Outline of Final Research Achievements

This study aims to develop a methodology of estimating land cover absorption characteristics using air bone hyperspectral imaging data. The hyperspectral imaging data was shot by CASI-3 of hyperspectral scanners that cover the visible and near infra-red parts of the spectrum. The shot area was Togo Field (Field Science Center, Nagoya University). The measurement of land cover absorption characteristics by the EA-noise method was conducted at the same time, as shooting hyperspectral imaging data. Then an estimating absorption model that is a multiple regression model with spectral reflectivity as explanatory variables and land cover absorption as objective variable is developed. As the result of verifying accuracy of the model, a good correlation between the estimated absorption and measured absorption was revealed.
