Emergency_access_point & guidepost: Map as one or two nodes?

Hi folks,

I’ve returned from my vacation in the Hohe Tauern in Austria. There, they basically put a sticker on every guidepost which makes the guidepost an emergency access point:

Now the big question is: Do I map it as one node with tourism=information, information=guidepost, highway=emergency_access_point & all secondary data of guidepost and emergency point, or do I create two seperate nodes close to each other, one for the guidepost, and one for the access point?

I’ve read a few threads that are similar, and there is a tendency that most people suggest two nodes, but I never found really compelling reasons for the one or other methods.

Here’s mine: I also had cases where a hiking map was on the same post as the guidepost. In this case, I have a clash of tags - both would be tourism=information, but one information=guidepost, the other information=map. That basically forced me to map two nodes.

Still, I’m curious if anyone has a compelling arument to do it differently? I mean - as far as I understand, I in principle could also for the map/guidpost clash do information=map;guidepost…

As I will do an estimated 100 or so guideposts over the next days and weeks (we did an excessive hiking vacation :slight_smile: ), I’d appreciate some feedback before I have to correct them all later…

Thanks!

I just came across your post, surprised that no one responded to it.

So how did you do that? (one and the same node or two)

There is the basic rule One feature - one OSM element. A guidepost and an emergency access point are two different features so these should be 2 elements in OSM as well, although the latter is physically not more than a sticker on the guidepost pole.

You will surely find such objects mapped as one node with all the tags of both features in the database. This will work as long as the tags don’t clash (as you have noted already) but as soon as this happens you will need 2 nodes anyhow. So in view of a consistant tagging scheme I’d say it is generally better to map such things with 2 nodes.

Well, it was only 15 mins old when you hit it :slight_smile:

I decided to do two nodes, but wanted to get “confirmation” here.

Thanks for pointing me at this wiki article, very helpful - I just finished my first hike mapping and even decided to correct other people mapping this as one node - glad that I did this right!
