Warning for "missing node in relation" not comprehensible #9

Open double-a opened 3 years ago

double-a commented 3 years ago

I just wanted to fix some warnings for Germany/Munich S-Bahn and I do not get the underlying issue: The dataset is missing the railway tracks node n91213610 (relation 12193416, "RB 66: München => Tutzing => Kochel") AFAIK the relation collects all lines of the track and individual nodes for stops/platforms. But the referenced node has no such attribute, thus why is this node missing? Sorry for bothering...

The dataset is the data source for the validator, it may be prepared in different ways such as planet.osm.pbf filtering, overpass query or manually edited xml. Missing node stands for a way/relation is referencing a node that is absent in the dataset. The most common case requires extending the bounding box for the network in the list https://docs.google.com/spreadsheets/d/1SEW1-NiNOnA2qDwievcxYV1FOaQl1mb1fdeyqAxHu3k/edit#gid=112805400 (commenting allowed). I'll examine all such errors shortly.
