I've been processing some of the high resolution Galileo Ganymede images recently. As far as I know the two mosaics below have not appeared at the official websites (at least not in this form) so in a sense they are 'new'.
The first one was obtained during the G1 flyby in 1996. It covers a part of Memphis Facula which is centered at roughly 15°N, 132°W. The images were obtained at a distance of approximately 5000 km from Ganymede's center. The second one was obtained during the G28 flyby in May 2000. It is centered near 14.5°S, 319.7°W. The images making up the mosaic were obtained at a distance of roughly 4500 km from Ganymede's center. I will probably post more Ganymede mosaics later this month or next month. |

Great mosaic, especially when keeping in mind that it was made more than 10 years ago. Reminds me of when I made my first 'real' (and big) planetary map towards the end of the 20th century - it was of Ganymede. My computer was completely swamped, a lot of time was spent on calculation runs and it crashed several times. Now I could make a *much* bigger map with ease and much more quickly.
Needless to say, seeing the scripts would be interesting. There are some ISIS users here. |

Funnily enough, I still have some email correspondence with you about making those maps . |
