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
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. To learn more about GeoEye’s collection
and delivery capabilities, please visit our launch site.

IKONOS
Setting
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.
