Information can be gathered about an object, event or phenomenon without making direct physical contact with it. This is possible by applying the technology of remote sensing. Using satellite-based or aircraft-based sensor technology, objects on the Earth can be detected and classified. Data can be acquired from conventional radar, laser and radar altimeters, LIDAR, ultrasound and radar tide gauges, spectropolarimetric imaging, radiometers and photometers, etc. Remote sensing is useful in varied domains such as land surveying, hydrology, geography, ecology, glaciology, oceanography, etc. It also has commercial, economic, military, intelligence and humanitarian applications. This book unravels the recent studies in the field of remote sensing. Also included in this book is a detailed explanation of the different methods used for the analysis, interpretation and use of remote sensing data. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of study.
