                         Satellite images, being periodically acquired, can help in acreage 
                         estimates at several levels. This work compares the results of 
                         digital classification of images from Landsat and CBERS satellites 
                         for estimating soybean acreage at county level. The study region 
                         is the grain producing zone in the state of Rio Grande do Sul, 
                         Brazil. The accuracy assessment was done through 100 randomly 
                         distributed points in two counties. Results were similar for both 
                         satellite images, with small errors and high agreement between 
                         classification and field measurements. It is concluded that CBERS 
                         images may be used as substitute for Landsat images in soybean 
                         acreage estimates in the studied area.",
