Haiti and Caribbean Neighbors - September 30th, 2009

Haiti and Caribbean Neighbors - September 30th, 2009

Several Caribbean islands and nations can be seen here, including Haiti and parts of the Dominican Republic (right), Cuba (center left), Jamaica (lower left), some islands of the Bahamas (north and northeast of Cuba) and the Turks and Caicos Islands (north of Haiti).

Of note is the Cordillera Central range, the greatest of the Dominican Republic’s mountain chains, visible as a dark green area stretching from the Haiti-Dominican Republic border to the far right edge of the image. The Cordillera Central extends from the plains between San Cristóbal and Baní to the northwestern peninsula of Haiti, where it is known as Massif du Nord.

Pico Duarte, the highest peak in all of the Caribbean islands, can be found in the Cordillera Central. The mountain’s height continues to be debated; the official elevation as recorded by Dominican government agencies is 3,087 meters, while 2003 estimates using GPS technology have found it to be 3,098 meters.

Cape Fear River Spilling Sediments off North Carolina Coast, USA

USA - September 29th, 2009

The Cape Fear River is a 202 mile (325 km) long blackwater river in east central North Carolina in the United States. It flows into the Atlantic Ocean near Cape Fear, from which it takes its name. Here, greenish sediments flow from the rivermouth into the Atlantic.

The river has its source at Haywood, by the confluence of the Deep and Haw rivers just below Jordan Lake. It flows southeast, then receives the Black River approximately 10 miles (16 km) northwest of the city of Wilmington, which appears as a greyish-brown area north of the rivermouth.

At Wilmington, it receives the Northeast Cape Fear River and turns south, widening as an estuary and entering the Atlantic approximately 3 miles (5 km) west of Cape Fear.

Another body of water visible west of the estuary is Lake Waccamaw, an oval-shaped freshwater lake measuring roughly 5 miles by 7 miles with an average depth of 7.5 feet.

France, Switzerland, Italy - September 29th, 2009

Three mountain ranges can be observed in this image focusing on France, Switzerland and northwestern Italy: the Pyrenees, the Massif Central and the Alps. The peaks of the Massif Central are generally lower than those of the other two ranges.

The Pyrenees (bottom left) provide the border between Spain and France. Their highest peak is  Pico d’Aneto or Pic de Néthou, at 3,404 metres (11,168 ft) in the Maladeta Ridge.

The Massif Central is located in south-central France. The tallest peak is Puy de Sancy, 1886 meters high, in the Monts-Dores Range.

Finally, the Alps stretch from France in the west through Italy, Switzerland, Liechtenstein and Germany, to Austria and Slovenia in the east. The highest mountain in the Alps is Mont Blanc, at 4,808 metres (15,774 ft), on the Italian–French border.

Beijing, China - September 24th, 2009

Beijing, a metropolis in northern China and the capital of the People’s Republic of China, appears as a glittering white expanse in this orthorectified image. The city is situated at the northern tip of the roughly triangular North China Plain, which opens to the south and east of the city.

Mountains to the north, northwest and west shield the city and northern China’s agricultural heartland from the encroaching desert steppes. The northwestern part of the municipality, especially Yanqing County and Huairou District, are dominated by the Jundu Mountains, while the western part of the municipality is framed by the Xishan Mountains.

Major rivers flowing through the municipality include the Yongding River (west of the city) and the Chaobai River (east of the city), part of the Hai River system, which flow in a southerly direction. Miyun Reservoir, built on the upper reaches of the Chaobai River, is Beijing’s largest reservoir, and crucial to its water supply.
