Hyperspectral Remote Sensing

Description

The book comprises various aspects of design of hyperspectral sensors and their trade off, described many of the international sensors flown on-board different space missions and also indigenous efforts made in the development of aerial hyperspectral sensor. Various image processing techniques used in the analysis of hyperspectral data are discussed. Review specific algorithms developed to improve spectral discrimination from Indian hyperspectral data. Use of hyperspectral data in the discrimination of crops, quantitative estimation of biophysical parameters and in understanding and detection of abiotic and biotic stress in vegetation through a number of case studies. How rapid and reliable assessment of various soil characteristics using hyperspectral data in conjunction with laboratory-measured spectra can be done to facilitate mapping of soils has been discussed. A radiative transfer model to simulate the effects of inelastic scattering on upwelling radiance in coastal and turbid waters using narrow band data has been discussed. Hyperspectral remote sensing has proved to be an extremely powerful tool in the exploration of planetary surfaces. These articles together provide a snapshot of the work happening in this field in the country and the trends. Considering that there will be Indian earth observation missions carrying full-fledged hyperspectral sensors in the near future and Chandrayaan-2 and possibly other planetary missions at the anvil, this compilation of review articles should be useful to a large community of researchers.
