3.3. Espectroscopia de Imageamento

A espectroscopia de imageamento (ou sensoriamento hiperespectral) consiste na obtenção de imagens em centenas de bandas espectrais (de largura nanométrica) e de forma contínua no espectro, como resposta à interação da energia eletromagnética com os alvos, seja ela refletida ou emitida (Goetz, 2009; Kruse, 2012).

Os sensores hiperespectrais proporcionam melhores resultados e produzem informações mais robustas, uma vez que fornecem um espectro de reflectância contínuo para cada pixel na cena. Imageadores hiperespectrais, frequentemente disponíveis em plataformas aéreas (e.g. ProSpecTIR – VS, HyMap, AVIRIS), fornecem imagens com maior resolução espacial e espectral em relação a sensores orbitais (Zomer, 2009), o que permite a detecção, mapeamento e caracterização direta de HCs ao invés da classificação de efeitos secundários de alteração. Em função da elevada resolução espectral destes sensores, os dados obtidos a partir das imagens podem ser comparados diretamente com dados de bibliotecas espectrais geradas em campo ou laboratório, viabilizando assim a utilização de algoritmos de desmistura espectral para a classificação das imagens.

Considerando o elevado potencial do imageamento hiperespectral, as imagens aqui obtidas com a estação de imageamento espectral automatizada (SisuROCK) no micro- experimento de impregnação, somadas às imagens adquiridas com o sensor hiperespectral aerotransportado (ProSpecTIR-VS) no macro-experimento, foram submetidas ao pré- processamento com wavelets e ao processamento digital de imagens com a utilização de algoritmos de classificação, respectivamente. Os endmembers utilizados para a classificação foram extraídos das bibliotecas espectrais de referência geradas nesses experimentos.

O objetivo do uso desta técnica foi o desenvolvimento de métodos de identificação e mapeamento remoto de regiões continentais afetadas por exsudações naturais ou vazamentos de petróleo, bem como a demonstração do potencial das bibliotecas espectrais geradas para a utilização em processamentos com algoritmos de classificação e desmistura espectral.
