First thought: "this looks like what we used at Uber."
Sure enough, it is. It works well IIRC and there's a lot of interesting math surrounding it. Some of our internal tools we had access to at the time (now, presumably, under lock and key) had maps laid out in hexagons.
E: Some of the visualizers linked here seem a bit weird. I could be mis-remembering things, but the hexagons were WAY smaller than some of the visualizers here. I remember looking at the SF map and there was a lot of granularity even in the city center. Like I said though, could be mis-remembering.
It wasn't that granular. Maybe a few blocks of the city in size, give or take. The visualizers I'm seeing have a single hexagon span the entirety of Austin, TX for reference. At least in Uber's usecase, that was less than useful.
It’s a hierarchy… so you can take your pick of granularity? Only thing that matters is min, max and step-size.
Unless we’re talking about different things, I’m not clear why we’re not assuming the tool you remember chose h10 or whatever level was actually useful to it, where the visualizations chose h5
