Hi,
First let me thank for the excellent road-graph plugin. I tested it on
my city's sewage network to find connected sewage pipes. I was able to
configure to only follow directed lines (all our lines are digitized in
flow direction).
I have two questions/suggestions regarding the plugin:
1. If it can't find a connected route - there is no message/result at
all. Would it be possible to indicate the user that the plugin could not
calculate a route instead of just doing nothing? Otherwise the user
won't know if the plugin is still calculating or if it did not find a
route. Alternatively there could/should be a clearer indicator that the
plugin is still calculating.
2. what tolerances are used for the start/end points? How close do they
need to be to the vertex or a segment? As far as I can tell it does not
support/honour the snapping settings for the setting of the start and
end points?
Thanks for your comments!
Andreas
