Paper Abstract

Relatively little work has been performed to investigate the potential of polarization techniques to provide contrast enhancement information for vegetation mapping, and for vegetation condition assessment. Largely, this is because film is less accurate radiometrically than digital FPA sensing devices. Since polarization studies necessitate the differencing of images obtained with a linear polarizer rotated about the optic axis of a camera between sequential exposures, and since some of the differences are small, film has generally lacked the radiometric accuracy needed to reliably record such differences. Kodak has developed a high spatial resolution camera, and the development of linear drivers to read the data from the camera into the computer has resulted in a device which can be used as a multiband imaging polarimeter. Here we examine the potential of digital image acquisition as a potential quantitative method to obtain new information uncorrelated with that obtained by more conventional multiband imaging methods. Such information can potentially be used to form more sensitive vegetation indices, to differentiate species, and to penetrate canopy. We present promising examples of an active on-going research program.
