Uso de imagens de satélite e do sistema Openstreetmap no ensino universitário para produção e atualização de mapas digitais livres e abertos na Internet.

Abstract

This study analyzed Internet free and open map systems and elected OpenStreetMap as appropriate for undergraduate students who have studied and tested it. To confirm the applicability, we performed a test of data update of OpenStreetMap system. The test consisted in the introduction of some data generated by GPS; digitization of satellite image made available on the system itself by Bing and insertion of other spatial information, known by the authors of the work, on some internal roads of the studied area and its surroundings in the OpenStreetMap, and the verification of the existence of such data in other systems, as Google Earth and Wikimapia by viewing the maps available. We also analyzed the level of difficulty of using these systems for undergraduates. OpenStreetMap proved easy to be used by students. The adoption of tasks such as mapping towns by disciplines of Geography, Cartography, Environmental Management or related disciplines contribute to student learning and could leverage the production and updating of Internet free and open map. There is the need for disclosure and learning among young people from local communities, from small towns, inclusion in the curricula of undergraduated courses as to graduates who in the future will be using and enjoying this tool.
