Product Specifications
Geo, GeoProfessional and GeoStereo imagery products are classified according their
resolution and positional accuracy, e.g., an object's location in relation to its
true position on the Earth's surface. GeoEye is pleased to offer our customers a
variety of ways to meet their unique imagery requirements. Please contact
GeoEye Customer Service if you have questions related to our imagery products,
these specifications, or if you would like to review your needs with a GeoEye imagery
professional.

Geolocation Accuracy for GeoEye-1
The observed accuracy performance for GeoEye-1 is consistently better than the 5m CE90* specification based on rigorous assessment studies. In 2010 the CE90 for mono collections was 3.8m and the CE90 for stereo collections 3.5m. Details on Geolocation Accuracy Test Results can be found in the JACIE 2011 presentation, "GeoEye-1 Geolocation Assessment and Reporting Update."

Note : Location error is defined in relation to a confidence level (i.e., range of error)
of 90% (CE90)—meaning that the object's location is represented on the image, within
the stated accuracy, 90% of the time. The CE90 accuracy scale can be related to
Root Mean Square Error (RMSE) as well as the U.S. National Map Accuracy Standards
(NMAS).
