CHARACTERIZATION OF THE SOIL - PLANT CONDITION WITH HYPERSPECTRAL ANALYSIS OF THE LEAF AND LAND SURFACE

The Hungarian Institute of Agricultural Engineering (HIAE) has a high-quality remote sensing device, the AISA DUAL hyper-spectral sensor. The device’s sensor operates in the range of 400-2400 nm wavelength and has a high, 1 nm sensitivity inside the visual spectrum. By using the hyper-spectral remote sensing method, the colour values can be calculated to a high level of accuracy and the spatial distribution can also be determined. In the case of the soil and the plant leaves it can be stated that the contents can better be determined by integral optical characteristics (for example: colour), rather than by differentials. High resolution photographs have been taken from the air of a ploughland situated near Bábolna by this instrument, and their colour attributes have been determined. There is a significant connection between the integral optical characteristics, the colour values and the contents of the soil and plant leaves.
