[OSM-talk] 3D somehow not compatible with our map and editing concepts / capabilities?

[Marco Boeringa]

Martin,

I have now added a type=building relation to group the Pantheon's Simple 
3D features in a logical way. It is this relation: 
http://www.openstreetmap.org/relation/6325840.

I added the "outline" role to the multipolygon representing the 
building's footprint, and added the "part" role to all building:part 
features in the relation. This is how a properly formed Simple 3D 
building should be tagged.

As you can see now on the OpenStreetMap website, whatever part you 
click, you can now navigate "upwards" to the parent type=building 
relation, to see which features are all parts of the building, and then 
move "downwards" to the feature with the "outline" role to get to the 
actual building tags. I hope you agree that navigating the buildings 
individual parts, and finding the actual feature that carries the 
buildings tags (which should always be the closed way or multipolygon 
with the outline role), is now fare easier.

I still wish though that the main OpenStreetMap website's interface 
would stop showing the senseless individual nodes or ways links first 
when you select a feature, and put relation links on top instead. This 
would make it even more obvious that there is a parent building relation 
present. Now, you sometimes need to scroll down considerably, to get to 
the relation links. In my opinion, the hierarchy of nodes/ways/relations 
should be reversed in the display on the website. I have never 
understood the choice for the current display / order, it is just not 
logical for navigation.

Marco
