I could not evaluate it either. But then I think if someone wants to enter that 
data in to OSM that is fine.

The fact that someone can specify what a plant species is and I cannot does not 
mean it cannot go in to OSM.


To me this proposal looks like a preparation for an import.


Oh dear. A dirty filthy import. Where would OSM be if they were allowed?
A lot more blank areas on the map. May be not where you are, but in some places 
they have been very usefull.

If you cannot use a tag, don't use it.

But don't ban its use just because you cannot use it.

That's not the goal. The goal is to have an easy way to identify 
buildings that are more likely to require attention in the immediate 
aftermath of an earthquake.



wouldn't it
be better to have a more meaningful tag that allows to have more than a
binary value?
maybe prexifed with seismic_quality in stead of building in order to be
able to extend this in the future to bridges or other critical objects
if some contributors see an interest in it.
I mentioned this on the talk page: I think this can be valuable but it's 
a separate project. Evaluating seismic quality of any structure needs to 
be done by professionals.

Unfortunately the method used in binary. And probably subjective.

A full objective measurement would cost money and they simply don't want to do 
it.

Do you have a method that is in use that gives a more meaningfull value?

existing objects from an old project a few years old can easily be 
converted if this is the only reason to keep the proposed tag

Hello folks,

discussion is tapering off on

The proposal page: 
https://wiki.openstreetmap.org/wiki/Proposed_features/building:soft_storey


Definition: a type of construction where any one floor is 
significantly more flexible (less stiff) than those above and below it


If there are no more objections or comments, I'll prepare for voting 
some time next week. BTW, I'm at FOSDEM tomorrow afternoon in the geo 
devroom, in case you want to discuss in person, too.


Cheers,

stef

Thank-you very much, Stefano: very nice job!

I hope you don't mind: I made some very minor adjustements to the wording, but 
of course you can revert them if you do not agree...

Cheers,

Sergio

[Tagging] Feature Proposal - RFC - building:soft_storey

2019-01-24 Thread Stefano Maffulli

Hello folks,

I put together a proposal page after our conversations on the list[1]. 
There doesn't seem to be a strong opinion in favor or against 
building:soft_storey as a key, and given that the key is already in 
use[2], I suggest we use it.


The proposal page: 
https://wiki.openstreetmap.org/wiki/Proposed_features/building:soft_storey


Definition: a type of construction where any one floor is significantly 
more flexible (less stiff) than those above and below it


Let's continue the discussion on the Talk page.

Thanks,

Stef
