Myanmar - October 23rd, 2011

Clouds hang over the tops of the mountainous terrain of southwest China, near the border with Myanmar (left). Many of these mountain ridges are in the province of Yunnan, a series of high mountain chains spreads across the province, especially in the north and west.

Visible to the south is the sediment-laden Gulf of Martaban, an arm of the Andaman Sea in the southern part of Myanmar. The Salween Sittaung and Yangon rivers empty into it. A characteristic feature of the Gulf of Martaban is that it has a tide-dominated coastline. Tides ranges between 4–7 m with the highest tidal range at the Elephant Point in the western Gulf of Martaban.

China - May 18th, 2011

This image stretches across Yunnan Province, China. The terrain is largely mountainous, especially in the north and west – a series of high mountain chains spreads across the province. Yunnan’s major rivers flow through the deep valleys between the mountains.

Several lakes are visible on the right side of the image. The dark blue body of water with the slightly uneven hourglass shape is Fuxian Lake. It has a surface area of 212 square kilometers and a maximum depth of 155 meters.

Northwest of Fuxian Lake is the greenish Lake Dian or Kunming Lake, a large inter-land lake located on the Yunnan-Guizhou Plateau. The lake covers 298 km2 and has an average depth of 4.4 m.

In the center of the image is Er Lake, an alpine fault lake with an area of 250 km² and an average depth of 11 m. The lake is situated by the Cangshan Mountains (to the west).

This orthorectified image shows Mengzi County, in the southeast of Yunnan, China, in the Honghe prefecture about 12 miles east of Gejiu. The Datunhai (left) and Changqiao Hai (right) lakes can be seen nearby.

Mengzi County is situated in the center of a fertile valley basin on a plateau 1000 meters above sea level. Most of the rest of Yunnan, however, is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. In the west, the relative height from mountain peaks to river valleys can be as much as 3,000 m.

Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the relative height from mountain peaks to river valleys can be as much as 3,000 m. Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has over 17,000.

Yunnan’s reserves of aluminium, lead, zinc and tin are the largest in China, and there are also major reserves of copper and nickel. Yunnan has over 600 rivers and lakes, which provide an annual water supply of 222 billion cubic meters. Projected hydropower reserves stand at 103 GW, with an exploitable capacity of 90 GW.

Smoke in Valley in Southwest China

China and Myanmar - December 19th, 2010

The mountainous area in the center of this image marks the border between Myanmar (lower left) and China (above and right). Smoke can be seen filling a valley on the right side of the image, by the border of China’s Yunnan province.

The province is located in the far southwest of the country and situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast.

In the west, the relative height from mountain peaks to river valleys can be as much as 3,000 m. This explains the containment of the smoke in the valley – it is unable to spread beyond the high surrounding mountains.

China - November 9th, 2010

Smoke hangs in the air over the Sichuan Basin in the Chinese province of Sichuan. Tall mountains, capped in snow in this image, are holding the smoke within the low-lying basin.

The area of the Sichuan Basin is bordered by the Himalayas to the far west, including the nearby Tibetan Plateau, the Qinling range to the northeast, and mountainous areas of Yunnan to the south.
