North Korean World Map Found

[quadibloc]

I decided to search for "North Korean Atlas" instead of "North Korean World Map", and I turned up a result which finally let me see a genuine world map from North Korea:

However, all is not quite well. I can't identify the projection in order to draw a map on the same projection to include on my web site.
It looks a bit like either the Times Atlas projection or the Urmayev II (not the Urmayev II Cylindrical). There's also the Kavraisky VII and the Ginzburg VIII to consider as well. But it differs from most of these possibilities in that Africa and other places on the Equator aren't elongated vertically.
Incidentally, this has motivated me to redo and probably correct the diagrams of the Winkel Tripel projection that I had - and in addition to the original and Bartholomew's variant, I've now also added the Winkel Tripel BOPC of which I have just learned.

It really should not have surprised me that all the labels are in Korean, and therefore I can't read them.

Nice find. I did not compare in depth, but this is surely the 等差分纬线多圆锥投影 (Latitudinally equal-differential polyconic projection).

I’m a bit confused now – aren’t we talking about the World map image which of course is no polyconic projection?

Provided we do talk about the map I linked to above, it shows
– increased spacing of straight parallels towards the poles,
– probably equally spaced meridians along the equator (the distance doesn’t seem exactly the same everywhere, but this might be due to the poor accuracy of the drawing),
– non-elliptical curved meridians.

I don’t think I know a projection with this specific set of properties. (And if I do, I have forgotten about it for good reasons )

No, I’m a bit confused. When I wrote “I did not compare in depth”, I think I meant, “I did not compare even in shallow”, even though I have some memory of looking at both.

If it makes you feel better, a while back there was a North Korean map on the Chinese polyconic-based projection to which I think I posted a link in this group.

• Gall-Bomford
• The Times

But it’s neither of those.

• Gall-Bomford
• The Times

Ooops. Now I am the confused one. I was sure that the Times does not have equally spaced meridians along the equator.
As for the Gall-Bomford – yeah, I I really had forgotten that one.

I had, in searches related to this most recent find, run across, once again, another map on a mysterious pseudocylindrical projection. But this one was from Canada.
Just now, I managed to find a larger-scale image of the map, and I learned it's available under the Open Government License 2.0, which is nice.
And in the text, now readable, of the larger-scale image, I learned it was on the Winkel II projection.
This is the arithmetic mean of an equirectangular projection and the Apian II projection - one source erroneously described it as the arithmetic mean of an equirectangular projection and the Mollweide projection instead, I also learned, from this page.
Incidentally, the author of that page noted that he preferred the Winkel-Snyder to the Winkel II. Not only did I disagree, but thinking about the matter, I realized what I think I would prefer - I'll try to expand my program to draw it, so as to see if it actually is as attractive in appearance as I am hoping - the arithmetic mean between the Apian II projection and the Miller Cylindrical projection.
