I'm looking to label a series of lines based on a direction of the trail rather than any cardinal direction (east to west, north to south, etc.) in QGIS 3.4 for Windows 11.
I've seen this answer, but this is to follow points in a longitudinal direction (though it can be applied to latitudinal as well). This doesn't necessarily apply in my case as I'm (1) looking to do this for lines rather than points (so can't add a longitude field) and (2) I'm not following a single cardinal direction.
This is just an example with data that's quite limited. The actual number of lines I have exceed 200, so an automated (or semi-automated) way of doing this would be very helpful.
I'm not much of a coder so I'm not really brave enough to open up the console (nor do I even know how to open the console).
