Foursquare just open sourced their 100 million place point of interest dataset! Some notes on poking around with it using DuckDB (it's Parquet files on S3) simonwillison.net/2024/Nov/20/

@ianthetechie @simon I hope Apple Maps ingests these to finally get better in our city :)

@ctietze @simon seriously! I have always been pleasantly surprised by the 4sq data in areas where major players fail miserably (like Seoul). Will definitely be adding this to our geocoding pipeline soon at @stadiamaps… also feels like the perfect time to build that app I keep thinking about @zverik. This would enable OSM mappers to build a “hit list” of places to either add or confirm in EveryDoor. And 4sq could use that in turn to update their validation confidence. Everyone wins!

Will need a statement on licensing from the LWG, can check the contents if that is favourable :)

@thibaultmol not sure - maybe? Apache 2 is more permissive (doesn't have a sharealike clause)

@simon it's interesting how they're openstreetmap minded supposedly but don't mention anything about osm importability

Steffo

@simon #OpenStreetMap might benefit from this! (Or not. I don’t know much about importing external datasets there…)

@simon does anybody knows where this data comes from?

Thibault Molleman🇧🇪 🌈🐝

@morganist @simon Atleast in the past, Foursquare used to be an app that people used to share the places they went to. It was sort of gamifiied. and obv people would add poi's to foursquare because otherwise they couldn't check in there.
But what eventually was renamed to 'foursquare swarm' is now discontinued, so yeah. don't know how recent this data would be

@thibaultmol @morganist @simon It (the foursquare Swarm app) had very new things from Munich in it just last week.

And Swarm hasn't been discontinued as of yet, I think (it worked on my phone just a second ago).
