Implementação de rotinas computacionais livres na geração de anáglifos e sua aplicação nas fases de pré-campo dos estágios de campos da Faculdade de Geologia de Marabá

Abstract

Most fieldworks of Unifesspa's geology faculty always takes place near the headquarters of the municipality of Marabá, in important areas within Carajás Mineral Province, in the Araguaia Fold Belt and / or along the Parnaíba Basin. For the preparation of the pre-field map, students are instructed to photo-interpret remote sensing products, when used with proper spatial resolution, the work scale allows the manual extraction of the various natural or anthropic elements that can be mapped. Therefore, three-dimensional visualization makes the process of extracting geological information more suitable. With the advancement of micro-computing in the last decades, it is possible to analyze, in fast and secure methods, orbital images of the most diverse sensor systems. The present work aims at the creation of anaglyphic images of the field areas, using free softwares, so that the realization of the photointerpretation is done directly on the computer screen, in this way this methodology allows the simultaneous identification of geological features and their vectorization, in a GIS environment.
