Remote sensing of the earth refers to the use of instruments carried on aircraft and earth-orbiting satellites that detect energy reflected or emitted from the earth's surface in different portions of the electromagnetic spectrum. Those who put their source of energy (a large “flashbulb”) are called an active system. Prior to the week focused on sensors and satellite types, I was unaware of the difference between a satellite and a sensor and how many different satellite missions actually … Resolutions of Remote Sensing 1. Remote sensing is obtaining information about an area or phenomenon through a device that does not touch the area or phenomenon under study. Your eyes are a good example of remote sensing instruments. Many remote sensing devices are onboard satellites that monitor the Earth from space.
