Geoprocessing in health area.

The map's usage and the concerns about geographic distribution related with diseases are not a recent issue. A classical example is the John Snow survey -maps were used to locate cholera's cases and related them with the water supplying. The spatial representation techniques are fewer used in health sectors due to troubles in managing such information. So, the aim of this survey was to establish the disease spatial distribution in Ribeirão Preto, 2002. Secondary data were used to elaborate this study. The spatial distribution of cases was realized by using the MapInfo 7.8 software. Although many cases were concentrated in the northeast region in the city, which consists the quarters of low economical income. The results contribute to show the Tb spatial distribution in Ribeirao Preto, they also reinforce the space category as a methodological alternative to manage, to monitor and to evaluate the health actions by directing interventions to decrease the iniquities.
