Stages in Remote Sensing

• Emission of electromagnetic radiation, or EMR (sun/self- emission)

• Transmission of energy from the source to the surface of the earth, as well as absorption and scattering

• Interaction of EMR with the earth's surface: reflection and emission

• Transmission of energy from the surface to the remote sensor

• Sensor data output
