                         recent technical evolution and the free of charge access to 
                         several geo technologies, it has been observed that the use of 
                         these tools are relevant to the planning of agricultural 
                         activities in order to maximize the use of natural resources in a 
                         more sustainable manner. In this context, the physiographic 
                         conditions of a certain region may or may not allow agricultural 
                         exploration bringing direct consequences to crop yield and to the 
                         environment. O pilot area was selected in Minas Gerais State 
                         comprising the municipalities of Aguanil, Boa Esperan{\c{c}}a, 
                         Campo Belo and Cristais. In order to achieve the proposed 
                         objectives a pre-processing with the SRTM regular grid was carried 
                         out, to correct for negative values. Following, an altimetry mash 
                         was associated to a cartographic projection system (UTM/SAD69) and 
                         organized in a geographic information system of public domain 
                         (SPRING). From the pre-processing and the application of 
                         derivative methods, the slope and slope orientation variables were 
                         obtained in spatial numerical format (regular mash) and thematic 
                         map. The results showed that it was possible to obtaining the 
                         coffee crop profile for each municipality with regard to these 
                         variables.",
