After some tinkering with 2 images of Janus, I have re-projected and worked on a accurate map for the moon.
The only other surface map i know of is http://www.johnstonsarchive.net/spaceart/cmaps/janusmap.jpg , but its super low resolution. there was a another image of Janus i wanted to compile in there but i couldn't seem to find the view in relation to a 3d model so i can find the pole of the moon for re-projection and it does line up correctly to the model in Celestia hope you enjoy this new map (there may still be some minor alignment issues) |

Unfortunately, Janus was poorly covered by Cassini, when compared to the excellent coverage of its partner Epimetheus. Beyond the images released in the Photojournal, a quick search of OPUS reveals a few more opportunities that could be added to the map:
https://opus.pds-rings.seti.org/opus/#/inst...s=1&detail= Unfortunately a lot of the better quality images were taken at higher-phase angles, but maybe there are a few that can expand coverage. Thanks TrappistPlanets for giving this a try. Would be good to see more Cassini-based shape models and maps of the minor moons become available. -------------------- &@^^!% Jim!
