Yes, that’s confusing, but these dates are correct.
Wagner published the projections that are nowadays (he himself didn’t use those numbers) called Wagner I and Wagner III in a paper that was published in 1932. Then, in 1949, he published the book »Kartographische Netzentwürfe«, in which he again presented some of the projections he had developed earlier, along with some new ones.
The ordinal numbers were added later (to my knowledge, by John P. Snyder), using the order in which they are shown in the 1949 book.
And since Wagner went from the equal-area projection, to the projection with some amount of areal distortion, to the one with equally spaced parallels, they are now called Wagner I, II, and III, although they were originally published in a different chronological order.

Yes, I know the Waterman butterfly, and I’d love to add it to the website, but no software that I use is able to generate it. Thus, I can’t create the images that I use for all the other projections.
At some point in the future, I’m going to add a post to the blog, listing »the missing projections« that I’m not showing yet for this reasons. It’ll include the Waterman as well as the Dymaxion, Cahill-Keyes, Authagraph…

Thanks for your informative projection website! I'm working on Mapvision, a GEO-portal with international info about carto/geo/topo/hydrography, and much more global geo-related info. Sometime this year I will put a link to your site at: http://www.mapvision.eu/node/m…
Best regards, Peter.

In that vein... This is a very useful website, but from a professional standpoint, it would help if there more citations to sources, esp. for some of the more esoteric projections.

It was made using Flex Projector, I grabbed it from the gallery of that application:
http://flexprojector.com/galle…
I don’t know how it was mixed exactly, since FP offers a few options.
About the sources and citations: Good point!
I’m going to add more information, but I’ll do it bit by bit as time goes by.
Thank you for you comment and suggestion!

Great website! Quick question... what is meant by 'compromise', under the property column - for some projections?
Thanks
Tobias Jung
thank you! :-)
Quick answer: The term „compromise“ refers to projection that is neither equal-area, nor conformal or equidistant.
For more information about these properties, see:

Hope this helps!

I found my way to your very informative website because I am interested in Bucky Fuller's Dymaxion Map. I am wondering if you know of any digital developments of this map that allow for folding and other manipulations to reveal relationships not otherwise evident.
Please respond even if you don't know. That way I will know you received you question.
Much Thanks, Jean Gardner

I have a question, I could find out how it works, I read the papers but I am no good at either math and coding.
I have a map of a world from the german micro/virtual nations and it's in wagner VII and I would really love to get my hands on a merkator projection to put it on a globe/3D object.
It's a vectorgraphic but I am just unable to get it to work, or even how to start.
I.E.: How to get something like this: https://map-projections.net/d3…
Actually, doesn't need to be interactive at all.

The time I can put into the site is limited, and about a bunch of projections, I know next to nothing.
