   Yeah we're spherical mostly because working in spherical coordinates let's you not have to worry about the projection. S2Cells are really just nodes in a quadtree, the difference being our quad tree is implicit, you can (and we d

   Howdy, I work on S2 [1] so I have questions! How do you deal with polygons that cross the antimeridian? The indexing structure you've come up with seems very interesting. In spherical coordinates line sweep algorithms like that are a

   I'd be interested in hearing if you have more info on this.

   We have a parallel copy that indexes our intranet but other than that we use the same one everyone else does.

   S2 wouldn't be a bad choice, it lets you compute "coverings" of arbitrary regions as S2 cells, with variable resolution. Fixed size is trickier but is probably doable, especially if you're allowed to null out unused cel
