Hubble Space Telescope map of Titan's surface
The latitude ranges from 60 deg South to 60 deg North, the
longitude from 0 to 360 (E longitude increasing to the right, following the
geographical--as opposed to astronomical--convention),
with 180 in the center. The grid is
30 deg in latitude and in longitude. The sub-Saturn point
is at 0 E, 0 N, and the sub-Earth latitude is 7 N. The contour lines are at
2% intervals. Want to see the

red borders were not imaged.
This map was made from the 7 F673N images of Titan, which
are sensitive to red light. At
the beginning of our obsering period, the sub-Earth longitude was
about 240 E. The images were taken approximately
every seven hours.
During the time
these images were taken,
the large bright feature slowly moved off of the observable disk.
In themselves, the images do not reliably demonstrate surface features.
However, the bright region in the F673N map appears to be the same as
that visible in the longer wavelength maps. Much of what you see is noise;
the light from the surface has almost certainly been scattered
once or twice on its way out of the haze. This wavelength is longer than
those used by the Voyager cameras, but the contrast is still small (~1%).
