I've been working on this over the past week after reading about it in https://news.ycombinator.com/item?id=40492234.

I found an interesting API that returns the largest network in a given tile but have failed to find the algorithm used to encode the `X-tilekey` field used for positioning. I got close with morton encoding and linear regression which works for most of the UK but deviates as you go North/South.

I'm posting this both to show what I've done and ask for help. If anyone knows how tile keys might work, please let me know (either here or in an issue). A small data sample: https://github.com/acheong08/apple-corelocation-experiments/...

Thank you.

Edit: I was initially planning on showing this way later but I can’t figure out around this problem. Thought HN would be the best place to ask since I’m probably the dumbest user here
