Oh, sorry that my mails treated a subject that was already discussed. @Thilo - You are User:Radfahrer on the wiki, aren't you?
Yes, that's me.
You wrote that you could patch this behaviour and I assume that you do that for the maps of Germany that you offer on osm.ardnet . Could you put that patch upstream into mgkmap or are you preprocessing instead?
I'm preprocessing. But I don't like preprocessing, because it is time- consuming and should better be done in mkgmap. Unfortunately the code dealing with the rules is too complex for me to come up with a better idea easily. So what I will do in the future is to patch the *behaviour* of mkgmap with regard to the tags, e.g. removing the code that makes the road_speed dependent on the maxspeed tag. That's quite important for cycle maps, isn't it ;). BTW, I was corrected in that thread: the first rule of the style file that fits gets applied. But that is only valid for way-generating rules. The code for the action rules is different and I don't really understand it. To me it seems that the action rules may get applied multiple times on each item - perhaps that is the reason why it is so slow for some rules? Regards Thilo
