The northern end of the island country of Taiwan, including the capital city of Taipei, is shown in this spaceborne radar image from NASA's Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar. Taipei is the bright blue and red area.

The northern end of the island country of Taiwan, including the capital city of Taipei, is shown in this spaceborne radar image. Taipei is the bright blue and red area in the lower center of the image. A portion of the city sits on an island surrounded by the Keelung and Freshwater Rivers. The main channel of the Freshwater River is to the right of the island and appears dark in the image. The channel to the left of the island is no longer active and appear slighter. Rugged, heavily vegetated mountains surround the city and are shown in green. The runways of the Chiang Kai Shek International Airport are seen as dark parallel strips in the upper left of the image.

This image was acquired by Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the space shuttle Endeavour on April 10, 1994. The image is 50 kilometers by 33 kilometers (31 miles by 20 miles) and is centered at 25.1 degrees north latitude, 121.5 degrees east longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations of the radar as follows: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted, vertically received; and blue is C-band, horizontally transmitted, vertically received. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Mission to Planet Earth program.
