Resumo: | The particularities of the remote sensing instruments, even when they have the same characteristics, made the images generated, different among themselves. With that in mind, the goals of this work were to analyze the applicability and the limits of detection in the identification of natural targets in different satellite images. The area of study is located in Onda Verde in the state of São Paulo. The natural targets were selected from the analyses taken of the images and in the field trip. The images chosen presented the best contrast with the surroundings and easy to locate in the satellite images. For the digital processing of them the free software gvSIG was used. In this study, data of the mean spatial resolution satellite images were used such as Landsat-5, CBERS-2B e IRS-P6, available in the public domain database of the INPE (Instituto Nacional de Pesquisas Espaciais) and images of high spatial resolution of the satellites RapidEye and WorldView-2. In the mean spatial resolution sensors, the smallest spatial resolutions of the TM and LISS-3 sensors didn't interfered the visualization of the spectral targets analyzed, since the CCD have the higher spatial resolution, it wasn't possible the identification of the selected targets. The high spatial resolution images RapidEye and WorldView-2 showed great levels of details for the land cover, hence the high radiometric resolution of these satellites. |

Visando isto, o objetivo do trabalho foi analisar a aplicabilidade e os limites de detecção na identificação de alvos naturais em diferentes imagens de satélites. A área de estudo está localizada no Estado de São Paulo dentro do Município de Onda Verde, os alvos naturais foram selecionados a partir de análises realizadas nas imagens e visita desses pontos em campo. Foram escolhidas áreas que apresentaram bom contraste com o entorno e fácil localização nas imagens de satélite. Para o processamento digital de imagem foi utilizado o software livre gvSIG. Neste estudo foram empregados dados de satélites de média resolução espacial como Landsat-5, CBERS-2B e IRS-P6, disponíveis na base de dados de domínio público do INPE (Instituto Nacional de Pesquisas Espaciais) e imagens de alta resolução espacial dos satélites RapidEye e WorldView-2. Nos sensores de média resolução espacial, as menores resoluções espaciais dos sensores TM e LISS-3, não impediram a visualização dos alvos espectrais analisados, visto que, no CCD que possui uma maior resolução espacial, não foi possível a identificação dos alvos escolhidos. As imagens de alta resolução espacial RapidEye e WorldView apresentaram grande riqueza de detalhamento para a cobertura do solo, a isto atrela-se a alta resolução radiométrica desses satélites.Universidade Federal do Rio de Janeiro2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/785810.11137/2016_1_13_22Anuário do Instituto de Geociências; Vol 39, No 1 (2016); 13-22Anuário do Instituto de Geociências; Vol 39, No 1 (2016); 13-221982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7858/6339Copyright (c) 2016 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Gustavo Ferreira deGutierrez, Lorena Avelina RojasBarbassa, Ademir PaceliPereira, Luciana EscalanteCândido, Anny Keli Aparecida AlvesMarcato Júnior, JoséOliveira, José Renato Silva deParanhos Filho, Antonio Conceição2017-02-15T18:21:34Zoai:www.revistas.ufrj.br:article/7858Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T18:21:34Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false |
