Terrain seen here is on the Trailing Hemisphere of Titan, which is facing Saturn. This view is centered on 54° North Latitude and 251° West Longitude.
Titan's north pole lies on the Terminator, about one-third of the way inward from the top of the image.

The image was taken in Violet Light with the Cassini Spacecraft wide-angle camera on May 21, 2009. The view was obtained at a distance of approx. 147.000 Km (such as about 91.000 miles from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 121°.
Image scale is roughly 9 Km (a little les than 6 miles) per pixel".
