A reflection is offered on the complementary relations among documentary languages, terminology, and ontologies, in regard to the study of conceptual relations used to organize knowledge. Building on selected texts from the international literature, the relations between documentary languages and different emerging technology solutions are analyzed, taking SKOS as a model; and also the relations among thesauri, ontologies and terminology, with the support of the theoretical concept of documentary representation. The adoption of the principles of terminology, as understood in Information Science, in building ontologies is supported; and the innovative opportunities offered by ontologies to the improvement and processing of conceptual relations in indexing languages is defended.

Esta coleccion de mapas y planos de ciudades de America Latina, se elaboro como resultado de la investigacion realizada sobre crecimiento urbano en la region. El conjunto de mapas presenta la ubicacion, en el territorio de cada pais, de todas las ciudades que en 1970, tenian 50 mil habitantes o mas. Las ciudades se presentan por categorias de tamanos, destacando en los mapas las vias de comunicacion, ademas de los principales rasgos del relieve y de la hidrografia. Cada mapa esta acompanado por otro similar que presenta la situacion que tendra en 1980 el conjunto de ciudades de cada pais estudiado, elaborados en base a las proyecciones realizadas durante el estudio. Los planos de ciudades muestran el crecimiento fisico historico de 10 ciudades importantes de los 7 paises estudiados (Argentina, Brasil, Colombia, Chile, Mexico, Peru y Venezuela), desde alrededor de 1940 hasta en torno de 1970.

Among the crops commercially exploited in Brazil, the coffee has a great economic importance, especially in the states of Minas Gerais and Espirito Santo. In the search for higher yield and lower environmental impact, farmers and researchers seek to develop new technologies that result in greater efficiency in various production processes of the coffee. For this, the adoption of precision agriculture in the management of operations in coffee crops, called precision coffee, has shown results that justify its use, by identifying the spatial variability of several variables, allowing its localized management and in the proper intensity. Unlike conventional management that is based on the average of observations in an area, precision agriculture uses a more detailed sampling, based on a sampling grid, which allows to represent in greater detail the reality of farming. Many previous studies have identified the spatial variability of the production of coffee system variables, but without worrying about the quality of information obtained due to the sampling grid used as precision and accuracy. Given the above, the objective of this study was to evaluate the quality of four different sampling grids for different variables and three times, in order to identify the most appropriate grid for use in precision coffee. Also aimed to compare the results between the precision coffee and conventional, according to reference values.
