Remote sensing and its kindred technologies, such as geographic information systems (GIS) and the Global Positioning System (GPS), are having a pervasive impact on the conduct of sciences, government, and business alike. This book is designed to be primarily used in two ways: as a textbook in the introductory courses in remote sensing and image interpretation, and as a reference for the burgeoning number of practitioners who use geospatial information and analysis in their work. Because of the wide range of academic and professional settings in which this book might be used, we have made the discussion discipline neutral.In short, anyone involved in geospatial data acquisition and analysis should find this book to be a valuable text and reference.
