ISS014-E-15258 (26 Feb. 2007) --- Kwangju, South Korea is featured in this image photographed by an Expedition 14 crewmember on the International Space Station. The Metropolitan City of Kwangju (or Gwangju) is the fifth largest urban area in South Korea with a population of 1.4 million people. It is a major economic and cultural center for the southern portion of the country, located in a geographic basin with high mountains to the east (the mountain of Mudeungsan to the east has a peak elevation of 1,140 meters) and more open plains to the west. The city is perhaps best known to the West as the location of the Gwangju Massacre in May 1980, during which civilian demonstrators were killed by government forces. This event has led to identification of the city within South Korea as "the shrine of Korean democracy." The most notable feature in this view is an interesting blue cast to the urbanized regions. Digital photographs capture the same red, green, and blue wavelengths of reflected light that human eyes are sensitive to (known as a "true-color" image), and urban areas typically appear in tones of grey. The distinctive blue-grey color of the Kwangju metropolitan area is the result of numerous blue building rooftops, present on both small residential buildings and large industrial buildings such as those located at center and right.




Kwangju, South Korea:

Kwangju (or Gwangju) Metropolitan City is the fifth largest urban area in South Korea. With a population of 1.4 million people, it is a major economic and cultural center for the southern portion of the country. The city is located in a geographic basin with high mountains to the east—the mountain of Mudeungsan has a peak elevation of 1,140 meters (3,740 feet)—and more open plains to the west.

The most notable feature in this astronaut photograph is an interesting blue cast to the urbanized regions. Digital astronaut photographs capture the same red, green, and blue wavelengths of reflected light that human eyes are sensitive to (known as a “true-color” image), and urban areas typically appear in tones of grey in such images. The distinctive blue-grey color of the Kwangju metropolitan area is the result of numerous blue rooftops, present on both small residential buildings (not visible at the image resolution) and large industrial buildings such as those located at image center and image right. High-resolution imagery of the rooftops (not shown) suggests that the blue color is the result of painting rather than an intrinsic characteristic of the building material.

Gwangju is perhaps best known to the West as the location of the Gwangju Massacre of May 1980, in which civilian demonstrators were killed by government forces during a period of military rule in South Korea. The event is commonly described as the driving force behind the country’s democratic reforms, and it has led to identification of the city within South Korea as “the shrine of Korean democracy.”
