Image corrections
-
Proces of geometric correction
Imagery is projected to a plane using map projection and datum, coarse DEM applied to normalize for topographic relief
Image sharpening methods
4-band pan sharpened imagery available.
Sensor corrected
Y
Radiometrically corrected
Y
Process of radiometric and/or atmospheric correction
A relative radiometric correction is performed on raw data from all detectors in all bands during the early stages of WorldView-3 product generation. This correction includes a dark offset subtraction and a non-uniformity correction (e.g. detector-to-detector relative gain).
