Advancement in sensor technology, processing algorithms, and computational capacity in the last decade have taken remote sensing to a level where observations can be turned to quantitative measurements, and the technology can be used in near real-time for mapping, monitoring and decision-making. The third edition of this widely acclaimed book has been fully revised and updated. It covers remote sensing in a wide range of the electromagnetic spectrum, from local to global scales, with rich application examples from across the globe. It presents the state-of-the-art content in areas of atmospheric interactions, spectroscopy, predictive modeling, multi-sensor data integration, and mapping Earth surface composition and change. The subject matter is presented at a basic level, serving students as an introductory text on remote sensing. The main part of the book will also be of great value to active researchers.
