There is no reason for a vector map to have a lower resolution than the
OSM data itself.  But, this is not the point.  The difference to a
bitmap is that a vector image contains descrete objects which someone
could import directly into a database.  So, one could view a vector map
as a database of map objects.

Each .osm file already is a vector map.
