-- TexasView Remote Sensing Consortium Research Award 2005, $5,000 (PI: Hongjie Xie)

Satellite-based hyper-spectral imaging technology provides potential possible to identify the real oak wilt center in its early stage with high spatial (meters), temporal (days or half a month), and spectral resolution (10 nanometer) capability. The awareness of early stage of oak wilt (usually red oak) center makes it easier, effective, and inexpensive for treatment. To study the potential capability of hyper-spectral technology for early oak wilt detection, we need to establish a spectral library of oak trees in different stages of development from healthy, early stage, middle, to final stage of oak wilt.
