Remote sensing
ground-range image
Earth science; Remote sensing
Radar image in which the scale in the range direction is constant.
remote sensing
Earth science; Remote sensing
Collection and interpretation of information about an object without being in physical contact with the object.
cut off
Earth science; Remote sensing
The digital number in the histogram of a digital image which is set to zero during contrast stretching. Usually this is a value below which atmospheric scattering makes a major contribution.
additive primary colors
Earth science; Remote sensing
Blue, green, and red. Filters of these colors transmit the primary color of the filter and absorb the other two colors.
shuttle multispectral infrared radiometer (SMIRR)
Earth science; Remote sensing
A non-imaging spectroradiometer carried by the NASA Space Shuttle covering ten narrow wavebands in the 0. 5-2. 4 m range.
cross-polarized
Earth science; Remote sensing
Describes a radar pulse in which the polarization direction of the return is normal to the polarization direction of the transmission. Cross-polarized images may be HV (horizontal transmit, vertical ...
