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.

Remote Sensing of Soils
soils, remote sensing, inference, SAR, thermal infrared, aerial photography.
The Earth's soils form essential components of natural ecosystems, and the basis for production of food, fuel, and fiber. Use and preservation of these resources requires effective monitoring and management, which in turn depends upon preparation of accurate maps of soil distributions, and monitoring of temporal variations in soil status. It is in this context that remotely sensed imagery forms an essential tool for acquiring data representing soil distribution, and recording both temporal and spatial variation of soil properties.
Soil is formed from weathered organic and mineral debris at the Earth's surface, as modified over time by weather and climate. At any specific place, its characteristics are the result of ...
