                         Sensing data and GIS processing is presented. The sources of 
                         information are the images collected by TERRA Polar Platform 
                         through the MODIS Sensor and the ortho-rectified GEOCOVER mosaics 
                         generated from the ETM+ Sensor onboard the LANDSAT-7 Satellite. 
                         The software to undertake the interpretation and the measurements 
                         is SPRING. TERRA and GEOCOVER products are available at no costs 
                         by NASA and SPRING can be downloaded from INPE at no costs as 
                         well. The procedures of photo-interpretation are based on a 
                         special routine available in SPRING known as Raster Edition. The 
                         routine allows the analyst to edit the interpretation directly in 
                         the display of the monitor. Within these parameters the method can 
                         be applied to any river of the planet as long as images 
                         free-of-clouds are available. Amazon and the Nile were selected 
                         because they are the longest river yet mapped through traditional 
                         methods. The results indicate that measurements obtained through 
                         MODIS and GEOCOVER match quite well as they lay within a linear 
                         error smaller than a MODIS pixel (250 meters) for a distance 
                         greater then 6900 kilometers. Results also show that the Amazon 
                         measures 6,992.15 kilometers and the Nile extends for 6,852.06 
                         following their longest channels. The method indicates that the 
                         Amazon River is 140.09 kilometers longer than the Nile.",
