Abstract:
Visible-Near InfraRed (VNIR) and Thermal InfraRed (TIR) simultaneous information is crucial in order to carry out a reliable description of crop water stress condition. In this paper, a study based on the hyperspectral sensors TASI and CASI, which are regularly operated by the Institut Cartogràfic de Catalunya (ICC) since 2009, is proposed. High-resolution hyperspectral data sets acquired over a vineyard in Raïmat (Spain) are employed to characterize the energy flux exchange between surface and atmosphere, and to estimate the crop daily evapotranspiration (ETd). Finally, a relative Crop Water Stress Index (CWSI) is obtained under specific assumptions upon the water stress condition of reference plants within the imaged scene.
