  • SPECTRAL ANALYSIS METHOD FOR DETERMINING CHLOROPHYLL CONCENTRATION
    Publication number: 20100290031
    Abstract: The invention relates to a method and a device for determining a predefined spectral range, particularly the spectral range around the red edge. In said method, the analysis of the spectral range is carried out by means of two overlapping spectral value functions. The invention also relates to a method and a system for characterizing existent vegetation.
