I like searching for POIs via a query language on Overpass. My queries tend to be quite simple - “get all amenities of x type, in y area that have z tag”. The rendered map showing matching POIs is a nice-to-have, but not completely necessary.

What is the best way to do this offline, on Linux? (ideally using software already packaged for Debian, but that’s not vital).

I’m imagining a REPL that I can pass a downloaded map to, and then can query and see the results (in an ideal world, rendering them too).

It seems database schemas are close to what I want, but they seem to be designed more for people doing large scale complex queries and building bespoke databases just with the information they want.

Are these tools a good fit for my use case, or is there is a better/simpler way?

    I wish there was a way to subscribe to post comments on lemmy - I was looking for something like this myself.

      not sure about lemmy but there is a bell icon in piefed that I think subscribes to posts. I mention because its easy to miss.

      I am using the “favourite/save” function similar to this. I do not get noifications but I can go through my saves every now and then.

    How big are the “downloaded maps”?

    JOSM can do fairly complex queries with its search feature, maybe that satisfies your needs; but if you’re dealing with very large areas, they might overwhelm JOSM and not load in it.

    ETA: of course “downloaded maps”, if you mean .osm files, are just XML files, so it’s completely trivial to write simple scripts to search through them oneself

      Thank you for the tips! I should have been more precise in my question. The downloaded maps are ~150MB, in PBF format (although I would have been happy to use any other standard format if needed). I went with osmium tags-filter in the end, and it seems to be working well.

    Can osmium-tool do what you want?

    For example if I go here and export an osm file as pittsburg.osm: https://www.openstreetmap.org/export#map=18%2F40.440748%2F-79.999822

    Then I run osmium tags-filter pittsburg.osm n/amenity=library -o out.osm

    I get an out.osm with a bunch of libraries in it:

    I could’t find anything with a quick search, but maybe you could run the API server in an application container (e.g. Docker)? 🤔

    For more simple use cases, some apps on Flathub might be enough, for example Comaps

    (Also, I haven’t used JOSM in a while, but it might be worth checking that out as well to see if it can do want you want)

      Thank you. Of those I think JOSM is the most appealing, if it can directly show the results on the map. I’ll give it a go later just out of interest.

      I also gave osmium tags-filter a go and it’s meeting my needs for now.
