South Korea

On December 9, 2020, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image of the rugged, green landscape of South Korea.

Sitting at the southern end of the long Korean Peninsula, South Korea’s extensive coastline measures about 2,413 kilometers (1,332 mi) long and stretches along the Yellow Sea (west), Cheju Strait (southwest), Korea Strait (southeast) and the Sea of Japan (East Sea). In the north, South Korea shares a 237 km (147 mi) land border with North Korea.

With an area of 96,920 sq km (37,421 sq mi), South Korea measures a little smaller than the U.S. state of Pennsylvania and a little larger than Indiana. Mountains make up about 70 percent of the country. The Taebaek Mountains form a forested and rugged spine along the eastern coast of the Peninsula, extending into North Korea. In the south, the Sobaek Mountains dominate. As mountains give way to the surrounding seas the landscape expands into lowlands and coastal plains. Numerous islands sit off the western and southern coasts.

South Korea's population is concentrated primarily in lowland areas, creating numerous high-density cities. The largest of these is Seoul, the political and economic heart of the country, which sits in the northwest corner roughly 30 miles south of North Korea. This is where slightly less than half of the population of the entire country resides. In the upper right section of this image, Seoul can be seen as a large cluster of light gray pixels clustered around the dark waters of the Han River, which runs through the center of the city.
