SH3 Globe: Mercator or Gall Peters projection

In SH, the degrees of longitude are always the same at 120 km. So a feature which is 55km long becomes stretched to 120 km long at 60 degrees latitude on the game map.

It would be nice if the SHIII world was actually round (like in the Microsoft flight sims). It would be a little more complicated to transfer a dot on the globe onto the flat map, but it would be well worth it: real distances and continent shapes/sizes and the possibility for real navigating using the sun and stars (with sun, moon, and planetary positions accurate for 1939-1945).

Well, I did my best attempt to speak only of 'Real World' degrees, and 'SH3 or game' kilometers. I never mentioned 'Real World'-kilometers in this thread.

But I guess I'm not the most eloquent these days.

Nah, maybe I'm just too tired. It's been a long week (and it only just started )

Thanks for all the replies.

Luno appears to have identified the type of map projection used by SH3 which is equirectangular. This is reinforced by what Wiki has to say "In particular, the plate carrée has become a de-facto standard for computer applications that process global maps, because of the particularly simple relationship between the position of an image pixel on the map and its corresponding geographic location on Earth".
