not to draw definitive conclusions from environmental studies performed with teledetec- Technology at the service of environment tion. Models elaborated to process data obtained from teledetection should eliminated effects caused by variability in collection conditions, distortion caused by the atmosphere and the influence of parameters such as sun position, slope, exposition and altitude.
