Sudan, Africa as seen from STS-66 shuttle Atlantis

Agricultural patterns are distinctly visible in this near-vertical false color infrared photography taken in November 1994. The area depicted on the photograph is south of Khartoum between the White and Blue Nile Rivers. By far the most important irrigation project in sub-Saharan Africa, both large and small scale agricultural enterprises have been developed using water transported from the perennial Nile Rivers. Hundreds of small rectangular fields and water-filled canals can be seen in this photograph.
