                         launched in 1999 and in 2003 was substituted by CBERS-2. CBERS-1 
                         and CBERS-2 have the same specifications and carry three sensors: 
                         WFI, CCD and IR-MSS. The performance of these sensors can be 
                         evaluated through PSF measurement that enables an objective 
                         assessment of the spatial resolution. This paper describes an 
                         approach to estimate the spatial resolution of the CBERS-1 CCD 
                         camera using two images: an image captured by CBERS-1 satellite 
                         and an image of the same scene of higher resolution captured by 
                         SPOT-4 satellite The method is iterative and the goal is to find 
                         the low-pass band filter parameter that minimizes the Root Mean 
                         Square (RMS) difference between the CBERS-1 image and the filtered 
                         SPOT-4 one. This technique is applied to spatial resolution

                         Pontchartrain Causeway in Louisiana (United States), and, in 
                         along-track direction using an image of Rio-Niteroi Bridge in Rio
