Finish google buildings v3
Closed this issue · 1 comments
The google building data on source.coop only has a complete partitioned one based on google's v2. The v3 version is started, but it hasn't actually been partitioned yet.
The idea was to try a few different tools to partition and write up comparisons, just like I did for convert - https://cholmes.medium.com/performance-explorations-of-geoparquet-and-duckdb-84c0185ed399
But overture came into the mix and bumped the priority. There are lots of learnings from there, and many of the tools built for overture could be made more generic (#14 is the ticket for that). It'd be nice to just 'finish' v3 of google buildings in at least one partition, with row groups, so it can be used in get-buildings (ticket #15), so that one doesn't just work with v2 which is less countries.
This is done, v3 is now the default at https://beta.source.coop/cholmes/google-open-buildings and v2 was moved to a sub-folder.
