NASA7-709-078 Adelaide Area, South Australia, Australia Winter/Spring 1998 Australia's fifth largest city, Adelaide, is visible slightly below the center of the image. Adelaide is the capital of South Australia and has a metropolitan population that exceeds one million people. The Port of Adelaide, located northwest of the capital, has a sheltered harbor that has been created by the large sand spit that juts northward along the eastern shoreline of the Gulf of St. Vincent. A hilly region, known as the Adelaide Hills, and low Mount Lofty Ranges (darker northeast-southwest aligned corridor) border the eastern edge of Adelaide. The hilly region northeast of Adelaide is noted for the vineyards that produce excellent wines. An extensive landscape of flat, fertile plains are located north of the urban area. Cultivated fields are identified as a network of angular-looking patterns. Linear-looking sandy beaches (lighter colored terrain) are visible along the coastline north of Adelaide.
