What is Remote Sensing?

Astronomers observe and explore the universe with its planets, stars and other celestial bodies from earth. In remote sensing the situation is similar: Objects are observed from afar without making direct contact. However, in remote sensing the universe is not the object of study but the earth itself!
In order to observe and explore the surface of the earth, measuring devices – so-called sensors – are being attached to aircraft and satellites. Sensors detect electromagnetic waves and store them as image data, so the scientist can analyse the data while sitting in the office. But what is the use of it? Find out here.

 

Prozesskette der Fernerkundungsaufnahme

Process chain of an image acquisition process in remote sensing: Sunlight reflected by the surface of the earth is measured by a remote sensing sensor, the data are stored and then analysed by a scientist.
