How to move all lines with line-offset to one side?

[pdrhlik]

Hi,

I create vector map tiles from OSM using tilemaker. I have my own style that focuses on hiking and shows coloured hiking routes. My issue is, that I want to display the coloured routes next to the paths. An obvious solution is to use the line-offset property but that doesn't work well because each path can have a different direction. Therefore, setting the same offset results in some routes being displayed on the right side of the path and some on the left side. I would like them all to be displayed on one side. It can even create unnecessary lines surrounding the path from both sides like on the screenshot:

What happens is that there are multiple relations that overlap a bit. They all have a red colour but have a different direction. Which is why each of the lines is displayed on a different side.

My question is, if anyone knows, how to tackle this? Is it possible to somehow ignore the direction so the lines could be offset more reliably? Or would I have to handle the raw data manually?

Thanks for any ideas.

Cheers,
Patrik

I don't think there's an easy fix besides changing the tiles' data to fit your needs. But you could check if someone in the slack channel may know more...

Thanks for the reply, I'll give it a shot there.
