Hi Thomas, thank you for the snippet, I succesfully tried it :) For my convinience, I wrote a small wrapper to ease the call: - It references my fixed aven file - It has parameters 1 and 2 reference the respective stations ------snip shortestPath.py------ #!/usr/bin/python # # Wrapperskript fuer survex.py um den kuerzesten Pfad zwischen zwei Stations zu errechnen. # # Bsp: Eingang -> Brueckenhalle: $ ./shortestPath.py Hirlatzhoehle.Zubringer.1.1.0 Hirlatzhoehle.Alter_Teil.2.1.55 import sys filename = "../Hirlatzhoehle/Hirlatz.th.3d" station_from = sys.argv[1] station_to = sys.argv[2] from survex import Survex3D survey = Survex3D(filename) length, p = survey.shortestpath(station_from, station_to) upwards = sum(max(0, t.z - f.z) for (f, t) in zip(p[:-1], p[1:])) downwards = sum(min(0, t.z - f.z) for (f, t) in zip(p[:-1], p[1:])) print("Shortest route length:", length / 100, "m") print("Cumulated height going upwards:", upwards / 100, "m") print("Cumulated depth going downwards:", downwards / 100, "m") ------snip------ Example call (Entrance to the Fragezeichenbiwak): $ ./shortestPath.py Hirlatzhoehle.Zubringer.1.1.0 Hirlatzhoehle.Donnerbach.70.1.19 ('Shortest route length:', 6773.091436823018, 'm') ('Cumulated height going upwards:', 781, 'm') ('Cumulated depth going downwards:', -770, 'm') Thank you! (nonetheless it would be awesome to get some more feature rich integrated function in therion and/or aven) Am 2021-11-28 18:49, schrieb Thomas Holder:
Hi Benedikt and Olly,
I implemented such functionality (not the visualization) a while ago as a little exercise in Python. If you know how to run a Python script, then you might find this useful.
First download this file: https://raw.githubusercontent.com/speleo3/inkscape-speleo/master/extensions/...
Then run this code (replace the file name and station names):
filename = "smk-arge.3d" station_from = "p87" station_to = "115.commando.105"
from survex import Survex3D survey = Survex3D(filename) length, p = survey.shortestpath(station_from, station_to) upwards = sum(max(0, t.z - f.z) for (f, t) in zip(p[:-1], p[1:])) downwards = sum(min(0, t.z - f.z) for (f, t) in zip(p[:-1], p[1:])) print("Shortest route length:", length / 100, "m") print("Cumulated height going upwards:", upwards / 100, "m") print("Cumulated depth going downwards:", downwards / 100, "m")
Cheers, Thomas

i would want to get some advanced statistics regarding lengths in a very big cave (130km/Hirlatz).
Basicly i want to supply two stations and get the following data for the shortest path: - length of shots - cumulated height for shots going upwards - cumulative depth for shots going downwards - optionally it would be cool to be able to somehow visualize the route in aven/loch, or in a therion map output
Is this possible already?
I don't think so.
Someone was working on it, but I guess it didn't come to anything as that was 2016:
