Imagery Sources
GeoEye set geospatial industry standards with the launch of IKONOS®,
the world's first 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.
IKONOS
Setting
the Standard
GeoEye first made history with the IKONOS satellite launch almost ten years ago.
IKONOS, derived from the Greek word for image, is the world's first commercial satellite
able to collect black-and-white (panchromatic) images with 1-meter 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.

GeoEye-1
GeoEye
will again make history with the upcoming launch of GeoEye-1—the world's highest
resolution commercial earth-imaging satellite.
GeoEye-1 will be equipped with the most sophisticated technology ever used in a
commercial satellite system. It will offer 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 will further expand applications for
satellite imagery in every commercial and government market sector. To learn more

OrbView-2
GeoEye’s
OrbView-2 collects on a daily basis color imagery of the Earth’s land and ocean
surfaces. As the foundation upon which GeoEye built the SeaStarSM
Fisheries Information Service, OrbView-2 provides imagery for maps used by commercial
vessels to detect favorable oceanographic fishing conditions. The satellite also
provides broad-area coverage in 2,800 km-wide swaths, which are routinely used in
naval operations, environmental monitoring, and global crop-assessment applications.
