Barcelona, Spain

Barcelona, Spain

Published February 19, 2007

Barcelona, Spain, occupies a low plateau along the Mediterranean coastal plain. The city is the second largest in Spain (after the capital, Madrid), and it hosts the country’s largest seaport, portions of which are visible in the lower right of the image. This detailed astronaut photograph captures several notable features of the Barcelona urban landscape. The architectural design of the Eixample district (image center) displays a grid pattern distinctive for Barcelona. Built during the 19^th and 20^th centuries, the district was built with octagonal city blocks—rectangular blocks with the corners cut off. (At the level of detail of this photograph, the blocks appear to be squares.) The original intention was for buildings to occupy only two or three sides of the octagonal blocks, surrounding gardens and open space. While the original street grid pattern remains, today many of the octagonal blocks are completely built up.

Lake Khanka in Eastern Russia and China

Published February 18, 2007

At the juncture of the border between China and Russia sits Lake Khanka, also known as Lake Xinghai. Due to their importance to plant and animal species, the lake and the surrounding wetlands are protected by the Ramsar Convention, an international treaty for the protection and sustainable use of wetlands. Migratory birds that frequent this lake include several endangered species, such as the Japanese crane.
