cool!! this is an awesome alt map...

I think it's upside-down in the picture...

Very cool Selden.

This could make the start of a new education pack for Frank on the history of comparative planetology...

Malenfant,

Maps drawn by hand are usually made while observing through an inverting telescope, which shows South at the top. So the lettering is upside down if you have North at the top. The circular blotch at the lower right in the Celestia snapshot is Solis Lacus, in the southern hemisphere, with Noctis Labyrinthus to the north, just above it.

Hi Selden, it seems more detailled than the ancient one (by Robert Wills, IIRC)... BTW, it is a good companion of the Percival Lowell's map you ever provided
I'll add this ref in my catalog, nice work, thanks. Jeam

PS: Selden, it seems to me there are some tiny bugs in your pack:
1/ 'Lowell's canals: colored' is quoted twice in the .ssc file
2/ 'plmars-texture-1k' isn't quoted in the .ssc file (but .jpg file with this name is present in the textures/medres folder.)
3/ About Mineralogy: the 1k textures you show in the site page are not compiled in the pack ('tes-[mineral]-1k.jpg' files)
Personnaly, I added them in my own pack (as usual, I re-compile the add-on with French explanations/texts)...

If it can help, Jeam

OK... but I notice that the area labelled as Tharsis is somewhat offset from where it should be (ie where the volcanoes are). And wouldn't he have labelled Olympus Mons somehow too?

i agree it's a little less accurate than I would have expected. But remember, this is one of the very first attempts to map another planet.

Jeam,

Thanks for pointing out the problems. I'll try to fix them in a few days.

From someone who does public outreach and educationsl activities with the instrument used by Schiaparelli for doing that map: cool
