Some Metadata could be derived from the scraps we have in therion.
That will not be 100% accurate, of course, but for ecample if a
centerline shot crosses some pit, this could provide useful routing
information (because we can infer that we need rope and climbing gear
for this leg). Or from the passage dimensions we can deduce if that is
easily walkable or we need to crouch.
We could make a "routing map" as we know which stations we crossed, and
put together a map containing all scraps with the stations...

Awesome!
That is nifty. I've wanted this functionality quite often too.
I would love for that to be built in to Aven, so it could actually
highlight the route too (you know the problem, you give someone an
inch
they ask for a mile).
It's probably not that hard to do. The UI will be more work than the
routing. Of course what we really want is to apply normal routing
algorithms to the cave network (the graphhopper library is my
favourite as it's fast enough to make routing dragable), and include
weighting metadata so we could do somthing slightly more sophisticated
than 'shortest'. ('quickest', and 'least gear' are probably
useful). Being able to have dragable routing with timings (and maybe
tackle lists one day!) would be very nice, but relies on a lot of
metadata being available sonehow that currently isn't.

Annoyingly it seems not to be packaged yet. That can be fixed.
