False-colour satellite image of sand dunes in the Rub al Khali - the "Empty Quarter",one of the World's most extreme deserts. Located between Oman and South Yemen to the south and southern Saudi Arabia to the north,the Rub al Khali occupies a region measuring 1300km by 500km. This desert supports few plants or animals and no permanent human settlements; its major features are long ridges of dry wind-blown sand (sief dunes,yellow). Futher to the east (right),the formations change to a star-dune pattern. The blue areas represent wetter,more low-lying sand. The image was recorded by the Landsat earth resources mapping satellite | |
