Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). The amount of radiation that an object reflects is the physical basis of remote sensing. Special sensors collect information about the reflected energy, and processing facilities turn it into a format that anyone can use. Large forest fires can be mapped from space Tracking clouds to help predict the weather Tracking the growth of a city and changes Discovery and mapping of rugged topography Tracking land cover type changes Structural Health Monitoring and Bridge Monitoring (High Spatial Resolution and Low Temporal Resolution) Monitor Structure Cracks Monitor Roof Cover Monitor Displacements Vertical (Land Subsidence) Horizontal (Landslide)
