The GeoEye-1 satellite collected this .50-meter resolution image of Khalifa
Sports City in Doha, Qatar on January 10, 2009, and
serves as an example of the resolution, clarity, and color
quality being produced by GeoEye-1. The image was
taken from 423 miles in space as GeoEye-1 moved from
north to south over the Middle East at 17,000 mph. It
shows the blue-domed Hamad Aquatic Centre in Doha,
Qatar’s capital and largest city. GeoEye-1 is the world’s
most advanced commercial imaging system with the
highest-resolution imaging capabilities and geolocation
technologies. It simultaneously acquires 0.41-meter panchromatic
and 1.65-meter multispectral images, which
are merged to create .50-meter color (pansharpened)
imagery products. (Due to U.S. Government licensing,
commercial customers receive .50-meter color imagery).
GeoEye’s products and services enable timely, accurate,
and accessible location intelligence. Headquarted in
Dulles, Virginia, GeoEye is recognized as one of the
geospatial industry’s most trusted imagery experts, delivering
reliable service and exceptional quality imagery
products and solutions to customers around the world.
GeoEye’s products serve applications including defense
and intelligence, precision mapping, online mapping,
infrastructure development, planning and monitoring, and environmental assessment. For more information
