Remote sensing

thermal IR

Earth science; Remote sensing

IR region from 3 to 14 m that is employed in remote sensing. This spectral region spans the radiant power peak of the earth.

airborne visible and infrared imaging spectrometer (AVIRIS)

Earth science; Remote sensing

Experimental airborne along-track multispectral scanner under development at JPL to acquire 224 images in the spectral region from 0. 4 to 2. 4m.

edge

Earth science; Remote sensing

A boundary in an image between areas with different tones.

Earth satellite orbit in which the orbit plane is nearly polar and the altitude is such that the satellite passes over all places on earth having the same latitude twice daily at the same local sun ...

Mie scattering

Earth science; Remote sensing

The scattering of EM energy by particles in the atmosphere with comparable dimensions to the wavelength involved.

picture element

Earth science; Remote sensing

In a digitized image, the area on the ground represented by each digital number. Commonly contracted to pixel.

foreshortening

Earth science; Remote sensing

A distortion in radar images causing the lengths of slopes facing the antenna to appear shorter on the image than on the ground. It is produced when radar wavefronts are steeper than the topographic ...
