A leading text for undergraduate- and graduate-level courses, this book introduces widely used forms of remote sensing imagery and their applications in plant sciences, hydrology, earth sciences, and land use analysis. The text provides comprehensive coverage of principal topics and serves as a framework for organizing the vast amount of remote sensing information available on the Web. Featuring case studies and review questions, the book's 4 sections and 21 chapters are carefully designed as independent units that instructors can select from as needed for their courses. Illustrations include 29 color plates and over 400 black-and-white figures. New to this edition: * reflects significant technological and methodological advances * chapter on aerial photography now emphasizes digital rather than analog systems * updated discussions of accuracy assessment, multitemporal change detection, and digital preprocessing * links to recommended online videos and tutorials. This book will be important reading for students in a variety of disciplines, including geography, forestry, hydrology, and planning; also of interest to professionals who utilize remotely sensed data. It will also be a core text for undergraduate- and graduate-level remote sensing courses.
