[talk-au] [EXTERNAL] Re: Sydney City Tunnels name= vs tunnel:name=

Sat Mar 28 14:41:30 UTC 2020

I want to update community here.

We have seen that we haven't took all cases into consideration since full stops were missing in our regex queries, and we haven't picked up cases where "bridge" or "tunnel" are at the beginning or at the end of the name string.

Updated strings are:
https://overpass-turbo.eu/s/S11	(92 cases)
https://overpass-turbo.eu/s/S18	(817 cases)

We haven't made any diffs between previous 257 bridge names and 817 that we got by new query, so these will be inspected again, since average time is <50 seconds per item in very obvious cases.

Thanks,
Nemanja

Hi,

I can share more details about this one.

We have used following two Overpass queries to manually check each of bridge and tunnel names:
Brigde names: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Foverpass-turbo.eu%2Fs%2FRWR&data=02%7C01%7Cv-nebrac%40microsoft.com%7Ce17fb22ae93246e6092908d7d231b906%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637208983313189552&sdata=BQctgm%2Bexam5yoLnsZ0%2Fe7NCqryNfmZfb%2B4BVjJKTpM%3D&reserved=0
Tunnel names: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Foverpass-turbo.eu%2Fs%2FRYB&data=02%7C01%7Cv-nebrac%40microsoft.com%7Ce17fb22ae93246e6092908d7d231b906%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637208983313189552&sdata=vxhCqmSqHByCR%2Fx3DgL5iBiuzqh7peHJ2sh4Ns8DdvM%3D&reserved=0

We could see that all 257 bridges had the name of the street that contains "bridge" word (so all of these were false positives), but we found and applied ~10 minor fixes here (layer tag was missing, or even there was a bridge polygon with the actual bridge name, but way had no attributes about it).

Regarding tunnels, we could fix 6 ways, and 17 were false positives. However, we could see that some users used tunnel:name tag, but other were using name:tunnel.

I could see, in my country, that all tunnels got names (especially on a highways/motorways), and some users made a change and added tunnel names into the name tag. They've done that because "it is nicer if you see the name". We have to have as unique data as possible, not to adjust because of render. @Warin61, sounds familiar with landuse/landcover? Render needs to be changed, and that is the other story.

I'm at your disposal for any further questions.

Thanks,
Nemanja

Unless the road has a different name (and I think that would be rare) I agree that the road name is the tunnel name. 

In my experience, signs show the tunnel name without any other road name.  Where there are differences of opinion, I think local knowledge is always to be preferred.
