Hi Andrzej, sorry for the late response. Maybe I got you wrong here. My understanding is that cutting with a polygon is a complex task and I think we don't have code for that in mkgmap. On the other hand, without cutting we might already solve the search problem. Was that your idea?

My guess is, that only background polygon is essential. Maybe would be enough to simply discard objects, which are fully outside of background? All this needs some testing. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
