UK maps testing feedback

[neilvv]

A couple of issues I've noticed when testing generated tiles for the UK:

1. Vegetation obscures other landcover i.e. rock. I changed max opacity to 0.8 which worked for me.
2. service != driveway is quite an aggressive filter leading to disconnected sections of path in some areas. Arguably misclassification upstream but I needed to remove these filters in my case.
3. Bridleways are missing but that's a process.lua issue which I raised elsewhere.

Thanks for the great project!

service != driveway is quite problematic indeed. the choice is between having roads cluttered with driveways and occasional missing bits. if there was concise tagging in one form or another to distinguish "clutter" driveways from "driveways integral to the road network" i would reconmsider.
