So which of these is your favorite? I really like the Cahill Butterfly

[@precisa_]

I think Dymaxion Fuller is my favorite projection since it can be used to recreate Earth without needing to distort proportions, for example, the earth 1 to 1 in minecraft uses a version of the Dymaxion projection, the only downside it has is the lack of direction

[@GSLindo]

You are português

[@quadded]

I love the canters W34

[@IVaV1]

Robinson for me.

[@lipsarath8728]

My favourite map projection is The Robinson Projection.

[@Nikioko]

6:45: The transverse Marcator is similar to the Mercator, but instead of the equator, the cylinder touches the earth's surface on the 0° and 180° meridians. So the toilet paper core is horizontal, not vertical. Therefore the biggest distortion is at 90°W and 90°E meridians (the straight horizontal lines through the poles) whose intersections with the equator are stretched to infinity like the poles in the true Mercator projection (parallel lines intersect in infinity). The choice of the 0°/180° meridians is quite random, another great circle as the contact line between cylinder (e.g. the 60°W/120°E meridians) and ball leads to different results. In That case, the biggest distortion would be at 150°W and 30°E.

[@cheydinal5401]

The Dymaxion-Fuller Map (triangles that are put next to each other) is often used to show the origin and spread of mankind from Africa, to other continents

[@General.Knowledge]

I didn't know that! That's really cool

[@旭球]

Yes, it's good for showing the nearness and interconnectedness of landmasses

[@skanthavelu]

I like that map as it more accurately depicts the actual shapes and sizes of each landmass. And though I am not a flat earther, I also like the Flat Earth maps as like the Dymaxion Fuller map, they show the actual sizes of the landmasses, albeit Antarctica looks like a giant wall of ice and many of them distort the sizes of lands south of the Equator. I wish that a map based on both the Flat Earth map and the Dymaxion Fuller map was used as the official world map as it would accurately show the sizes.

I would say that my favorite depends on What I’m using them for, for example, if I want to do a size comparison, I would use the Gall-Peters projection, if i hypotheticlly were stuck in the ocean, I would’ve used the Mercator projection. If I became a teacher in the future, I would use either the Winel Tripel projection or Robinson’s projection, if I want it change my view of the world, I would probably use other interesting maps, although, this whole thing with projections is Why I prefer a globe

[@okaro6595]

Why would you use the Gall-Peters projection instead of for example Equal Earth projection? There are several projections that preserve the area. Gall-Peters is the worst one. en.wikipedia.org/wiki/Equal_Earth_projection Fuck Gall-Peters. It is nothing but woke politics,

[@CEKROM]

7:33 Best picture =D

[@General.Knowledge]

It's really funny

[@Nikioko]

1:28: The Mercator projection is important in navigation because it has correct angles. The great circles (except meridians and the equator) are distorted, however. So a plane flying from Europe to New York over the southern tip of Greenland seemingly flies a curve, but in reality it is a straight line. The Mercator projection is a cylindrical projection as a cylinder is wrapped around the earth, touching it at the equator. The projection rays start from the center of the earth, therefore the poles are stretched to infinity. The Behrmann (not Berhmann) projection is also a cylindrical projection, but here projection rays are parallel to the earth's rotational axis, so distances near the poles are distorted to zero.

[@jessehendrix2661]

I forgot the name of the projection, but there was one which represented the northern and southern hemispheres with two circles, with the poles in the center. The lines of latitude were equal distances apart. It was printed on a double-sided disc, and you could fairly accurately find distance and direction by stretching a string between the two points. It seemed like a good compromise between accuracy and intelligibility if you needed both and could only have one map. Of course a globe is the best way to go, with the only downside being that you can't see the whole earth at once and it can't be shared as an image.

[@Nikioko]

9:34: Those triangles are nets of tetrahedra. The left one has the north pole in the center of a face and the south pole on a corner, the right one the other way around. 10:34: Those eight triangles are the net of an octahedron. It is a projection of a spherical surface onto the faces of that octahedron. 11:16: And finally in this one, the surface of the earth is projected onto an icosahedron which is the closest to a sphere among the Platonic polyhedra.

[@daniels.iparraguirre6077]

When you say, in the Mercator projection, "it inflates the sizes" towards the poles, (away from the equator), you mean the scale increases with increasing distance from the equator. Right?

Who knew maps and mapping was so complex, yet so precise?

Fuller projection, physical map, north pole at the center, no markings, no triangles, the oceans fill everything around the continents outside of the actual triangles of the projection. Thats the coolest map ever! No countries to kill each other for. Eurasia+ is rotated right 90°, Americas rotated left 90°. Breaks the usual patterns for maps, feels uniting.

Couldn’t they just use math to convert it and make it flat? I don’t get why this is a problem. Take redraw it and make it accurate and flat. When he shows the gif couldn’t they keep it like that and attach the countries so the size and shape stays accurate

[@Nikioko]

12:20: The Schjerning I is a conical projection which has the purpose to depict Russia as a whole with only very little distortion. Therefore it is very accurate around 60°N latitude and is very distorted on the southern hemisphere.

Mercator Projection for the "Win"! Which Map Projection do you "Prefer"?

[@GeHeum]

Another fun projection is the Euler projection: it is mathematically the best possible projection but it is completely impractical because the earth is projected on a very long line that wraps around many times

[@General.Knowledge]

Yeah it doesn't look very practical LOL

[@HistoricHomePlans]

The Goode (Interrupted) projection has always been one of my favorites. It gets the relative sizes of the continents fairly close and it keeps the longitude lines nearly straight. You only get a lot of distortion in the easternmost part of Russia. www.giss.nasa.gov/tools/gprojector/help/projections/GoodeHomolosine-Interrupted.png

[@General.Knowledge]

I agree! It's definitely in the top 3 for me

[@quadded]

it was used purely to depict Europe so it looked a lot better

[@Nikioko]

They didn't. But they knew that the earth is a sphere with 40,000 km circumference. Eratosthenes calculated that.

[@General.Knowledge]

They didn't! The map I showed is just a current reproduction of the world using the mathematical model that they used for their maps at the time.

[@Jeancahu]

they understood that with sticks and sun's shadows, some ignorant people from our era can't figure that even with smartphones, computers, space station evidence etc

[@GeographyWorld]

I'd recommend looking up the Authagraphic projection. It has very little domistortion, divides the world into 96 triangles and can be tiled together in many ways.

Geographer here: the orange isn't really a good representation of the Earth. Earth is a spheroid. Imagine trying to make a ball out of play-doh. It kinda looks lumpy when making it round

[@GeHeum]

The main reason for the symmetry around the equator is that the earth rotates around it so it becomes a natural choice for a symmetry line. In other words the reason is purely physical, mathematically there is no reason to choose that particular line.

[@General.Knowledge]

Ah ok! Thanks

You are applying the projections on a small scale to depict the globe. Mercator is used for navigation at much larger scales as points seen will be at the same bearing on the chart. Transverse Mercator is used for largest scale navigation charts inside ports and harbors. The line you drew on the globe is called a rum line and over the distance of oceans is the long way.

[@hpnk-ek8dr]

I think it comes down to lack of insentive to change. We have used that projection for very long, for det reason of navigation and correct shapes. Now that navigation is less of an issue we should change, people just do not care enough about it." So what he gets the sizes wrong, he knows were the countries are and their shape good enough". Also some suspect officials are against change since it makes their coutry look bigger. Many world powers through history are in the northern part of the globe so gets bonus, but that is kind of conspiracy theory.
