Remote sensing systems do not function perfectly. Also, the Earth’s atmosphere and
surface (land and water) are complex and do not lend themselves well to being recorded by
remote sensing devices that have constraints such as spatial, spectral, temporal, and
radiometric resolution.
Consequently, error creeps (i.e., absorbed and scattered) into the data acquisition process
and can degrade the quality of the remote sensor data collected.
Therefore, this chapter reviews fundamental electromagnetic radiation principles.
