Remote sensing acquires and interprets small or large-scale data about the Earth from a distance. Using a wide range of spatial, spectral, temporal, and radiometric scales remote sensing is a large and diverse field for which this Handbook will be the key research reference. Illustrated throughout, an essential resource for the analysis of remotely sensed data, The SAGE Handbook of Remote Sensing provides researchers with a definitive statement of the core concepts and methodologies in the discipline.

Optical imaging sensors are a key technology in the field of remote sensing. Nearly all applications of remote sensing rely on optical imagery as a primary data source for analysis. The interpretation of visible images is as intuitive for remote sensing analysts as looking at a photograph. This comfort and reliance on optical imagery comes naturally as the very first remote sensing instrument was the human visual system. The human eye collects light in the visible optical spectrum and records the intensity with rods and cones on the retina. Optical remote sensing systems in use today operate with many similar components to the human visual system but provide dramatically richer information through higher resolution and ...
