Remote Sensing

Optical and Infrared Remote Sensing

uses satellites with optical sensors to detect solar radiation reflected or scattered from the earth and thus develop images of Earth.

Remote sensing

a technology to gather information and analyzing an object or phenomenon without making any direct contact

Remote sensing satellites

Satellites equipped with sensors that observe the earth and collect remote sensing data

spectral signatures

defined as the unique pattern of wavelengths radiated by an object

signature

Any remotely sensed parameter, which directly or indirectly characterizes the nature and/or condition of the object under observation
