This comprehensive introductory text presents an up-to-date overview of the most widely used forms of remote sensing imagery and their applications in plant sciences, hydrology, earth sciences, and land use analysis. Completely revised and updated, the second edition includes up-to-date coverage of the recently declassified CORONA imagery and other topics of current significance, and new chapters on hyperspectral remote sensing and global remote sensing. In addition, there is now a chapter on digital remote sensing featuring an essential discussion of the use of the Internet in remote sensing and including a list of relevant World Wide Web addresses. Ideal for both undergraduate and graduate use, the volume is designed to enable instructors to select and alter the sequence of chapters to meet the requirements of their courses.
