The dimensioning of an air monitoring and control network requires the knowledge of the area where atmospheric pollutants, released by stationary and mobile sources, tend to concentrate, as well as understanding their dispersion phenomena. The areas of atmospheric pollution monitoring in the metropolitan region of Rio de Janeiro are being discussed since the early eighties when the air basins limits were estabilished based in topographic maps. This project consists on applied research to the establishment of spacial configuration and mapping the air basins in the metropolitan region of Rio de Janeiro with digital data. This effort is justified considering its benefits for the society in general, the increased knowledge of air quality conditions and its behavior over time. The study is concentrated in the metropolitan region of Rio de Janeiro based in the necessary data for the evaluation of the air masses dinamic in the study area and their characteristics to define the new air basins with support of geographic information systems. Based in cartographic digital data a GIS was projected to comply with digital mapping requirements of the air basins, air quality monitoring stations, the pollutants sources and the main traffic routes. Regions with same characteristics were identified and mapped for various scenarios using GIS. A georeferenced database, previously modeled, was created to allow spatial queries of environmental management needs. Using the GIS, inefficient monitoring areas and critical atmospheric pollution areas were identified and new air basins created from digital data were proposed. The GIS showed to be an interesting and efficient tool for environmental management of air quality in the metropolitan region of Rio de Janeiro, with GIS use it was possible to represent all the necessary elements to evaluate the spatial configuration of the air basins and it was possible to visualize the monitoring stations spatial distribution in the air basins proposed.
