Hi,

I’m trying to compute the routes between two layers of points. Initially, I had two layers of points that did not have the same number of points (some departure points have several destinations). I was hoping that using a unique ID would allow them to join the departure and arrival points, but I was not successful.

So I subsequently duplicated the departure points so that I had as many departure points as arrival points. I ordered the two layers in the same order (departure points and arrival points) and I computed routes using the layer mode “Row-by-row”. However, as can be seen in the following screenshot, the FROM_ID and TO_ID fields are different, what it means that the routes obtained join the points in a way that I don’t understand. I don’t understand in which order he considers the rows to perform the “Row-by-row” calculation. Does someone have any idea how I could have at the exit, point A, ID XXX1 connected to point B, ID XXX1 and so on ?

Thanks for your help
