Generation of Spatial Weights Matrix - How it works for Lines?

Hi,

I  am trying to understand how the spatial weights matrix is generated for a polyline shape file? I have tried the fixed distance option with Euclidean distance and left the distance threshold empty. After this, it detected a threshold value so that each feauture would have at least 1 neighbour. However, I could not understand the physical meaning of this calculated distance (note that, as far as I did the right things, it is not the euclidean distance between the start-end points of the polylines, nor the distance between their mid-points)!

Could someone please explain how it works for line objects, as the source is not sufficient.

Kind Regards,
Berk
