I was thinking about this, Nostr profiles with geo coordinates could be interesting for this type of mapping.
Discussion
There is ongoing discussion of that here:
Interesting, I'll followup there as well.
I'll have to look into how this could be used for geospacial location of a merchant (perhaps with NIP-15 Marketplaces) and for profiles.
Could also be interesting to be able to list in a broad geographic area, rather than specific to the meter.
Thus you could search for stores in a geographic region as well as products and services, similar to Bitcoin Jungle, Bitcoin Beach, Oshi and BTC Map.
Is recreating Open Street Map on nostr feasible?
Seems a stretch.
Optionally geocoding notes would be great.
