Generally denotes remote sensing in two or more spectral bands, such as visible and infrared.
Industry:Aerospace
Geometric irregularities on images that are not constant and cannot be predicted from the characteristics of the imaging system. For example: parallax distortions caused by topography.
Industry:Aerospace
height above a datum, the datum usually being mean sea level. Not the same as elevation, for altitude generally refers to points above the Earth's surface rather than those on it. Compare with elevation.
Industry:Aerospace
In an instrument such as the Enhanced Thematic Mapper Plus (ETM+), the plane occupied by the detectors, and on which the radiances to be sensed are incident.
Industry:Aerospace
In decimal systems kilo stands for 1,000, but in binary systems a kilo is 1,024 (2 to the 10th power). Technically a kilobyte is 1,024 bytes but is often used loosely as a synonym for 1,000 bytes. The term is commonly used to quantify the amount of a computer's core memory storage.
Industry:Aerospace
In image processing, a homogeneous group of units, which are very "like" one another. "Likeness" among units is usually determined by the association, similarity, or distance separating the measurement patterns associated with the units.
Industry:Aerospace
In image processing, the coordinate in n space (where n is the number of features, bands, or channels), determined by the intensity value of each band.
Industry:Aerospace
In reference to Landsat images, those scene data which have only been radiometrically, corrected through the ground processing system, labeled Level 1R or L1R data.
Industry:Aerospace
In reference to Landsat images, those scene data, which have been both radiometrically, corrected and geometrically corrected through the ground processing system, labeled “Level-1G or L1G” data.
Industry:Aerospace
In remote sensing, an area on the ground from which electromagnetic radiation is emitted or reflected. See instantaneous field of view (IFOV), resolution cell.
