Abstract
In 2010, a Specim AISA Eaglet sensor was flown by helicopter over a site on the island of Hawaii. Ground data of tree locations and foliar chemistry were taken the previous fall. Acacia koa (A.koa), trees native to Hawaii, were found to have a distinct spectral feature at approximately 450nm. A continuum removal process was developed for the remotely sensed hyperspectral data which accentuates this unique feature and differentiates A.koa from Douglar-fir and Cryptomeria japonica. A unique enhancement of reflection was detected at 0.5 m in the Cryptomeria japonica arising from the structural creation of a bowl shaped feature that was confirmed with high resolution lidar.
