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: https://lists.survex.com/pipermail/survex/2016-October/002082.html Cheers, Olly _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
I think, when we would have some option to compile the shortest path between two statoins, this could easily leveraged to the multi-station approach (I would even do that manually if its not easily to be automated). Further wishes could be to be able to specify constraints as options, so for example to assign more path-cost to steep inclinations (shafts/pits) or sumps. The big question is, how this needs to be coded up, and more important, who can code it? Am 2021-11-29 9:21, schrieb Bruce Mutton:
