Methods for gathering data on a large or landscape scale which do not involve on-the ground measurement, especially satellite photographs and aerial photographs; often used in conjunction with Geographic Information Systems.

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance from the targeted area. Special cameras collect remotely sensed imagesof the Earth, which help researchers sense things about the Earth.
