             abstract = "In the city of Bueno Brand{\~a}o, South of Minas Gerais State, 
                         Brazil, the Watershed of Rio das Antas is located prior to the 
                         public water supply and is susceptible to hydro-degradation due to 
                         the intensive agricultural activities developed in the area. The 
                         potato plantation is the most significant cropping in the city. 
                         Because of the possibility of interfering in the preservation 
                         areas, mainly the ones surrounding water courses and springs, it 
                         is very important to do the assessment of the plantation sites, in 
                         order to avoid the risk of water contamination. The procedures 
                         adopted by the agro activity farmers generally present the 
                         following features: intensive use of agro-chemicals, cropping in 
                         places with slopes which are higher than 20%, close to or in 
                         permanent preservation areas. The scope of this study was to 
                         develop the proper methodology for the assessment of the 
                         plantation areas, regarding the short time of procedure, as the 
                         period between the plantation and the harvest occurs in six months 
                         the furthest. These areas vary year in year out, as the plantation 
                         sites often change due to the land degradation. Because of that, 
                         geotechnologies are recommended to detect the plantation areas by 
                         the use of satellite images and accurate data processing. 
                         Considering the availability of LANDSAT medium resolution images, 
                         methods for their appropriate classification were approached to 
                         provide effective target detection.",
