Ah, I did not bother. I just checked that extent was for sure big enough to cover my data in UTM. I removed the lines and result looks much better now. It may even be correct but I have to do further investigations later. Thanks a lot for the hint. I should have been thinking about it. -Jukka- _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
