Missing tertiary and highway links in cities #19

Closed atorger closed 3 years ago

There's a bug causing gatutyp layer always override KLASS, meaning that we get residential for all but the largest roads inside cities. Link is not processed at all currently.

I've now tested the highway _link trick. Neat.

However, it is a bit "dangerous". What it does is subtracting FPV-KLASS from DoU-KLASS, and looking at what's left. It can only be used on roads that are included in FPV-klass, ie primary and up, and it trusts that DoU-KLASS includes links and that FPV-KLASS does not, so the difference = links.

I tested it on Malmö and it sort of works, but not quite. I'm hesitant to use it due to that it's just a side-effect how these layers happen to be delivered, rather than a layer actually pointing out links. It also is of limited value to include link tagging as ~100% of all these roads are already mapped, and 50+% will not match on highway type anyway so doing import there will mostly only be about refining geometry. A time saver for import is probably just to drop the highway tag (keep the others) and replace geometry to merge the rest.

So for now I won't include highway links in my translation..

Tertiary roads now show up in cities. Closing this.
