  • Dynamic range of RGB image [bit depth]
    16
  • Data formats of imagery
  • Resolution of RGB imagery [best GSD in meters]
    0.3
  • Resolution of other bands [GSD in meters]
    1.2
  • Geolocation accuracy [CE90 at nadir in meters]
    5
  • 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).
  • Revisit time for defined data products
    1
  • More information and distinguishable features
    DigitalGlobe owns and operates the most agile and sophisticated constellation of high-resolution commercial earth imaging satellites. WorldView-1, GeoEye-1, WorldView-2, WorldView-3 and WorldView-4 together are capable of collecting over one billion square kilometers of quality imagery per year and offering intraday revisits around the globe.
