Talk:977: Map Projections

I have a Plate Carrée hanging on my wall myself. Never failed me yet. Davidy²²[talk] 07:05, 2 February 2013 (UTC)

I like the Azimuthal Equidistant (equatorial aspect) the best. - not Pennpenn. 108.162.221.43 01:15, 17 December 2015 (UTC)

You can explore and compare different map projections and their distortions (using Tissot’s indicatrix and triangulation of sphere) in an interactive blog post The problem with maps by Michael Davis --JakubNarebski (talk) 14:58, 26 May 2017 (UTC)

Go check out that site carefully though most of the data is accurate, some of the media is not, for example the two side by side Google maps satellite images of cars and the text saying how a map projection changes the apparent size of the cars. Well if you open up both links you will see they are at different zoom levels, one at a scale of 50 feet per unit and the other at 100 feet so yes being twice the zoom the cars are going to appear larger then the image right next to it. 162.158.62.231 12:04, 23 August 2017 (UTC)

Btw, this comic is given in What Does Earth Look Like? of Vsause where these projections are discussed. --Ата ^(talk) 10:38, 3 September 2017 (UTC)

Dymaxion

Dymaxion is clearly the best. There's nothing like a map made out of an unfolded d20. Alpha (talk) 19:43, 23 February 2013 (UTC)

Makes you wonder what if a dodecahedron had been used instead of an icosahedron. --Quicksilver (talk) 18:02, 17 August 2013 (UTC)

Quincunx

Peirce Quincuncial has 4 non-conformal points, but not the 4 corners, which are the south pole, but instead are the 4 midpoints of the sides. These are on the equator and seem to be 90 degrees apart.--DrMath 06:30, 30 August 2013 (UTC)

I love Peirce Quincuncial, yet I slept throughout that "Inception". 141.101.99.228 11:36, 27 January 2014 (UTC)

I'm surprised nobody thought of "really looking at your hands" as a hint that person that likes this projection is under influence of LSD or similar drug. As this surely is a thing that you do. (and you'll think of it next time you smoke your joint - inception!) --108.162.254.137 17:29, 7 December 2014 (UTC)

Plus it has a picture of a man looking at his hand and a man looking at the man looking at his hand. I used Google News BEFORE it was clickbait (talk) 14:39, 22 January 2015 (UTC)

xkcd 1051's title text - "meta lucid dreaming". I really got excited that there was an article about and ironically, it leads to meta and lucid dreaming separately. 173.245.55.67 21:23, 25 March 2014 (UTC)BK201

The common video game trope of "the far east of the world is connected to the far west, and the far north likewise to the far south" is popularly resolved by saying that those game worlds are toroidal shapes. (For a particular reference, I am thinking of the SNES and PSX era Final Fantasy games (4-9.)) But sometime in the last year, I got the idea that you could also resolve that geographical conflict (and claim they are spherical) by the logic that the "world map" you see in those games (where they have one) is a Peirce Qunincuncial map. Is my logic sound? Boct1584 (talk) 15:31, 28 March 2015 (UTC)

The explanation for the Peirce Quincuncial seems to miss the fact that Randall is implying that anyone who likes this map is most likely high. Getting lost in deep thought over things like your hands, or sitting in a dark theater for 6 hours to wrap your head around Inception...these are all very stereotypical "has smoke a lot of marijuana" behaviors. 108.162.216.21 (talk) (please sign your comments with ~~~~)

The Quincuncial map is one of few maps that can tile infinite plane such that any 2 arbitrarily close points on the plane correspond to 2 arbitrarily close points on globe and vice versa.

Waterman

In actual fact, the Waterman butterfly map used a truncated octahedron based upon the mathematics of close packing of spheres and is not at all based upon any of CaHill's work/math. -- steve waterman 65.92.20.61 (talk) (please sign your comments with ~~~~)

Perhaps the explanation should mention that Waterman himself signed up at forum.xkcd.com and vigorously denied that his map has anything to do with Cahill. At the time, it was unclear whether the account was really Waterman, or just a troll trying to make him look bad. - Frankie (talk) 21:39, 25 March 2014 (UTC)

Kavrayskiy VII

Kavrayskiy is the best projection, despite being so far out of the mainstream that no-one west of Ukraine has seen one for the past 20 years. 173.245.54.64 (talk) (please sign your comments with ~~~~)

Wow, I looked into it and it really seems like an excellent projection. It's been a while since I've looked at projections but I think it's my new favourite as it has everything that I've been looking for in a projection. It's a more accurate (in extremes) and more pleasing Robinson projection that still has a reasonable amount cut off the top. Also, the indicatrix for it is very simple, as is the formula, and simple things please simple minds (like mine, apparently) -- without taking it to an extreme like the equirectangular projection does. I swear I've come across it before, but then again I grew up in a country which wasn't far from the Eastern Bloc. 141.101.98.214 14:51, 5 November 2014 (UTC)

Sphere

To be fair, what is drawn is an orthographic azimuthal projection.--108.162.216.153 18:59, 14 December 2014 (UTC)

GLOBES ARE THE BEST although my enormous Winkel Tripel hasn't done too bad. 108.162.219.9 (talk) (please sign your comments with ~~~~)

Airline food is never microwaved, and is chilled rather than frozen. Also the problems aren't limited to storage and re-heating, there are technical considerations with low air pressure, dehydrated air etc. and concerns over strong smells.

Wording disagreement

Loodog and I disagree about the wording of the Peters map explanation.

The previous version of the text (written by LCarsos in 2012):

Anyone who loves such a politically charged map that has become popular by way of marketing stunts, Randall would rather not have anything to do with.

Loodog's version of the text:

The implication is that the fans of this map are pompously concerned with social justice, and willing either to lie or convey marketing mistruths to promote that cause.

I believe Loodog's wording is excessively non-neutral, and the old wording should be restored. - Frankie (talk) 19:29, 20 November 2019 (UTC)

FWIW, I disagree that Peters fans are "pompously concerned with social justice". IMO, they are just assholes who enjoy using the terminology of social justice as their cudgel. People who genuinely care about social justice don't use Peters.

Amnesty International, Human Rights Watch, and the International Organization for Migration are three of the world's largest social justice organizations. Each of them has been described as "pompous" by detractors. None of them use Peters map projection. AI & HRW use a mix of Hobo-Dyer, Equirectangular, and probably Mercator. IOM uses something rounded (probably Robinson or W-T), Equirectangular, and Mercator. - Frankie (talk) 19:34, 20 November 2019 (UTC)

I'm inclined to agree; certainly we should be careful about calling people "pompous" in the article voice. I went back to the older wording but added "...and false claims..." after marketing stunts, which seems to have been the main thing that the person who changed it objected to and which can be stated more neutrally like that. --Aquillion (talk) 07:13, 9 January 2023 (UTC)

Hemispheric Interrupted Mollweide

Still disappointed that Randall didn't include the BEST projection: Interrupted Mollweide Hemispheres. It combines key aspects from the clean math of Equirectangular, the values of Hobo-Dyer, the circularity of Van Der Grinten, the flattening of Homolosine, and the hipness of Winkel Tripel. - Frankie (talk) 15:09, 31 October 2022 (UTC)

Maybe next time While False (museum | talk | contributions | logs | rights) 19:00, 31 October 2022 (UTC)

i like peirce quincuncial and plate carree (bonus points the fact it's the oldest one). mercator is a bit meh, but let's give it credit for being one of the first projections (in fact it is the second oldest projection). gall-peters is the ugliest projection i've seen, and hobo-dyer is second ugliest. the butterfly one is also good but a bit weird, and the ichosaedron one that i forgot the name is... weird. like, wtf is that, it doesn't even look like a map, idk, where's europe there An user who has no account yet (talk) 18:31, 6 September 2023 (UTC)

For the "icosahedron one", you mean the Dymaxion? In which case, Europe is in the topmost trapezoid (left, as opposed to the two triangles top-right). See Africa (Madagascar crossing an edge) in one corner, see the 'squiggle' of the Med and then Europe (rotated maybe 150 degrees over) crammed in the right of the extrusion. 172.71.242.76 21:47, 6 September 2023 (UTC)

It should maybe be explained that the concept of determining what someone's personality is like by what map they prefer is itself projection -- Mesoseven (talk) 05:20, 3 January 2024 (please sign your comments with ~~~~)

Might be worth disambiguating/adding to the projection (psychology) link in the Title Text section. I mean, they're not totally the same thing, but could be dealt with together with the right wording. (PS, I shuffled/reformatted your contribution. You did 'sign', but not sign, and you can check the layout of the handy wikilink template we use here if you read how I've made your link; and my own without any replacement text.
