Hi Thomas It isn't related to AngleChecker. I notice that both these relations have been changed in the last couple of days so maybe they were faulty. The large one is on the boarder with Scandinavia and it is likely that the map extraction download only had part of it and this gives rise to this type of error.

 Hello , I use mkgmap-4921 with patch from Ticker Berkin -Angelchecker-V6. With that i get in Scandinavia following error : Internal Error Failed to render MultiPolygonRelation 1754729 and 304507. Rel. 1754729 is  'Ladoga'-sea with 5 226 Elements. Rel.  304507 is Multipolygon=water, 171 Elements.  I assume the error ist not specific to the patch...and more common..  How to avoid this ?    regards Thomas    _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
