Hi all,
I’m trying to create points at 1 m intervals along a line, with a sequential ID starting at 2000.
As shown in the screenshot below, I need the sequence to start at the south-western end of the line with ID 2000, then increase by 1 for every metre as it follows the line towards the north-east and then back towards the north-west.
So essentially:
- Start of line = ID 2000
- Next point, 1 m along the line = 2001
- Next point = 2002
- Continue incrementing by 1 following the actual direction/path of the line
I have tried using the DistanceChopper from the FME Hub to split the line into 1 m segments. I then calculate the X/Y coordinates of the start/end points, use a VertexCreator, and finally a Sorter based on the X coordinate.
This works up to the location marked X in my screenshot. However, because the line curves back on itself in the X direction, sorting by X no longer represents the correct order along the line.
What I really need is a way of ordering the generated points by their distance/position along the original line, rather than by their X or Y coordinates, and then assigning the sequential IDs starting from 2000.
Is there a better approach or transformer for achieving this?
Below the current workflow
Any suggestions would be very welcome. Thanks!
