I'm giving a workshop about #OpenStreetMap's Overpass query language on Saturday evening at #gpn23
It's a very powerful and useful tool, allowing for things such as custom queries, maps, statiscs, OSINT, or finding mistakes in OSM's data.
Unfortunately it's not the most intuitive thing, but we'll get you there during the workshop.
There are limited seats available and registration is mandatory: https://pretix.entropia.de/entropia/gpn23-workshops/89/
