"...an essential read for anyone interested in high resolution spectral remote sensing... very interesting and stimulating..." -Paul R. Hays"...Our knowledge and monitoring capabilities about the state of the atmosphere would be much less without the wealth of remotely sensed data available today. This book, written by an experienced scientist who designed several spectral imagers that became operational on satellites, provides scientists and engineers with an in-depth understanding of the fundamental concepts of spectral imaging. ...I consider the book as a valuable reference for advanced users of data from spectral imagers."-Leopold Haimberger, Vienna
