                         acquisition of TM/Landsat data and water samples were obtained at 
                         two different days during 1991. The analysis of the {"}in situ{"} 
                         data set showed oligotrophic conditions during both campaigns. 
                         Radiometric and geometric correction of the satellite images were 
                         carried out. The digital number average of 3 by 3 windows of bands 
                         TM1, TM2 and TM3 at each sampling area were determined. These 
                         digital numbers and the sampled chlorophyll-a concentrations were 
                         statistically analyzed using the stepwise model. This method 
                         generated a statistically reliable model to estimate the 
                         concentration of chlorophyll-a in the surface of the water. The
