Hyperspectral remote sensing-An advance tool in physiological research

The recent developments in hyperspectral remote sensing hold a major role in estimating physiological parameters with less involvement of cost, time and labour. Quick detection of a physiological parameter can help to reduce the impact of any damages on crop growth and yield. The works relevant to spectral response on different physiological parameter are dealt with in this paper. It was observed from the spectral data analysis that the physiological parameter related to growth and morphology, water related parameter, biochemical and physiological processes can be precisely estimated using hyperspectral remote sensing approach. The study also elucidates that hyperspectral techniques can lead to the development of real-time crop management, thereby reducing the yield losses.
