OpenStreetMap node ID
The numeric identifier of a matching OpenStreetMap node, which represents a point with geographic coordinates.
A node is a single coordinate, the simplest of the three kinds of element OpenStreetMap stores. It is the right kind for something mapped as a point rather than an outline.
A plain number with no fixed length, no padding and no segments. It counts separately from ways and relations, so the same number can identify different elements of those three types, which is why the kind is part of the field rather than part of the value.
Where the kind is not known, use OpenStreetMap ID instead.
