Hi,
Does anyone have an idea of what might be the problem in below bug ?
I can reproduce it with spearfish data:
v.net input=roads@PERMANENT output=roads operation=nodes alayer=1 nlayer=2 -c
d.vect roads@user1
d.path map=roads@user1
Building graph:
Registering arcs ... 100%
Flattening the graph ... done.
Graph was built.
L: from M: to R: quit
pressing the left button gives:
Node 650: 594318.629202 4925368.174169
Erreur de segmentation
I have to present make a presentation of GRASS to colleagues next week, which might lead to the department opting for GRASS for classes in the future, and it would be great to be able to present the network analysis capacities.
I know I can use v.net.path, but this is a more complicated way (especially since it doesn't allow mouse-based choice of coordinates), so if anyone has an idea it would be very welcome.
Thanks,
Moritz
