Just as an example, the context meeting is att the attached location:
50°45’7” / 5°35’19”

If you want official data you can try the Belgian cadastre:
https://data.gov.be/en/dataset/tt098dcb-f5c7-49b8-8e0b-7c3811630d85 :-)
Yet another format? No way. I managed to go big so for instance the area
where the colorado user group is located:
https://www.openstreetmap.org/export#map=12/40.5117/-104.9496
produces a 122 MB osm file
https://overpass-api.de/api/map?bbox=-105.1817,40.4096,-104.9493,40.6272
that gets turned into a 15 MB metapost file that becomes an 8.7 MB pdf
file. Unfortunately it takes 36 seconds to be produced (9 seconds xml
loading, 17 seconds map processing, 3 seconds mp -- which is not that
bad -- and some 2.56 seconds pdf production) plus some 3 GB memory but
that's still under my limit. Maybe a decent modern desktop can do it in
half that time, who knows.
Of course the rather detailed colorfull image is a challenge for the pdf
viewer but (sumatra) it manages and one can then zoom in a lot. I tried
the whole of slovenia to prove myself to mojca but overran my quota for
that api (and I'm not in the mood to install all kind of stuff here).
