you mean footway area, I assume.
It is still an overlap.

What happens when we add extra conflicting tags to the two footways,
such as surface, name, access, etc?

I guess routers will use the one that give the best route.
But that one might not be rendered on the map, which could be confusing.

However the wiki recommends to keep linear ways for routability.
If highway=footway, area=yes are used I think that in most cases it is
better to map the linear footways where you would actually walk, which
is usually a little inside the area.

Speaking of routability we should also avoid unconnected footway areas
such as https://www.openstreetmap.org/way/180120094
.

Thanks Jeff for the feedback, that’s good to know and I’ll look into it. I 
definitely want to make sure everything is actionable and easily doable. In the 
short term I can go through and remove or mark those and completed.

Re: [Talk-dk] MapRoulette challenges for Denmark

[Jeff Huntington via Talk-dk]

Hi, some feedback from me. I’ve been looking at overlapping ways, and have 
corrected some. A common issue seems to be that highway=* overlaps 
highway=footway, area=yes. Where the highway is also a footway, I have not made 
any changes as I don’t see a problem in a pedestrian area being linked to a 
footway, but where highway is something else, I have separated the two ways. 
I’m wondering whether the tool could/ should be refined to ignore the one case 
of highway=footway overlapping highway=footway, area=yes.
I haven’t tried to use the editing tool, prefering to use JOSM to do the actual 
editing.
