Dublin, Ireland
Photo ID:P-46297
October 19, 1995
This radar image of Dublin, Ireland, shows how the radar
distingishes between densely populated urban areas and nearby
areas that are relatively unsettled. In the center of the image
is the city's natural harbor along the Irish Sea. The pinkish
areas in the center are the densely populated parts of the city
and the blue/green areas are the suburbs. The two ends of the
Dublin Bay are Howth Point, the circular peninsula near the upper
right side of the image, and Dun Laoghaire, the point to the
south. The small island just north of Howth is called "IRELAND'S
EYE," and the larger island, near the upper right corner of the
image is Lambay Island. The yellow/green mountains in the lower
left of the image (south) are the Wicklow Mountains. The large
lake in the lower left, nestled within these mountains, is the
Poulaphouca Reservoir along River Liffey. The River Liffey, the
River Dodden and the Tolka River are the three rivers that flow
into Dublin. The straight features west of the city are the
Grand Canal and the three rivers are the faint lines above and
below these structures. The dark X-shaped feature just to the
north of the city is the Dublin International Airport. The image
was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic
Aperture (SIR-C/X-SAR) when it flew aboard the space shuttle
Endeavour on April 11, 1994. This area is centered at 53.3
degrees north latitude, 6.2 degrees west longitude. The area
shown is approximately 55 kilometers by 42 kilometers (34 miles
by 26 miles). The colors are assigned to different frequencies
and polarizations of the radar as follows: Red is L-band
horizontally transmitted, horizontally received; green is L-band
vertically transmitted, vertically received; and blue is C-band
vertically transmitted, vertically received. SIR-C/X-SAR, a
joint mission of the German, Italian, and the United States space
agencies, is part of NASA's Mission to Planet Earth.
