Sumario:Argentina. It contains a considerable amount of outstanding information and it is already being used by some municipalities and other government offices. A parallel EIS working station was installed in the Facultad de Ciencias Agrarias Universidad Nacional de Cuyo (School of Agriculture, National University of Cuyo) in order to develop a GIS specialized agricultural information center. Within that reference frame, the results of two studies (4, 13) of the Tunuyán river soils (middle and lower sections) have been incorporated to the EIS. As the first objective, four coverages have been generated within ArcInfo format. Two of them are maps of suitability of soils for irrigation made according to the US Bureau of Reclamation regulations, divided in polygons. The data base supply information about perimeter, area in m2 , id number and capability class for each polygon. The others two coverages have information showing the places where the samples of soils were obtained. The data base supplies information about id number given in the original work and class and subclass for irrigation. The second objective was to analyze the collected information in order to obtain soil maps at a "departamento"(county) level. As a result, coverages with soil type and the areas where they were taken in the counties of San Martín, Junín , Rivadavia, Santa Rosa and La Paz were obtained. The third objective was to find a method of processing the information from the samples points using the Idrisi software in order to establish a new technique of analysis and representation. In this particular case, a map representing the soil aptitudes from Rivadavia County was generated.
