"Introduction to Remote Sensing" by James Campbell covers Remote Sensing, past and present, from one end of the spectrum to the other. Head of the Geography Department at Virginia Tech, his book shows all of the new technology and image processing required for todays sensors. It has excellent illustrations and charts to get the point across easily for a very difficult subject. Complete and up to date, Campbell discusses the new wave of remote sensing, image classification, plant sciences, earth sciences, gps, hyperspectral data, the history of satellites, radiation and cartography. And most of all, how to apply it accurately.
This book illustrates the authors vast and broad knowlegde on the subject. Even though the level of detail sometimes is high, it never obscures the issue. The book is easy to read, and interesting for anyone who want to learn (more) about Remote Sensing. Also it works very well as a solid foundation for anyone with interest in the expanding field of GIS. The paperback itself is of very high quality, unlike so many other books who just dissolves in your hands. My personal opinion is that it could be more mathematical, but I know I am a minority. This book is highly recommended to University-courses on both this subject an GIS.
