Remote Sensing is the science of gathering information about an area from a distance. Special cameras on satellites or aircraft collect images of the Earth’s surface from a distance by measuring the reflected or emitted radiation. 

Remote sensing helps researchers monitor environmental changes like land use, vegetation cover, waterbodies and natural disasters like wildfires, floods and droughts.Remote sensing also aids in agriculture, urban planning, climate change studies, and archaeological surveys, among other applications.

Remote sensing allows monitoring changes on Earth over a long period since satellites have been recording images of the Earth since 1975.
