Home to more than four million people from over 100 countries, Sydney is the largest and most cosmopolitan of Australia's cities. This simulated true-color Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image shows the Sydney metropolitan area on October 12, 2001, and covers an area of 42 by 33 kilometers. The image displays the concentrated development of the urban area. Sustainable use of water and effective water management are prime concerns for the area. The city has developed numerous dams and water storage areas, including the Prospect Reservoir, located at the upper left edge of the image. Built in 1888, this reservoir is one of Sydney's oldest and was once the major water storage facility for the city.
