sensor SEAWIFS
AbstractAtualmente existem uma diversidade de satélites de recursos naturais, que carregam a bordo sensores multiespectrais, que fornecem dados que podem ser utilizados de várias formas. Dentre estes sensores destaca-se Sea-viewing Wide Field-of-view sENSOR (seaWIFS), que está a bordo do satélite Seastar e foi concebido para examinar os fatores biogeoquímicos que afetam as mudanças climáticas globais. As imagens deste sensor se encontram disponíveis no formato Hierarchical Data Formal (HDF), que a NASA definiu como padrão para amarzenar e disseminar os dados dos novos sensores sob sua responsabilidade. A falta de uma ferramenta para manipular dados do sensor SeaWIFS na plataforma PC/Windows motivou a execusão deste trabalho. Assim, apresenta-se uma ferramenta, WinSWHDF, para extrair e processar os dados provenientes deste sensor. Devido a característica da variedade de dados gerados pelo sensor SeaWIFS, o formato HDF é capaz de acomodar essas informações de forma organizada e confiável. A ferramenta desenvolvida, é capaz de extrair não só as imagens, mas também os dados de navegação para possibilitar a conversão para a projeção cilíndrica equidistante. Na correção radiométrica foi implementado somente a correção devido a degradação dos detectores do sensor com o tempo. Além disso, a ferramenta oferece a opção de realizar a correção atmosférica. O WinSWHDF foi desenvolvido em ambiente Windows possuindo recursos de visualização e processamento de imagens, composição de mosaicos e a sobreposição do contorno político do Brasil e de seus estados. A ferramenta desenvolvida permite gerar vários produtos para diferentes áreas de pesquisa. Implementou-se também nesta ferramenta, rotinas para o cálculo do índice de vegetação por diferença normalizada (IVDN) para estudo da cobertura vegetal, que foi utilizado para a avaliação dos dados SeaWIFS. ABSTRACT: Currently exist a diversity of earth Observation satellites, that carry on board a variety of multispectral sensors, providing data that can be used in serveral forms. Amongst these sensors we can mention the Sea-viewing Wide Field-of-view Sensor (SeaWIFS), which is on board the Seastar satellite and was conceived to study biogeochemicastry factors that affect global climate changes. The data from this sensor ae available in Hierarchical Data Format (HDF), that NASA defined as the standard formart for storage and distribution of the data from new sensors under its responsibility. The lack of tools to manipulate data from SeaWIFS in the PC/Windows platform motivated the development of this work. Then work describes a tool for extracting and processing the data acquired by this sensor. Due to the characteristic of the variety of the data from this sensor , HDF is capable to accomodate these information in an organized and reliable form. The developed tool, Win SWHDF, is capable to extract the images, and also the navigation and calibration information, which are used in their geometric and radiometric corretions. For the geometric corretion, a navigation algorithm was implemented to make possible the conversion, a equidistant cylindrical projection. The radiometric correction is performed to compensate the degradation of the sensor's detectors. Moreover, the tool offers the option to apply the atmospheric corretion. The WinSWHDF was developed in Windows platform providing resources of images visualization and processing composition of mosaics and the overlapping of the political contour of Brazil and its States. The developed tool allows to generate some products for different research areas. For this work, the Normalized Difference Vegetation Index (NDVI) to study vegetation cover was generated in oder to evaluate the SeaWIFS data.
