Book excerpt: A comprehensive introduction to the principles and applications of remote sensing, written by contributors actively involved in optical remote sensing research. Special attention is paid to the interrelationship between land surfaces and the intervening atmosphere. Focusing specifically on the spectral region of 0.04 to 16 microns, this book covers a wide range of techniques and their practical implementations. Demonstrates how the same basic measurements can be used in several different applications to obtain quantitative measurements.
