Thanks Daan! I found the right projection center that allowed me to crop one face of the tetrahedron in 3 equal parts et voilà

Hi guys!Talking abou experimental projections... I did it again... A few days ago I was thinking about a projection on a tetrahedron with less disortion and still a nice shape. After a lot of shots I found this arrangment... I hope you like! Not exactly a rectangle but almost... Enjoy! tetra-concial...

Hi all, I know that somehow we are gone quite off-topic here but after the "guy doing push-ups map" I wanted to do the same but better. So... call me the crazy photoshop guy but I wanted to waste some time to get this. This map derives from the cube with some big manual work... grid is tot...

I don't know if I personally like the way eastern South America and western North America look in that particular one, but I certainly see the potential. Maybe I'll try something like what you suggested. Or at the very least, I'll mention conformality in the future work part of my conclusion and ho...

I tried to make a fully conformal projection with fairly low distortion of area and general shape using just the Lambert conic conformal: Nowadays, though, of course the biggest demand is for projections that are fully equal-area. Not new to me, I really like your website :D Check here https://www....

That's it. It's nothing more than an experiment... The outer shape is ugly but the overall look of lands is very nice to my eyes. I played with the conformal cube of Geocart (demo version, you can see the watermarks) and I found the parameter to have all land a little away from the cube vertexes. St...

Hi Justin! I have read all the paper. It sounds pretty clear to me even if I'm not so much into that level of mathematics. To be honest I already noticed the Danseiji maps in your MapDesigner and I find Danseiji IV absolutely great. The base idea is great, I totally like it. The only thing I would t...

Hi Daan, thanks, it's quite clear. Let's see if I understand: ESRI Shapefile is the only vector format recognized by Geocart. Each database consists in more files and is Geocart will use a specific line style based on what coverage is assigned to each database. Then if I have a different database fo...

Hello all, it's the first time I play around with Geocart so sorry if I'll do stupid questions... I'm trying to use Natural Earth vector databases and I have a few question I cannot find any answer in the manual. - River line width: is it possible to obtain a progressive width vector line for river ...

Check out also this intersting paper about polyhedral maps! https://inspire.redlands.edu/cgi/viewcontent.cgi?article=1110&context=gis_gradproj Even if I don't like so much the result, the idea is very good and I guess that using the conformal engine that Daan developed it's possible to obtain gr...
