Introduction
There is an increasing demand for accurate, timely information on environmental and natural resources, including spatial relationships and temporal changes and trends, local to global. Remote sensing is the science of observing and collecting information on objects, areas or events without being in direct or physical contact with them (remote = far away, from a distance). Advantages of this technology are:
- Observation of a large geographical area
General principles
Types of sensors
Effects of atmosphere
Applications
Definition of Remote Sensing:
In the broadest sense, remote sensing is the measurement or acquisition of information of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. In practice, remote sensing is the utilization at a distance (as from aircraft, spacecraft, satellite, or ship) of any device for gathering information about the environment [1].
This is the common definition for Remote Sensing, other definitions can be discussed in the article
