Informationen zum Autor Samuel J. Purkis (PhD) is an Associate Professor at the National Coral Reef Institute, Nova Southeastern University Oceanographic Center, Florida, USA. Here, he directs a team focused on remote sensing solutions for the regional-scale appraisal of shallow-water tropical ecosystems. His experience in the Earth and Marine Sciences spans more than fifteen years and all of Earth's major coral reef provinces, ranging from ecological assessment, through sophisticated geostatistical modelling, to carbonate geology. Victor V. Klemas (PhD) is Professor Emeritus at the College of Earth, Ocean and Environment, University of Delaware. Since 1976 he has directed the university's Center for Remote Sensing, where he has pioneered the application of a wide range of remote sensing techniques to studies of wetland and estuarine ecosystems along major coasts of the world. He has served on six scientific committees of the National Research Council (NAS) and various government advisory panels. Klappentext Remote Sensing plays a key role in monitoring the various manifestations of global climate change. It is used routinely in the assessment and mapping of biodiversity over large areas, in the monitoring of changes to the physical environment, in assessing threats to various components of natural systems, and in the identification of priority areas for conservation. This book presents the fundamentals of remote sensing technology, but rather than containing lengthy explanations of sensor specifications and operation, it concentrates instead on the application of the technology to key environmental systems. Each system forms the basis of a separate chapter, and each is illustrated by real world case studies and examples. Readership The book is intended for advanced undergraduate and graduate students in earth science, environmental science, or physical geography taking a course in environmental remote sensing. It will also be an invaluable reference for environmental scientists and managers who require an overview of the use of remote sensing in monitoring and mapping environmental change at regional and global scales. Zusammenfassung This book provides the reader a broad grounding in the science of Earth Observation (EO) of our changing planet. It contains a comprehensive sequenced discussion covering the significant themes of global change! their cause! and how they can be monitored through time. Inhaltsverzeichnis Preface.
