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.

Introduction to Airborne Laser Scanning
A Short History of Airborne Laser Scanning

Airborne laser scanning (ALS) is a remote sensing technique used for mapping of topography, vegetation, urban areas, ice, and infrastructure. It is often referred to as light detection and ranging (lidar) because it uses a laser to illuminate the Earth's surface and a photodiode to register the backscatter radiation. Lasers were developed by the 1964 Nobel Prize winners Townes, Basov, and Prokhorov in 1958. Since 1960, when Theodore Maiman demonstrated that light amplification by stimulated emission of radiation (laser) is ...
