Imaging & Collection Specifications

Launch Date September 6, 2008
Camera Modes
  • Simultaneous panchromatic and multispectral (pan-sharpened)
  • Panchromatic only
  • Multispectral only

 
Resolution 0.41 m / 1.34 ft* panchromatic (nominal at Nadir)
1.65 m / 5.41 ft* multispectral (nominal at Nadir)
Metric Accuracy/Geolocation Mono: 5 m CE90, horizontal, without GCP, exclusive of terrain displacement
Stereo: 4 m CE90, horizontal, without GCP
6 m LE90, vertical, without GCP
These are specified as 90% CE (circular error) for the horizontal and 90% LE (linear error) for the vertical with no GCP (ground control point)

Daily Monoscopic Area
Collection Capacity		 Up to 700,000 sq km/day (270,271 sq mi/day) of pan area (about the size of Texas)
Up to 350,000 sq km/day (135,135 sq mi/day) of pan-sharpened multispectral area  (about the size of New Mexico)

* Data reflects ground sample distance resolution at Nadir for exclusive use by the U.S. government and any foreign government that the U.S. government may designate. Imagery sold to commercial customers will be resampled to 0.5-meter resolution. GeoEye’s current operating license with NOAA does not permit the commercial sale of imagery below 0.5-meter resolution.
