Since the beginning of its operation in 1969, the Companhia de Pesquisa de Recursos Minerais (CPRM) began, gradually, to monopolize the work of geological mapping in the country. Relevant activity from 70s and 80s includes the Geological Map of Brazil (1:1.000.000), published between 1974 and 1979, and the integration of information with the implementation of the Geological Map of Brazil and adjacent ocean areas, including mineral deposits, at the scale 1:2,500,000 (1981). The resumption of basic geological surveys from 1986 took place with the implementation of the Program Basic Geological Surveys of Brazil. In the 90s geological maps have been produced normally in digital media, although the databases are stored in the structure of mainframe, in use since the 70s. In 2000, the Company initiated a vigorous program of modernization in the area of information technology, to present their products through the mapping technology of Geographical Information Systems and relational databases. Today, using the most modern features, the Geological Survey of Brazil has the mission of "Produce and divulge the basic geological and hydrological knowledge required for sustainable development in Brazil", so that everyone can have|access to these products through online services
