Beijing China
SAR Orbit number: 39150
16 October 2002
Description:
This Synthetic Aperture Radar (SAR) multitemporal colour composite image is centred
over the city of Beijing (bright area centre image), capital and largest city of China. The image
shows the urban area of Beijing spreading out in bands of concentric ring roads. Tian'anmen square
is right at the centre of Beijing, and is directly to the south of the Forbidden City and to the
east of Zhongnanhai. Running through central Beijing from east to west is the well known Chang'an
Avenue. The city capital's airport is visible as a black "H" figure northeast of the city. The
various colour patches dispersed throughout the image indicate cultivated agricultural fields.
The image is made of three ERS-2 SAR PRI (Precision Radar Image) images acquired on different dates
and assigning a colour (RGB) to each date of acquisition.
