Remote sensing techniques are used in acquisition of real-time data from all accessible and inaccessible locations mapped over time and space. The use of remote sensing technology for the topographical mapping of wildlife populations, natural resources, vulnerable ecosystems and pollution provides valuable data for environmental management and monitoring. Remote sensing has also been incorporated in the study of fields like forestry, climatology, glaciology, hydrology and geology. This book explores the applications of remote sensing in environmental studies and conservation efforts. It also presents the effective techniques of incorporating sensor data to make the studies more relevant and informative. It will benefit researchers and students alike.
