Recently I try to use the code here to retrieve the original osm id by using the internal edge id. But from the results I just found that several edge ids can lead to the same osm id, for example:
EdgeId = 46398, OsmId = 171731488
EdgeId = 46399, OsmId = 171731488
I should have lost some details about how ‘edge’ and ‘osm way’ are related. Could anyone elaborate a little bit on this?
