Chapter 5. Introduction to Remote Sensing

Chapter 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.

Chapter 7 84 Introduction To Remote Sensing

Introduction To Remote Sensing e. Detection of Reflected/Emitted Energy by the Sensor: The sensors recording the energy that they receive are placed in a near– polar sun synchronous orbit at an altitude of 700 – 900 km. These satellites are known as remote sensing satellites (e.g. Indian Remote Sensing Series).

PRINCIPLES OF REMOTE SENSING

Indian Institute of Remote Sensing, Dehra Dun Abstract : Remote sensing is a technique to observe the earth surface or the atmosphere from out of space using satellites (space borne) or from the air using aircrafts (airborne). Remote sensing uses a part or several parts of the electromagnetic spectrum.
