Which map project did you decide to go with?
I'm running (
experimenting with, mostly)
PokemonGo-Map. It works pretty well and looks really nice, but it seems to have some trouble showing pokéstops that are
very close together. Some in my downtown park are just ~15 meters apart, and the nearest ones only showed one or the other at first. After a few scans, it managed to sort things out, though.
Still, very neat!
(I'm just running it on my local Mac at the moment.)
