I am struggling to find a path between health facilities in Madagascar.
I think that because the road network (from OpenStreetMap) is limited, the functions in QGIS, such as
v.net.distance and shortest path (point to point) can't find a path.
The OSM tools plugin can't find a path either.
When I use the online routing mapper plugin, however, a path is always found.
Unfortunately, you can't import a shapefile, but you have to click on the coordinates to find a route. Since I have multiple health sites between which I would like to get a path, this is barely doable. My programming skills are very limited.
Is there a way to do it more efficiently or another plugin I should try or am I may be wrong to think the problem is due to a limited network?
