The science and technology of environmental remote sensing refers to the use of aircraft- and satellite-based sensors to gather information about the Earth's atmosphere, oceans, glaciers, etc. It is different from on-site observation, as it does not include making physical contact with the observation site or the object of study. This technology is mostly used in conducting land surveys and guiding investigations in the fields of geology, ecology and hydrology. The different tools of environmental remote sensing are light detection and ranging (LIDAR), laser and radar altimeters, hyperspectral imagers, ultrasound and radar tide gauges, sonar, etc. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the environmental applications of remote sensing. Also included herein is a detailed explanation of the various concepts and applications of environmental remote sensing. This book is a vital tool for all researching and studying this field.
