As translit preprocesses your data I experimented a bit with an option "remove ways which are buildings". This was easily implemented. It removes only the the way (<way>....</way>). Not the nodes which make up the way. (that would require extra passing).

Maybe I could (for that) also remove all nodes with user="3dShapes" but that is just an idea... I did not investigate this.

I've implemented this as a filter using Osmosis (that was easy). The resulting tiles are about half a megabyte smaller, but I've not published one of the test runs yet.

But, regarding Translit, it's a bit of a bottleneck while processing on a multicore machine. Do you see a possibility to do the translation in parallel? Or, alternatively, you once wrote that you were working on integration into Mkgmap? Any progress?

Maybe, I'm using the default Mkgmap stylesheet so this should go into that stylesheet first. Perhaps you can contact the maintainer of the stylesheet (Marko Mäkelä, marko dot makela at iki dot fi)? He's also active on the Mkgmap mailinglist...

I previously contacted the mkgmap mailing list about this, they said, "Oh, we don't really want to add tags...bug the guy generating your maps."

Damnit, then why does one of the fella's at that mailinglist calls himself 'stylesheet maintainer'?

I'm sorry that this doesn't get resolved, but I'm really not going to create an maintain my own stylesheet. If the default stylesheet of Mkgmap becomes really outdated and there isn't a good alternative one then I'll cancel this service.

Is there somewhere a good alternative generic Mkgmap stylesheet that is being actively developed?

Hi Lambertus
Did some of the tiles get re-numbered or something?
The country selector seems to miss out some tiles - and add others.
United Kingdom on country selector seems to pick up a bit of Turkey, but not all of England !

It appears there is an error somewhere in the UK country definition of perhaps it was a glitch during this build. I know that some countries haven't been defined well enough (UK and Italy for example). Still haven't looked at it yet. But you can always manually add and remove tiles to the selection.
