I am interested in getting data on when different entities were constructed or become operational. For example, when was a specific road built or opened for traffic? If there is no such direct data, maybe OSM has some historical archive from which I will be able to infer those dates Thanks a lot! asked 28 Feb '22, 08:07  tomermilo |
One Answer:
OSM has historic data but that will only tell you when something has been added to OSM, not when something has been built. As a trivial example, looking at the 2005 archive data would tell you that there wasn't a single building on the planet. Some mappers record information on when something has been built, usually in the "start_date" tag, but you will find this relatively rarely used. There's also http://openhistoricalmap.org/ which, unlike OSM, aims to also record things that have ceased to exist. answered 28 Feb '22, 09:18  Frederik Ramm ♦ Thanks a lot!

In general you should look in Wikidata. OHM has more "older" history than recent roads.
