[Qgis-user] help with shortest-path/network analysis (multiple origins to multiple destinations)

[Francesca Parente]

Hello everyone,

I'd need to identify optimal destinations (within a point layer of
geolocated facilities) for each territory of a given set of possible
origins.
I already calculated a distance matrix between the two point-layers, and
also applied the distance-to-nearest-hub tool to generate a string layer
and identify the optimal facilities.
But I'd like to obtain a more realistic estimate, accounting for the roads
network (and ideally their travel times). With quite a few issues, I
finally managed to import an OSM road network from download.geofabrik.de
(in order to cover my area of interest, I had to merge two different
vectors fo Center and Southern Italy and then extract a focus spot in
between the two and save it as a lighter layer, otherwise it also took an
eternity to run every analysis).

So now my question would be: is there a tool to perform a layer-to-layer
shortest-path analysis that takes it into account?
All that I could find was either point-to-point or
layer-to-point/point-to-layer (I looked also at built-in network analysis
tool and Qneat3 plugin).

Any kind of inputs and suggestions will be more than welcome!
Thanks a lot for your support and have a good day,
Francesca
