Malay Peninsula - January 6th, 2012

This wide-swath ASAR image shows the Malay Peninsula (or Thai-Malay Peninsula), a peninsula in Southeast Asia (visible in its entirety in the full image). The land mass runs approximately north-south and, at its terminus, is the southern-most point of the Asian mainland. The area contains the southernmost tip of Burma, Peninsular Malaysia, Singapore, and Southern Thailand.

The image shows the ridges and contours of the Titiwangsa Mountains, part of the Tenasserim Hills system, that form the backbone of the Peninsula. They form the southernmost section of the central cordillera which runs from Tibet through the Kra Isthmus (the Peninsula’s narrowest point) into the Malay peninsula.

Democratic Republic of the Congo and Rwanda - January 9th, 2012

This wide-swath ASAR image shows volcanic features around Lake Kivu, one of the African Great Lakes. It lies on the border between the Democratic Republic of the Congo and Rwanda, and is in the Albertine Rift, the western branch of the East African Rift.

Visible as a bright white area on the northern shores of the lake, are the cities of Goma, in the Democratic Republic of the Congo, and Gisenyi, in Rwandu. Goma lies only 18 km due south of the crater of the active Nyiragongo Volcano.

Mount Nyiragongo is a stratovolcano in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo. The main crater is about two km wide and usually contains a lava lake.

Wetlands and Tengiz Oil Field on Northeastern Shores of Caspian Sea

June 19th, 2012 Category: Lakes, Wetlands

Caspian Sea - January 5th, 2012

This wide-swath ASAR image shows the northern part of the Caspian Sea, in Kazakhstan. While the sea apears dark grey, the land actually extends out further into the dark grey area than the edge of the light grey area suggests. The medium grey zone between there and the shores of the sea is an area of low-lying wetlands. Located beneath these wetlands is the Tengiz field, an oil and gas field that covers a 2,500 km2 (970 sq mi) project license area. The reservoir is 19 km (12 mi) wide and 21 km (13 mi) long.

Jagged Contours of Lake Volta, Ghana

Ghana - January 3rd, 2012

This orthorectified wide-swath ASAR image shows the jagged contours of Lake Volta, the largest reservoir by surface area in the world, and the fourth largest one by water volume. It is located completely within the country of Ghana, and it has a surface area of about 8,502 km² (3,275 square miles). Lake Volta lies along the Greenwich Meridian, and just six degrees of latitude north of the Equator. The lake’s northmost point is close to the town of Yapei, and its southmost extreme is at the Akosombo Dam, 520 kilometers downstream from Yapei. The Akosombo Dam holds back both the White Volta River and the Black Volta River, which formerly converged, where the middle of the reservoir now lies, to form the single Volta River. The present Volta River flows from the outlets of the dam’s powerhouse and spillways to the Atlantic Ocean in southmost Ghana.
