Define the term remote sensing, and explain whether GPS and GIS are considered examples of remote sensing, and why. (Think about ways in which satellite imagery can be used to track changes on Earth's surface.)
Remote sensing is the process of gathering information about the earth without actually coming into contact with the features on ground. Remotely sensed data are obtained by means of orbiting satellites that are moving round the earth.
Geographic information systems is a broad category that describes the process of gathering, storing, analyzing and presenting geographical data.
A remote sensing unit and GPS device are components of the GIS framework.
Also, there is a software where the data gathered by a GPS and remote sensing units are interpreted for use.
