Remote sensing is the technique of gathering data and information about an object or phenomenon without making direct contact with the studied entity. This technique has vast environmental applications, which facilitate investigations in the fields of hydrology, geology, glaciology, ecology, geography, etc. Remote sensing is divided into the two classifications of active and passive remote sensing. The different data acquisition techniques used for environmental remote sensing are hyperspectral imaging, geodetic remote sensing, radar, LIDAR, etc. This book elucidates new techniques and applications of environmental remote sensing and systems analysis in a multidisciplinary manner. It strives to provide a fair idea of this discipline and to help develop a better understanding of the latest advances within this field. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
