Imagery Sources

GeoEye set geospatial industry standards with the launch of IKONOS®, the world's first sub-meter commercial satellite. Driven to continue this trend through an intense commitment to our clients, we own and operate an extensive constellation of Earth-imaging satellites, mapping aircraft and an international network of ground stations. These resources, coupled with our vast imagery archive and advanced imagery-processing capabilities, allow us to offer a broad spectrum of imagery products that our clients continue to rely on year after year.


GeoEye-1

GeoEye Image Source - facegis.comGeoEye again made history with the Sept. 6, 2008 launch of GeoEye-1—the world's highest resolution commercial earth-imaging satellite.

GeoEye-1 is equipped with the most sophisticated technology ever used in a commercial satellite system. It offers unprecedented spatial resolution by simultaneously acquiring 0.41-meter panchromatic and 1.65-meter multispectral imagery. The detail and geospatial accuracy of GeoEye-1 imagery further expands applications for satellite imagery in every commercial and government market sector.

IKONOS

GeoEye Image Source - facegis.comSetting the Standard

GeoEye first made history with the IKONOS satellite launch on Sept. 24, 1999. IKONOS, derived from the Greek word for image, is the world's first commercial satellite able to collect black-and-white (panchromatic) images with 82-centimeter resolution and multispectral imagery with 4-meter resolution. Imagery from both sensors can be merged to create 1-meter color imagery (pan-sharpened). The more than 300 million square kilometers of imagery that IKONOS has collected over every continent is being used for national security, military mapping, air and marine transportation, and by regional and local governments.
