Remote sensing

The process of using aerial sensor technologies to detect and classify objects on Earth both on the surface, and in the atmosphere and oceans by means of propagated signals.

Contributors in Remote sensing

Remote sensing

Absorptance

Earth science; Remote sensing

A measure of the ability of a material to absorb EM energy at a specific wavelength.

European Space Agency (ESA)

Earth science; Remote sensing

Based in Paris, a consortium between several European states for the development of space science, including the launch of remote-sensing satellites.

Mid-infrared (MIR)

Earth science; Remote sensing

The range of EM wavelengths from 8 to 14 micrometres dominated by emission of thermally generated radiation from materials; also known as thermal infrared.

Fovea

Earth science; Remote sensing

The region around that point on the retina intersected by the eye's optic axis, where receptors are most densely packed. It is the most sensitive part of the retina.

Multispectral scanner

Earth science; Remote sensing

Scanner system that simultaneously acquires images of the same scene at different wavelengths.

Charge-coupled detector (CCD)

Earth science; Remote sensing

A device in which electron are stored at the surface of a semiconductor.

Vector format

Earth science; Remote sensing

The expression of points, lines, and areas on a map by digitised Cartesian coordinates, directions, and values.
