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.
