Show HN: Reverse Geocode REST API
github.comIf it's at all useful, here's the polygons for all the countries as of last January: https://raw.githubusercontent.com/daveross/offline-country-r...
Could be handy as some sort of fallback when one of your providers isn't available. That repo has the code to reverse geocode from a lat/long combo.
Hmmm you bring up a good point, having a file based provider type might be useful as the last fallback.
Also, the tool already supports fallbacks, so if a provider is offline or what have you it will try the next provider in line and so on.
