Active and Passive Remote Sensing - University of Rhode Island
www.edc.uri.edu1 Active and Passive Remote Sensing Passive remote sensing systems record EMR that is reflected (e.g., blue, green, red, and near-infrared light) or emitted (e.g., thermal infrared energy) from the surface of the Earth. Active remote sensing systems are not dependent on the Sun’s EMR or the thermal properties of the Earth.
