I built one, tracking fleet vehicles with a custom box, using tiled maps, on behalf of Vodafone, back in 2002. I still remember I wrote a basic trans-mercator library too!

Of course Mercator projection may go out of fashion soon https://www.independent.co.uk/news/world/africa/world-map-eq... :)

Hope I'm called back to update the library ;)

I believe the library mentioned in the article should be this one https://geodyssey.github.io/overview/overview.html and here https://www.lukatela.com/geodyssey/

The author says:

"It used Voronoi Cells and reduced most math to 8- and 16-bit integer calculations with one or two single-precision floating-point calculations."

I wonder if it can be used to speed up LLM inference.
