             abstract = "The first China-Brazil Earth Resources Satellite (CBERS-1) was 
                         launched in 1999 and was substituted in 2003 by CBERS-2. CBERS- 1 
                         and CBERS-2 have the same specifications and carry three sensors: 
                         Wide Field Imager (WFI), High Resolution CCD Camera (CCD) and 
                         Infrared Multispectral Scanner (IRMSS). In general, the images may 
                         have a blurred appearance due to the cumulative effects of the 
                         sensor instruments and image motion produced by the satellite 
                         movement. This blurring effect can be described by the Point 
                         Spread Function (PSF) which enables an objective assessment of 
                         spatial resolution through the parameter known as EIFOV (Effective 
                         Instantaneous Field of View). Therefore, this work describes three 
                         approaches to estimate the effective spatial resolution of 
                         CBERS-CCD cameras. The first approach uses artificial target to 
                         estimate the EIFOV in across-track and along-track directions 
                         simultaneously, while the other approaches use natural targets to 
                         estimate the EIFOV in both directions separately.",
