Riga, Latvia

January 17, 2006
This multitemporal color composite radar image is centered over Riga, the capital city of Latvia. The capital, which appears as a large bright area in the center of the image is the cultural and industrial center, and is also the major seaport on the River Daugava. The image shows that Latvia consists for the most part of a low-lying plain with some moderate elevations to the east. The landscape includes numerous lakes, streams, marshes, and peat bogs. The Daugava is the principal river, which rises in Russia and empties into the Gulf of Riga, where ice can be detected as dark green patches. The bottom portion of the image shows the northern region of Lithuania. The image was made using three ASAR Wide Swath radar images acquired on different dates and assigning a color (RGB) to each date (Red: 27 November 2002, Green: 16 April 2003, Blue: 5 February 2003).
