Resumo: | The mapping of the Brazilian territory does not have full coverage. One way to solve this gap is through the use of satellite images. One of these products are the images SRTM (Shuttle Radar Topography Mission), which have very important information for environmental studies. Yet still lacks theoretical foundation regarding the reliability of this basemap. Thus, this study aims to compare the information on SRTM altimetry in the images with the information contained in topographic maps made by the brazilian army in the 70s. Was studied the watershed Arroio do Veado located between the cities of Santa Maria and Silveira Martins, in the transition zone between Central Depression and Serra Geral Plateau, in the Rio Grande do Sul state, southern Brazil. Using the ArcGIS software were extracted contour lines that served as bases and then generated the digital terrain model and slope map of the basin. It was observed that the data resulting from the two cartographic databases are very similar using a map scale 1: 50 000 applied to watersheds with one area circa the 4,000 hectares. Was concluded, with these conditions may be used SRTM images, useful, handling and wide coverage in Brazil. |

Uma forma de equacionar esta lacuna é através do uso de imagens de satélites. Um destes produtos são as imagens SRTM (Shuttle Radar Topography Mission), as quais possuem informações importantíssimas para estudos ambientais de escoamento superficial e fluxo subterrâneo. Ainda se carece de embasamento teórico quanto à confiabilidade desta base cartográfica. Nesse sentido, este trabalho objetiva comparar as informações referentes à altimetria presente nas imagens SRTM com informações contidas nas cartas topográficas. Essas foram confeccionadas pelo exército na década de 70, aplicados na bacia hidrográfica do Arroio do Veado, localizada entre os municípios de Santa Maria e Silveira Martins, na zona de transição entre a Depressão Central e o Planalto da Serra Geral, no Estado do Rio Grande do Sul, Brasil. Utilizou-se o programa ArcGIS extraindo-se as curvas de nível, as quais serviram de base, gerando-se o modelo numérico do terreno/MNT e mapa de declividade da bacia. Observou-se que os dados resultantes nas duas bases cartográficas são muitos semelhantes na escala 1:50.000 e bacia hidrográfica até 4.000 hectares. Conclui-se que nessas condições podem-se utilizar imagens SRTM, uma vez que apresentam facilidade de manuseio e ampla cobertura no país.Universidade Federal de Santa Maria2013-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/reget/article/view/916810.5902/223611709168Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 15, N. 15, AUG.-OCT., 2013; 3005-3011Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 15, N. 15, AGO.-OUT., 2013; 3005-30112236-11702236-1170reponame:Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/reget/article/view/9168/pdfLöbler, Carlos AlbertoSsccoti, Anderson Augusto VolpatoTerra, Lueni GonçalvesErtel, TiagoSilva, José Luiz Silvério dainfo:eu-repo/semantics/openAccess2021-07-14T13:02:59Zoai:ojs.pkp.sfu.ca:article/9168Revistahttps://periodicos.ufsm.br/regetPUBhttps://periodicos.ufsm.br/reget/oaimarcelobdarosa@gmail.com||reget.ufsm@gmail.com2236-11702236-1170opendoar:2021-07-14T13:02:59Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET) - Universidade Federal de Santa Maria (UFSM)false |
