On: Italy bridge: Genoa motorway collapse kills at lea...

[Freak_NL]

I was looking for the site of the bridge on OpenStreetMap, but couldn't find it. It took me a while to realize that someone already took it off the map within an hour of it collapsing.

Impressive (and correct), if a little disconcerting:

https://www.openstreetmap.org/#map=17/44.42585/8.88840

All the access roads have been disabled too.

I removed it as soon as I got the news. First thing is to have the routing software updated and handle the emergency. I live in Genoa ad I work in a logistic company, and I'm an OSM contributor since 2011 :-)

Well played. Despite the tragedy, that must be your finest OSM hour.

The power the OSM tagging system.is capable of astounds me over and over. Looking for benches with backrests in your area? There's a way to encode the locations of those in OSM!

Are you allowed to bring your bike onboard this ferry? Does it have a toilet? All answerable with OSM!

Of course, the downside is a diverse set of opinions on how to tag stuff, but I get the impression OSM editors are aware of the vast public benefits of having an agreed-upon way to tag things.

What I really, really, like is location of all the public toilets. This is precious information while exploring big cities.

You're welcome :-)

I wonder if there's also @Anonymaps on HN...

Googles map with sattelite and traffic updates https://www.google.co.uk/maps/@44.425374,8.8839348,2984m/dat...

It has a quite a good 3d render of the bridge and street level view if you zoom in

[aembleton → Freak_NL]

If you zoom out, it is still there. I guess it might be a cache https://www.openstreetmap.org/#map=16/44.4262/8.8879

[Freak_NL → aembleton]

Lower zoom-levels are cached for a longer period than higher ones for performance reasons.

OpenStreetMap per se is, in the pedantic/correct sense, not the bitmap tiles, but the database used to generate them.

Wikipedia was very quick, too.

The italian entry for the bridge was semiprotected as soon as the news broke, but now I see there's a enwiki standalone entry https://en.wikipedia.org/wiki/Ponte_Morandi
