Argentina - October 6th, 2009

Tierra del Fuego (Spanish for “Land of Fire”) is an archipelago 73,753 km2 (28,476 sq mi) off the southernmost tip of the South American mainland, across the Strait of Magellan. The southern point of the archipelago forms Cape Horn.

Tierra del Fuego is shared by Argentina and Chile. More precisely, 18.507,3 km2 belongs to Argentina (38,57% of the region’s total surface), 29.484,7 km2 belongs to Chile (61,43% of total surface).

The climate in this region is very inhospitable. It is a subpolar oceanic climate (Köppen climate classification Cfc) with short, cool summers and long, wet, moderate winters. The precipitation averages 3,000 mm (118 in) a year.

Temperatures in Ushuaia hardly surpass 9 °C (50 °F) in summers and average 0 °C (30 °F) in winters. Snowfall can occur in summer. The cold and wet summers help preserve the ancient glaciers.

The southernmost islands possess subantarctic climate typical of tundra that makes the growth of trees impossible. Some areas in the interior have a polar climate.

Somalia and Ethiopia - November 16th, 2009

The Horn of Africa is the easternmost region in Africa, comprising the countries of Somalia, Ethiopia, Eritrea and Djibouti. This image includes most of Somalia and the eastern part of Ethiopia.

No distinct geographical feature clearly deliminates the border between the two countries in this image, although it is suggested by the more rusty colored Ethiopian land towards the center.

While Ethiopia is landlocked, Somalia has a long coastline of 3,025 kilometers that has been of importance for trade. Inland, Somalia’s terrain consists mainly of plateaus, plains, and highlands. However, there are some rugged mountain ranges in the north near the Gulf of Aden coast; these are the Karkaar Mountains, which appear dark green here.

While Ethiopia also has several important mountain ranges, the land area here is much lower and flatter than the western parts of the country.

Sri Lanka - November 12th, 2009

The island of Sri Lanka lies in the Indian Ocean, to the southwest of the Bay of Bengal and to the southeast of the Arabian Sea. It is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait.

The island consists mostly of flat-to-rolling coastal plains, with mountains rising only in the south-central part. This mountainous area of the country is depicted here in this orthorectified image. Amongst these is the highest point Pidurutalagala, reaching 2,524 metres (8,280 ft) above sea level.
