Regardless of any distortion metrics, I find rounded corners more aesthetically pleasing. I really dislike pole lines with angled corners, except on cylindrical projections.PeteD wrote: ↑Fri Apr 07, 2023 5:51 amThe whole reason for averaging a pointed-pole parent projection with the equirectangular projection in the first place is to introduce a pole line. However, once you accept that you don't have to use the same parent projection for the y values that you use for the x values, it becomes apparent that you don't need to take the average with the equirectangular projection at all for the y values and you'll still have the same pole line. Taking the average of the equirectangular and Aitoff projections for the x values and just taking the Aitoff projection alone without any averaging for the y values gives a projection that's essentially the Winkel tripel but with rounded corners:

Re: Experimental projections
That's why the Mollweide looks so aesthetically
pleasing to me, except for it's skinny Africa. Of course that's why I like the Bromley rescaling even more.

Re: Experimental projections
As well as the Hammer, the Aitoff, Eckert III and Eckert IV.

Re: Experimental projections
As well as any of the Winkel II and Winkel Tripel among other rounded corner projections.
Re: Experimental projections
I agree. After all, the Earth is round.
In this paper on Flex Projector that mentions the design process of the natural Earth projection, five advantages of rounded corners are listed:
On the other hand, this study on map projection preferences found no statistically significant preference for pointed or rounded corners.
- They suggest that the projection represents a spherical Earth.
- Rounding corners and the related action of lessening the length of pole lines reduced the size of polar areas, thereby making Antarctica appear smaller.
- At the top and bottom of the projection, meridians converge inward toward implied poles, suggesting that the poles are in fact points instead of straight lines.
- Aesthetics: from iPod music players, to Jaguar automobiles to the Mona Lisa, curves convey classic elegance.
- The tightly rounded corners of the Natural Earth projection are unique among commonly used pseudocylindrical projections, helping to differentiate it.

Re: Experimental projections
Well, tastes differ. Obviously not everyone is going to agree with mine. At least "no statistically significant preference" means that about as many people agree with me as disagree.PeteD wrote: ↑Sat Apr 08, 2023 2:44 amOn the other hand, this study on map projection preferences found no statistically significant preference for pointed or rounded corners.
Also, umm, you forgot to actually enter the link.

Well, I do agree with your taste in rounded corners.Milo wrote: ↑Sat Apr 08, 2023 5:28 amWell, tastes differ. Obviously not everyone is going to agree with mine.
