Cartographic data represents the main and basic component of a Spatial Data Infrastructure. SDI, in turn, has the role of supporting, with strategic information, the most diverse political and economic actions, in the management and planning of public actions. Thus, this work aims, initially, to present an overview of cartography in Brazil through the analysis of the evolution of topographic mapping coverage in the country. For each of the main scales used, a coverage map was created. The analyzes reflect three different periods (until 1997, between 1998 and 2007, after 2008) in order to relate how and to what degree, the creation of Brazilian National SDI (in 2008) had an impact on the mapping production in the country. Given the current panorama, as a final objective, this paper aims at to present proposals to leverage the coverage of this reference data. One of them is the use of new data sources such as Volunteered Geographic Information, especially in areas with outdated mapping or without mapping, as has already been used in some countries. Another proposition is to share the responsibility of mapping through partnerships with other levels of government, which would result the decentralization and the optimization of cartographic production.

Imagens de sensoriamento remoto são amplamente utilizadas na extração de informações para a geração de produtos cartográficos, devendo ser avaliadas quanto à sua qualidade posicional. O objetivo do trabalho foi avaliar a qualidade posicional de um lote de ortoimagens RapidEye em uma porção do território brasileiro e verificar a possibilidade de utilização dos dados de propriedades rurais georreferenciadas do SIGEF/INCRA no processo de avaliação. Os resultados indicaram a existência de ortoimagens RapidEye com características planimétricas não correspondentes às especificações do produto, sendo observada a ocorrência de discrepâncias espacialmente concentradas. Foi possível concluir que os dados georreferenciados de propriedades rurais disponibilizados pelo SIGEF são passíveis de utilização na avaliação da qualidade posicional de imagens.

Brazil has a large area with missing or outdated mapping on the largest scales of its authoritative mapping. The use of data from collaborative mapping platforms appears as an alternative that may contribute to minimizing this problem, either by updating or completing the mapping coverage in Brazil, as proposed or performed by some National Mapping Agencies abroad. The present work aims to analyze a methodology to provide accurate and documented integration of volunteered geographic information and the Brazilian authoritative mapping. The proposal starts with the semantic compatibility between the conceptual models adopted in both official cartography and OpenStreetMap platform. The research continues with the identification of object classes with the most significant potential for integration. Finally, we developed some experiments to evaluate and validate the OSM data integration process in a 1:25,000 scale cartographic database. Even in regions with a recent mapping, the results of the preliminary assessment indicate the potential for an increase of about 52% and 16% of features in the ‘road system’ category, which suggests a very promising method for use in areas with missing or outdated mapping, and its applicability to other categories.
