35 Chapter 5. Introduction to Remote Sensing What is Remote Sensing Remote Sensing is the science (and to some extent, art) of acquiring information about the Earth's surface without actually being in contact with it. This is done by Sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. In much of Remote Sensing , the process involves an interaction between incident radiation and the targets of interest. This is exemplified by the use of imaging systems where the following seven elements are involved. Note, however that Remote Sensing also involves the Sensing of emitted energy and the use of non-imaging sensors.
5.6 Passive vs. Active Sensing Remote sensing systems which measure energy that is naturally available are called passive sensors. P assive sensors can only be used to detect energy when the naturally occurring energy is available. For all reflected energy, this can only take specular and diffuse reflection .
