Hi Gerd,
Yes, would be interesting to know how Garmin solves this problem e.g. in Africa. I don't know how many roundabouts they have which are likely to fall into a mixed area.
Garmin divides tiles at borders, look for example at City Navigator. cGPSmapper can do this too, you define shape of a tile with background object (0x4B), which can be an irregular polygon. I guess this can be implemented in mkgmap too, only would need more processing then with bounding box. -- Best regards, Andrzej
