It's a bit bothersome they nudge you to install and use aws tools to download the data, instead of providing a plain CSV or JSON downloadable dump instead.

It's S3 so this works to list the bucket contents:

    curl -s "https://fsq-os-places-us-east-1.s3.amazonaws.com/?list-type=2&prefix=release/dt=2024-11-19/places/parquet/&delimiter=/"
And you can download a file called places-00000.snappy.parquet like this:

    curl -O "https://fsq-os-places-us-east-1.s3.amazonaws.com/release/dt=2024-11-19/places/parquet/places-00000.snappy.parquet"

I used to work for Nokia Maps (before it was renamed Here Maps) working on their places registry, which was a proprietary data set compiled from various sources of data with a similar amount of places. It was really messy data. Lots of duplicates, lots of stale data, lots of misleading data (e.g. hotels claiming to be right on the beach that in reality were a few kilometers away), etc. Part of my job was cleaning tha…

To be honest, this problem is unsolvable. The only API that's closest is Google Maps, I've just accepted it and gone all-in with them.

I also found it hard to deal with the AWS CLI and Parquet. I built this site so you can download it in CSV and Geopackage.
