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.

Prior to the development of digital elevation data, contour lines derived from remote sensing and drawn on paper maps were the main form of elevation data around the world. In many areas, contour lines remain the most common format for elevation data. Replacement of planetable surveying by aerial photogrammetry in the United States started in the 1940s (USGS 2005). Since then, airborne and later spaceborne remote sensing has become the dominant information source for elevation, using various technologies such as stereoscopic photogrammetry (Giles and Franklin 1996), interferometric radar (Rabus et al. 2003), or laser scanning (French 2003, ...
