Abstract

As the name suggests, remote sensing entails the use of sensing instruments for acquiring information remotely about an area of interest on the ground. The term “information” can refer to a wide variety of observable quantities (signals), such as reflected solar radiation across the electromagnetic spectrum and emitted thermal radiation from the earth’s surface as measured from handheld [1], airborne [2] or spaceborne imaging sensors [3, 4]; received back-scattered microwave radiation from radio detection and ranging (RADAR), synthetic aperture radar (SAR) [58] or light detection and ranging (LIDAR) [911] equipment; electrical conductivity as measured from airborne sensors, etc. Availability and effective exploitation of such data has facilitated advances in applied fields such as weather prediction, invasive species management, precision agriculture, urban planning, etc.
