What Is Remote Sensing?
• Collecting information from a distance, by measuring energy coming from the target
– Energy reflected off the target from a natural source (sunlight)
– Energy reflected off the target from an artificial source (examples: sonar, seismic, radar)
– Energy emitted by the target (example: infrared “heat”)
