1. ## [CWBP2] World Map construction thread

Since the project seems to have ground to a halt, and since I'm interested in seeing it continue (hopefully I'm not the only one) I have a new approach:

Our first step here is to make the world map.

Here is the continent mask I suggest we use:

This was constructed from pieces of the previous submitted maps from every author, they have been manipulated pretty heavily I suppose, but still they are there. I used my proposal map as a basis for it's construction keeping the elements of the overall world that I liked.

So first things first let us first discuss and address any problems seen with this map. After that I suggest we figure out the tectonics and lay in the mountain ranges, then after running it through Wilbur a couple of erosions cycles, we can work our the climate. Once that is all done we shall have our world map and we can move forwards.

Note: I measured the pixels with a proportionally representative projection and it works out to about 70% water, but I may have done it wrong. To me it seems ideal.

2. Those are continents at each pole? Assuming equirectangular as your projection, the poles appear as shown below:

Can I get any information on how you wrapped the continents around the globes for that image?

In WIlbur you can go from any projection to any other projection.
So you simply go from equirectangular (used here) to orthographic (showing a sphere) and then choose center of projection 90,0 (North pole) or -90,0 (South pole).

5. I've just found another mapping trope.
I was thinking that it looked wrong until I got it upside down. It look much better in my opinion probably because we are so used to have the landmasses in the north. It's arbitrary but it's the same thing here : http://blog.lib.umn.edu/globerem/main/Publication2.jpg

The map could look better (but become less practical for reasons mentioned a long time ago) by using a different projection. (I like mollweide) This is especially true for the poles. They are really distorted.

Is linking the continent (or one of them) to the pole another trope ? I saw this in a couple of maps including one made by -Max- (probably a commission). I would prefer to have an ice bridge. If there is sufficient ice in the north, this is easy to achieve. With some islands, the ice get trapped, does not flow south and take longer to melt. It's just an idea.

I have no problem reworking the tectonics of my continent (the biggest blob) it was too simplistic anyway.

If it's possible it would be nice to also include some part of Thurlor second map.

6. waldonrate: Yeah a continent at each pole, it just seemed interesting to me is the only reason. Part of this is that I wanted to include a "lake" there in the Southern pole. My thinking is that it will actually be a lower than sea level basin due to sublimation and lack of any input of new water and just be an interesting feature with good story possibilities. Perhaps I'm wrong, though, snow melt in summer could fill it I suppose, not really too sure on the scientific aspect TBH.

Azelor: The only reason it's in equirectangular is because that's the input of the NASA Map Projector thing. I think it's easier to conceptualize and work with also. For the final presentation I think we should use an expanding grid, and split the poles off and grid them separately.

Personally one of the reasons I liked the concept was because it was South heavy but we can flip it around, it's not important to me. I'm still thinking of it in terms of Northern culture dominating so it's somewhat challenging even in this state. It just strikes me as a good way to counter our own preconceptions for creative possibilities.

As for the land bridge to the Southern pole it is largely superfluous due to the likelihood of ice forming, but I figured the North sea had the ice possibility for a bridge and was just interested in a narrative sense of having a pole connected by land to the mainland. We can eliminate it if you want, but I feel like it has some good story potential there.

(It was actually Thulor's second map which I ended up using, it forms those four big islands just off the South pole. I haven't however used any elements of his first map because I couldn't think of what to do with them, but now I'm thinking we can use them for inland lakes or seas or something of that nature.
I used your northern island continent just above the big one and when I was editing it melded with that southern portion of one of my islands very well so I left it and it got kind of mangled too )

This is the map with proposed changes:

7. Interesting. Ice is likely to persist at the poles if there's something to attach to (even if there's not if it's cold enough). Antarctica has an ice cap about 2 miles thick, despite receiving effectively zero precipitation. Wikipedia suggests that the buildup at the actual pole is due largely to blown-in snow due to high winds.

My interest in the polar regions was mostly due to the continents being almost exactly centered on the poles. If that's land + ice, then it makes sense.

Here's a Wagner VII (equal-area) projection with a couple of stereographic endcaps.

8. Ah I understand, yeah I see your point, I hadn't even considered that, so no I cant say I was thinking of ice . Part of the problem is that while editing them I couldn't think of a way to work on the world 'endcaps' in a reasonable way and then try and stretch them out like that. I'm doing this all in GIMP so far.

9. I figured it was likely a practical implementation detail rather than a design one.

10. I prefer the original map orientation with the south-heavy landmasses. Just looks more aestethically pleasing to me.

As for the poles, one of the polar islands looks really tiny now. My suggestion is to either remove it or make it bigger (very easy to do, just move the coastline some distance away from the map's edge and whitefill the empty space). I don't really care whether either of them is connected to one of the continents.
