Let me know if I understand correctly. You want a true to life sized map of earth? 😳
Comment on Denominator, go Mercator

Anyone know of a 2D map print of true size? All I’ve found print wise is Mercator or other such variations.

They want a 2d map of earth but with every continent to true size at scale, rather than Mercator projection where the northern hemisphere is expanded to increase their importance over the southern hemisphere.

Mercator wasn’t created in order to increase importance of the northern hemisphere, but to allow for directional rhumb lines to be drawn for shipping. For its intended purpose of navigation, it does an excellent job.

It may not be the intended purpose but I certainly does change how the world is seen by everyone using it to warp the mind’s eye to how the world actually physically is.

Exactl, this.

Ah that makes a lot more sense! 😅

I don’t know what you mean by “other such variations”, but maybe you are looking for a map with something like the Mollweide projection? That’s a bit of distortion in shape but trying to keep areas real.

What do they call the projections that have slices taken out of them at the oceans?
selokichtli@lemmy.ml 1 day ago
The projection is the mathematical transformation from the curved surface of the Earth to a mathematical surface. You can have types of projections based on the mathematical surface (conical, cylindrical…), or based on the features they want to rescue from this transformation (conformal, equal-area…), but, sorry, I’ve never heard of a classification based on these “slices”. Moreover, now that I think of it, even those projections we are familiar with have to be cut somewhere.

Another post in this thread had an example of one, called Goode’s Homolosine Equal-area Projection.

No, because Africa is larger than Asia, and this shows Asia as massive.
selokichtli@lemmy.ml 1 day ago
You may want to double check that, or you probably will need an imaginary map.

Africa: 30.3 million km²
Asia: 44 million km²
Nowhere near the difference Mercator projection maps make it out to be, but Asia definitely is larger.

Technically, the outer surface of a sphere is, itself, two-dimensional. It is, however, non-Euclidean and cannot be perfectly preserved in a Euclidean two-dimensional space.

Mathematically impossible, but you could try an Equal Area projection.
ChaoticNeutralCzech@feddit.org 1 day ago
Equal area projections usually preserve straight and perpendicular meridians and parallels. That’s neutral but then there’s the political decision of what latitude gets the correct aspect ratio. And Gall-Peters is not anti-colonialist if representing Africa correctly was your goal.

Essentially this. A true sized projection, it can be in any “cut” of the globe as long as all the continents are true to size.
