Explanation:
Detailed explanation-1: -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".
Detailed explanation-2: -There exist two main types of remote sensing classified according to the source of signal they use to explore the object, active vs. passive. Active remote sensing instruments operate with their own source of emission or light, while passive ones rely on the reflected one.
Detailed explanation-3: -There are three broad categories of remote sensing platforms: ground based, airborne, and satellite.
