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.

By the year 2007, more than half of the world's population lived in urban areas (United Nations 2006) and trends suggest the number of urban dwellers will rise to almost 5 billion by 2030, out of a world total of 8.1 billion. This rapid urbanization is a global phenomenon giving rise to a variety of social and environmental problems which affect cities in developed and developing worlds somewhat differently. In the developing world, socio-economic problems resulted in over 1 billion people living in urban slums by 2007 (United Nations 2006), whereas in affluent cities the quality of the urban environment is of greater concern.
