Outline of Final Research Achievements

In this study, we analyzed the forest decline using the hyper spectral camera on the forest stand in which trees were wilted artificially. The change of wilting tree on early stage is difficult to be found on visible band data, but it can be found on hyper spectral data in previous research. By adapting this method to remote sensing, the early detection of forest decline on wide area is implemented. On the observation at the test sites, the effects of change of sunshine had bad impact to the analysis of the spectral data and we need to develop the method for calibration. We make a success of the development and the base of observation method for the forest decline using the hyper spectral camera is strengthened.
