The National Geospatial Intelligence Agency (NGA) has contracted the use of DigitalGlobe data for the US federal government. Data from multiple DigitalGlobe satellites (including data from multiple DigitalGlobe satellites: IKONOS, GeoEye-1, QuickBird, WorldView-1, -2, and -3) are available in the science cloud. Most of the DigitalGlobe imagery on the ASC is Basic (1B) imagery which has not been orthorectified or converted to reflectance. For more information on how to do this, see the “ASC How To” documents.
