I recall when I first saw Ubers’s H3[1], it really reminded me of healpix (from grad school). I know the algorithm is different but similar problem space: “given a point on a sphere, assign it to a stable cell ID”

I used healpy[1] once during my undergraduate years. It was a summer project to develop an algorithm to find void galaxies.

Love the HEALPix scheme, super useful for indexing too (some similar characteristics to geohashes).
