| Abstract | Este trabalho analisa o potencial de imagens com alta resolução espacial (satélite QuickBird) para mapear o relevo de um setor do Planalto das Araucárias, no nordeste do Rio Grande do Sul, Brasil. A área teste foi o Centro de Pesquisas e Conservação da Natureza PRÓ-MATA. Em 1994, o PRÓ-MATA foi criado para desenvolver estudos e ações visando à conservação da Mata Atlântica. Imagens QuickBird e técnicas de geoprocessamento foram usadas para executar o mapeamento. Foram realizados trabalhos de campo para conhecimento da área e levantamento de pontos de controle, utilizando GPS diferencial. As etapas do trabalho foram: gerar um Modelo Digital de Elevação (MDE), realizar fusão e corrigir a geometria das imagens QuickBird, mapear a hidrografia e a geomorfologia. A partir do MDE derivaram mapas de declividades, altimetria e visualizações em 3D da área de estudo. O mapa geomorfológico foi criado na escala de 1/15000, sendo considerados aspectos morfológicos e morfométricos do relevo. A rede de drenagem foi mapeada com detalhe. Na área de estudo, o relevo acidentado com altas declividades dificultaram a aquisição dos pontos de controle e a correção geométrica das imagens. Não obstante, a alta resolução espacial das imagens QuickBird permitiu mapear a área com detalhes, auxiliando na otimização dos trabalhos de campo. Os resultados demonstraram que as imagens com alta resolução são adequadas para analisar e mapear o relevo em áreas acidentadas. Abstract This paper analyzes the potential of high-resolution images (QuickBird satellite) to mapping the relief features of a sector of the Planalto das Araucárias, an elevated area in northeastern Rio Grande do Sul, State, Brazil. The Center for Research and Nature Conservation PRÓ-MATA was chooses as an experimental area. In 1994, the PRÓ-MATA was created to perform studies and to propose actions for the conservation of the so-called Mata Atlântica. QuickBird data and GIS techniques were used to execute the mapping. Two field surveys were done to obtain ground-based information and to get control points through differential GPS. Main steps of the work: creation of a Digital Elevation Model (DEM), merging and geometric correction of the QuickBird image, mapping hydrology and geomorphology. Topographic features, such as slope, elevation and 3D views of the area were extracted from the DEM. Considering the morphologic and morphometric features of relief, the geomorphologic map was constructed at the 1/15,000 scale. The drainage network was mapped in detail. At the area under study, the strong relief and the steep slopes made it difficult to get ground control points and to correct geometric distortions of the image used. Nevertheless, the high spatial resolution of the image allowed a detailed mapping of the area, optimizing field surveys. The results show that the QuickBird image is fully adequate for study the relief of high-elevation area with rough terrain. |
