Very cool map, thanks for educating (me, at least), Phil!

"Fogland"...interesting. That wouldn't happen to coincide approximately with the Tharsis region, would it?

I like "windy land." Is that Hellas? Appropriate name for the source of planet-encircling dust storms

This original map is south up - mine was north up. So yes, Windy Land is Hellas, but Fog Land is Argyre, not Tharsis!

Phil

i have 12 maps

all south up , well the image in the scope is upside down without a Barlow lens .
the 3 oldest
the images are 2048x1024

i was having some fun with them years ago in Celestia back in `03

it is interesting how things have changed over the years . From Edgar Rice Burroughs to " it's like the moon" with Merrier
then to date with "hay there is melting water STILL " shots from mro and hirise

Here's another oldie but goldie:

The 1783 map by William Herschel, drawn in a south polar azimuthal projection, here reprojected into a cylindrical projection with north up. This was the first map of Mars ever compiled. It's often overlooked because of the unusual projection, but in cylindrical projection it's not bad at all. The big dark-ringed shape at the bottom is the residual south polar cap.

Phil I did not know of that one
from 1783 cool

Here are a couple of other early maps which I have converted to cylindrical projection for use elsewhere. The Beer and Madler map corrects a mistake in their original. The Green map adds the poles, and in both cases the original grid and text labels have been removed.

I've added an illustration showing five historic maps of Mars, including the three shown above, but all reprojected into a different projection, to my Mars Atlas web page:

This is from the historical intro part of the book.

Phil I really love the Lunar Book. I can't wait for this one.
