Various approaches were used to combine crop growth models and GIS. In this paper we describe the general features of the system that have been developed and discuss the conceptual strengths and weaknesses of each. aAgroinformatics aComputadores aplicados a agricultura aComputer in agriculture aInformatica na agropecuaria aInformation technology in agriculture aTecnologia de informacao na agricultura1 aJONES, J.
