[OSM-dev] OSM-3D tagging info

[Matthias Uden]

Hi Ander,

the data you have looks great and it certainly would be a huge 
improvement, particularly in the 3D context.

As you've already recognised, the 3D development in OSM is still
in its early stages and tagging schemas are not yet established but 
still lively discussed.
The most extensive proposal for tag-based building and roof modelling
is made here:

http://wiki.openstreetmap.org/wiki/DE:Roof_table (German)
http://wiki.openstreetmap.org/wiki/3D_building

You can also see what kind of different 3D OSM viewers exist so far and 
which tags are processed by them:

At the moment it is still very difficult to manually apply all these 
tags and it is also currently not recommended to do that since there is 
no consensus if this is the right way.
However, it would already be great if you just included basic tags like 
the building height, the general roof type, number of floors etc.

We will discuss and try to push forward this development during our 
workshop in Garching in March 2012.

Best,
Matthias
