David Wilkie and John Finn present the methods and tecnology of remote sensing in a clear, readable form that lives up to its subtitle "A guide for first-time users". Both authors come to this technology from a background in resource management which provides them good insight into the specialized needs of biologists and planners. The discussion focuses on distinguishing vegetation types (and in some cases individual animals) rather than rocks and minerals, as in several other well-known texts. Discussions of sensor technology merge seamlessly with practical issues such as the statistical basis of sampling designs and the relative merits of aerial videography. Throughout, an effort has been made to compare all of the many platforms, services, and sensor types in straightforward tables showing their strengths and weaknesses. In short, the authors present the technology as a useful tool for people interested in environmental issues, rather than as a high-tech novelty of interest to electronic engineers. I have recommended the book to all of my graduate students.
