Hi folks,
I periodically generate a map of Ireland from the Geofabrik ireland.osm extract. With warnings enabled, I get the following:
2010/06/13 20:39:27 WARNING (MultiPolygonRelation): ireland.osm: Multipolygon http://www.openstreetmap.org/browse/relation/4611686018427389788 contains errors. 2010/06/13 20:39:27 WARNING (MultiPolygonRelation): ireland.osm: Polygon 4611686018427393761(6P)(4611686018427392539[6P]) carries role inner but lies inside an inner polygon. Potentially its role should be outer.
Clearly there is no such object ID. Can anybody identify where this is going wrong?
Thanks, Dermot
Hi, the multipolygon with id 4611686018427393761 is an artificial polygon created by the --generate-sea=multipolygon option. There is definitely no chance for the multipolygon code to get the original object ID. This must be fixed in generate-sea code. Have fun! WanMil
