I have a large dataset consisting of lines/polylines where I would like to join/merge the lines that touch / intersect. Each line has an individual ID and there are no common attributes I can use for a join operation. Is there a way to (spatially) join lines into segments of touching lines?
Screenshot of a selected line in a line segment (current situation):
It can be done in ArcGIS according to this post (link) among others.
FYI, the dataset is an extract from a pipeline network and I will examine which line segments that cross the most properties / parcels of land.
I'm using QGIS 2.14.0. I have no experience with python or GRASS yet.
