Remote sensing can be defined as the art, science, and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting imagery and digital representations of energy patterns derived from noncontact sensors. Some definitions make specific references to the types of sensors and the wavelengths of electromagnetic radiation involved. Classic fields of application are topographic and thematic mapping, meteorology, climatology, oceanography, hydrology, and geology. New application fields include 3D mapping and environmental monitoring, as well as assessment and management support for catastrophic events.

The Electromagnetic Spectrum Used for Remote Sensing

The fact that elements have a characteristic interaction with electromagnetic radiation is used to build remote sensors. Every sensor is made of chemical elements that are sensitive to ...
