Remote Sensing 08
Remote Sensing 08 : The acquisition and interpretation of images of the Earth's surface, where images are usually acquired by cameras and scanners carried on aircraft or orbiting satellites. Optical images simultaneously record visible and invisible reflected light in several different wavelengths; when combined, these images (or 'bands') can be used to map burn scars, different types of fuel and fuel moisture. Thermal images record emitted heat from active fires and the Earth's surface. Radar remote sensing uses artificial microwave energy to produce images of burn scars through cloud and at night
