New remote sensing methods based on narrow-band hyperspectral instruments enable the estimation of vegetation biophysical parameters and leaf biochemicals used to detect nutritional and water stress condition. This paper summarizes new advances in hyperspectral and thermal remote sensing for vegetation monitoring through biochemical and biophysical(More)
It has been demonstrated that the spectrum of fluorescence emission is dependent on leaf temperature, thus there is a need for thermal information in order to interpret fluorescence signals. Temperature is also related to transpiration and stomata closure, which affects C02 uptake and fluorescence. Therefore temperature measurements help to confirm the(More)
— Efficient water management in agriculture requires accurate estimation of the evapotranspiration (ET) of crops. This work presents the progress made on assessing the water status and ET estimation on discontinuous crop canopies where soil and shadow components affect the remote sensing imagery used. Two orchards used to conduct regulated deficit(More)
A technique is presented for detecting vegetation crop nutrient stress from hyperspectral data. Experiments are conducted on peach trees. It is shown that nutrient deficiencies that caused stress can be detected reliably on hyperspectral spectra. During an extensive field campaign, foliar and crown reflectance has been measured with a portable field(More)
