                         melhorar o ajuste entre os dois conjuntos de dados. Empregaram-se 
                         an{\'a}lises de regress{\~a}o linear e n{\~a}o-linear,

                         this paper we try to establish the grade of relationship existing 
                         among various Guanabara Bay water quality parameters and LANDSAT 
                         MSS video data. We have chosen an empirical: basis approach, but 
                         we had to select, from the available data, some parameters as 
                         follows: chlorophyll, water transparency using Secchi disk, 
                         salinity and dissolved ammonia. Only two overflights could be 
                         used, due to the fact that in the other ones there were no 
                         simultaneous ground truth data. At the same time, digital video 
                         data processings were compared in order to improve a better 
                         adjustment: between both data sets. Linear and nonlinear 
                         regression analyses were utilized, sets comparing original data 
                         with processed ones by using the correlation coefficient and the 
                         estimation mean error. The results showed that it is possible to 
                         obtain better adjusted data by means of some radiometric 
                         correction programs with a phsycal basis, contrast ratio, and 
                         normalization.Some other interesting results have been found, such 
                         as the detection of certain targets in water. comparing original
