Remote Sensing of the Environment

Remote sensing is the science of obtaining and interpreting information from a distance, using sensors that are not in physical contact with the object being observed.  The science of remote sensing in its broadest sense includes aerial, satellite, and spacecraft observations. Remote sensing of the Earth has many purposes, including making and updating planimetric maps, weather forecasting, and gathering military intelligence.
