| Abstract | Este trabalho apresenta um estudo comparativo, no qual se avalia a eficácia e a eficiência de três ferramentas computacionais para a delimitação de bacias hidrográficas e a extração da rede de drenagem, a partir de dados altimétricos oriundos de diferentes fontes: imagens SRTM originais da USGS (90 metros), imagens SRTM interpoladas (30 metros) do projeto TOPODATA e imagens ASTER (30 metros). As ferramentas computacionais utilizadas foram o módulo ArcHydro da solução comercial ArcGIS, o software livre TerraHidro e o módulo livre HAND executável em IDL. Foram avaliadas as dificuldades e facilidades no uso dos dados, o tempo de processamento e os produtos obtidos para o caso da bacia do rio Doce. Tanto os dados de entrada, quanto as ferramentas utilizadas, apresentaram diferenças quanto ao tempo de processamento e à facilidade de uso dos dados, fatos que devem ser considerados antes de um estudo, especialmente em bacias de médio e grande porte. ABSTRACT: This paper presents a comparative study about efficiency and effectiveness of different softwares to delimit hydrographic basin boundaries and to extract drainage network from altimetric data derived from three different sources: original SRTM images from USGS (90 meters), resized SRTM images from Topodata Project (30 meters) and ASTER images (30 meters). The computational tools used were ArcHydro module of ArgGis, the free software TerraHidro and the free module Hand, running at IDL plattaform. It was analyzed the facilities and difficulties of each altimetric data set, the processing times and the final products for the rio Doce basin case study. Both altimetric data and computational tools have showed differences referring to processing time and ease of use, aspects which may be consider within a project, especially in the case of medium and big basins. |
