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.

Reflectance spectra have been used since the beginning of the remote sensing era to obtain information about the composition of materials and features on the Earth's surface. Traditionally, most operational-as well as research-based spaceborne sensors only acquire relatively broad bandwidth multispectral data. Nevertheless, the development of hyperspectral sensors has demonstrated that the information content of high spectral resolution data is particularly useful for identifying surface mineralogy. Since imaging spectroscopy has important commercial applications in mineral resource exploration, many nations and private companies have developed airborne and satellite hyperspectral systems (e.g., Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) ...
