I think this might be my new favourite site on the internet. Wow! Everything I've been wanting to explore about projections at my fingertips! The _only_ drawback is that now that I've found this site, I won't feel so compelled to implement/write my own version of it, but hopefully I will find something else to do with my time. Thank you very much!

Can you look at Wagner II? It says the date was made after Wagner I, but also after Wagner III.

Thank you for your comment!

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.

Hi, Tobias,
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.
