Titan's Unnamed Methane Sea - With Fixed Lat / Lon

Titan's Unnamed Methane Sea

Titan's Unnamed Methane Sea

Got to go to my grandson's baseball game. Will explain this when I get back. The map's lat/lon is corrected based upon feedback.

Okay, I'm back. The game was fun, I shopped for vinyl records and am ripping a copy of the soundtrack for the movie The Commitments (great soul music). Now I can explain my fixed map. Jason Perry, of the Cassini Imaging Team and a Titan map maker posted the following comment to my original post explaining lat/lon on this extraterrestrial body:

O° West is straight down. For worlds like Titan, longitude is defined as degrees west from the average Sub-Saturn point. In the map you show, 0° West is straight down, and longitude increases to 360 W in the clockwise direction.

Keep in mind that the sea you mapped is the smaller of the two main northern seas. The one to the west, seen in the radar image in two places: the northern part of the sea with the large island in the middle, and part of the middle of the sea to the lower right in PIA10008 as posted here.

As a result, I adjusted the longitudes by adding 180° to each of my original longitudinal lines.

Enjoy!
