I have a project to use QGIS to track fishing activities (product goes from boat to fisheries to processors to factories...). All layers have coordinates and I managed to map them but now I´m trying to connect the different points with their respective connections. I´ve tried Flowmapper but can´t seem to work out the projection; I tried Points2one but since the same point can go to two different routes, I don´t think it´s the right plugin; lastly, I´m thinking of trying the PointstoPaths although I think I would have to create excel tables for each individual element.
How would one connect the different attributes to each other through the relations tab in the layers properties?
Is it possible to somehow tell QGIS what the relations are and then the program would connect those points?
