Not familiar with geo stuff / DGGS. Is H3 not congruent because hexagons, unlike squares or triangles, do not tile the plane perfectly?
I mean: could a system using hexagons ever be congruent?
- urschrei 8mo agoHexagons do tile the Euclidean plane perfectly. They are the largest of the three n-gons that do so.
- rockinghigh 8mo agoThat's not true when tiling the Earth though. You need 12 pentagons to close the shape on every zoom level, you can't tile the Earth with just hexagons. That's also why footballs stitch together pentagons and hexagons.
