Map tiles fail to load at max zoom

[ThorntonMatthewD]

The maximum zoom on the map is currently set to 20, however at this zoom level the map tiles appear as solid grey images.

You can see it in action here: https://hackgvl.github.io/open-map-data-multi-layers-demo/?lat=34.851224882536776&lng=-82.39967912435533&zoom=20&maps=free-wi-fi-hotspots

I'm wondering if the max zoom needs to be 18 instead since it seems to be inclusive.

There's actually also a bigger issue with tiles in that we should probably find a better alternative than freeloading off of open street map's donation-based tile servers, which could change their policy at any time: https://operations.osmfoundation.org/policies/tiles/

My vote is for Spinal Map for the remainder of October. 🎃🤘

That is a really good point... I've seen some projects store their base tiles in a GitHub repo, but I'm not sure what limits we'd run into there in the long run.

Spinal Map looks amazing 😆. I could do some research on alternative options for tile servers. Is a PR to lower the zoom limit to 18 still wanted?

[ThorntonMatthewD]

I think for now that would be good. If/when a different source of tiles is put into place then perhaps it can be increased again (if supported).

#36 fixes #32

Thank you, @Alex-Grimes !!!
