| Abstract | The Airborne Hyperspectral Scanner (AHS) was used to acquire images with 2.5 m spatiala resolution in the visible, near infrared and thermal spectral regions over an olive orchard in Cordoba (Spain) to study the spatial and temporal variability of water stress. The AHS thermal information enabled obtaining surface temperature images of the orchard at 7:30, 9:30 and 12:30 GMT in 25 july 2004. The experimental design consisted of applying three different irrigation treatments in randomly selected blocks during july, august and septemper, acquiring measurements of leaf water potential, stomatal conductance and photosynthesis to study the water stress effects on the trees. Infrared sensors IRT placed on top of the trees allowed to obtain continuously temperature measurements, providing validation data for the airborne thermal imagery. Results of this study are presented, suggesting that hyperspectral and high resolution remote sensing methods have important applicability in precision agriculture for management of controlled deficit irrigation methods. |
