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.

Disasters occur when two factors hazard and vulnerability coincide. The risk of a disaster occurring is proportional to the severity of the hazard and the vulnerability of the affected population. With human population continuing to increase, it is inevitable that more people will be living in hazardous settings, increasing the risk of disaster. With global warming and associated environmental instability, both the frequency and severity of disasters is likely to increase (van Aalst 2006). The United Nations (2005) Hyogo Framework for Action on disaster risk reduction asked governments to: ‘…promote the use, application ...
