Topographical map of the Ice bed of Antarctica
Over at the Facebook group there was a short discussion about a topographical map of Antarctica without snow and ice.
So, why not give it a try in CC3+?

Looking at these maps make me want to have more adventures for my players in the polar regions. And by coincidence, they did visit the north pole during last session. My world don't have landmasses in the poler regions though, only thick ice sheets.
Remy - maybe its time to invent a global catastrophe that causes the rise of at least one polar landmass?
The map(s) shown here are from the BEDMAP 2 survey project conducted by the British Antarctic Survey in recent years (you can access a much enlarged version of of the first map shown by WeathermanSweden on the linked page). It's also worth reviewing at least the first map (Fig 1) in a paper available for free PDF download via ResearchGate The glacial geomorphology of the Antarctic ice-sheet bed, because this shows both the current coastline (black outline) and the rebounded one Loopysue was talking about (white outline). The latter confirms Antarctica sans ice would indeed be a substantial "new" solid landmass to explore, along with some significant islands of many sizes across much of what's now called West Antarctica.
A similar one can be archived by adding one third of the ice thickness to the heights of the Antarctic ice-sheet bed to simulate land raise after the ice has gone.
Not that this method is quite scientific...but the the result is quite similar...
In this map you also see the boundaries of the dataset I used (Wyvern mentioned it above)
So this is how Antarctica approximately could have looked like before the ice came(or what it may look like a "long time" after when all ice is gone)...
Maybe worth adding the FCW file for this version of Antarctica too, if you're willing?
If anyone wants to play around a little more with the appearance of Antarctica, albeit not at this level of top-down completeness, it's worth seeing the NASA website for details from the IceBridge Mission, one of the contributors of data to the BEDMAP 2 project.
This page is the most recent news item, posted at the Mission's conclusion in December 2019, but this one is more fun, because it lets you slide the ice across or away from the whole imaged topographic view! There's quite a bit of vertical exaggeration to get the surface features to show up properly at this continental scale, but that helps it look more like some of the usual CC3+ overland mapping styles to me. Plus there's an image further down that second linked page where you can do a similar sliding comparison between the original, less detailed, BEDMAP survey and the newer BEDMAP 2 one.
We got a fantasy world - based on real world data with some adjustments...

Is it only me, or does your map just scream for a whole new fantasy novel?
Or at least an intricate fantasy map?
I'm just doing a "Loopysue-fantasy-terrain-terraforming" with it
So let's wait and see how it looks like with rivers... ...when iceless Antarctica has gone through your Annual
Just now I have completed the Wilbur-cycle and the land is back in FT3 - where it now generates the rivers...my pc is cooking...55%...

I was curious about that myself, but I thought about the fact that the mountain tips were already eroded and didn't want to suggest it in case it just looked weird. But if you're doing it anyway...
Some of those glacial valleys are simply vast.
But now it definitely looks worth a novel or two.
When you say "with shading effects", is that still the CC3 map?
And yes, Sue - "The shading-effects-map" is a CC3+ - map; actually the same as above, but with a lightmap-image from Wilbur imported to a separate sheet that is blended to the colour contour sheet.
It is some kind of a temporary solution; still trying to find other ways to do it.
I can post a link to the FCW and the lightmaps if you like.

I imagine that I would not be the only one who would much enjoy being able to view this at leisure on my screen - thank you very much

Without Sheet-effects you should get the above version without shading.
With effects on you get this one.
If you want the darker version above, change the blender mode effect in the CONTOURS (LAND) sheet from "Hard Light" to "Multiply".
Greetings,
André
I love your colour styles from Sue's November Annual - so just by a few clicks and changing the colour palette of the map we can create winter conditions...
