I have polylines from a network analysis representing public transport trips. These are multipart polylines.
I need to identify the starting point for each trip. However, using vertices to points to create starting points, I get starting points for every part of the line. To get only one point, I tried transforming the lines with multipart to single part and then unsplit, as suggested here, as well as dissolve but none of them worked.
Fyi, the lines have IDs.
