Chapter 5. Introduction to Remote Sensing
hillagric.ac.inChapter 5. Introduction to Remote Sensing 5.1 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.
