- Abstract
The preparation of thematic maps related to the mining activities is imperative for the development of procedures that maximize mineral exploration and production of this activity. The politic of exploitation of quartzite explored in Ouro Branco in the state of Rio Grande do Norte is limited to the extractive model without adding value to this mineral commodity. Another obstacle was the scarce of thematic maps of the municipal district. This limitation was minimized with the development of this study. The objectives of this study were to generate thematic maps and the preparation of a geo-referenced database as a way to store, to query, to visualize, to manipulate and to generate information for the proper establishment of mining activities in the study area. The materials used were the Topographic Map of Jardim do Seridó and orbital images ETM/Landsat-7. The mapping procedures of thematic maps were performed in Georeferenced Processing Information System (SPRING), supporting fieldwork. The results showed that it is possible to generate, organize and store in a single database, thematic maps related to mining, contributing to the formation of a technician-managerial tools for the appropriate development of mining of quartzite and to support the aggregation process value of the final product. In this sense, the collection of the generated database is a support for the economic growth of the municipality.
