Hi, Frederik is right: > It seems that you somehow managed to drop a node that is referenced by > something.
I would suspect the --drop option of osmfilter to be responsible for this: --drop="natural=wood waterway=drain or waterway=ditch or waterway=stream or leisure=park" Maybe replacing --drop by the --keep option will do the trick: --keep="natural!=wood and waterway!=drain and waterway!=ditch and waterway!=stream and leisure!=park" Furthermore, you could exclude every broken reference by using this option in osmconvert: --drop-broken-refs Regards Markus _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
