[mkgmap-dev] Line direction flag, merging etc

Tue May 18 14:53:06 BST 2021

Hi Gerd

The code in low-res-opt looks like ignore-oneway-for-lines.patch. The
disadvantage of this, as I see it, is that has-direction can't be
forced false for one-way roads.

I think my version is clearer.

Considering substitute lines from /overlays:

I had intended that they all (first and duplicates) have the same has
-direction value as the original.

An alternative is that the first has the original has-direction value
and the duplicate set has-direction solely from lineTypesWithDirection.

I don't know which is better.
