</div>I think you're overlooking a key strength with the osm database, that<br>
all the map features are integrated, e.g. if a kiosk is mapped to be<br>
three meters to the left of the entrance to the building, and that is<br>
also the ground truth, then you have that fact of their interrelation.<br>
With different datasets from different sources, you lose it.<br>
