Berliner Roof

hi!

the FOSSGIS was in Berlin - well to my question.

In Lübeck and many other cities old buildings have a "Berliner Dach" (http://de.wikipedia.org/wiki/Berliner_Dach).

I think it would be very important to define a generell roof for this.

regards Jan :-)

Add: i see some buildings where the roof is 2 level high !

That part can be expressed with roof:levels = 2

It seems the Berliner Dach doesn't match any S3DB roof shape, though. It might be worthwhile to invent a value for such roofs, but stay as generic as possible. Perhaps it could be described as a flat top roof with additional parameters?

Re: Berliner Roof

Hello Lübeck,
Berliner Dach is a part of my http://wiki.openstreetmap.org/wiki/OSM- … #Subtype_3 which was a basis for creating of S3DB.
See there type 3.0 and 3.1
This shape is very pupular in whole Europe and I think it sohould be added to the S3DB
Please ask Kendzi. I believe he has already been added this shape.

Re: Berliner Roof

Kendzi3d support roof type 3.0. I could add name for it, but in translation table it is currently named as “saltbox”. I would like to know if “berliner“ is only german name for “saltbox” roof or that are different roof types?

I'm currently using that default values:

ridge location (from front) = 20% * bbox.height
front angle = 60 degrees
back angle = 10 degrees

Re: Berliner Roof

Hello Kendzi,
saltbox is more international. Berliner Dach is common german name let´s use international description. I've added a note with information about it for german mappers in the translation table.

Re: Berliner Roof

@Marek
As saltbox on that wiki page you choose that shape:
150px-Roof3_0.jpg

But on wiki page of S3DB as saltbox someone choose that shape:
150px-Roof3_1.jpg

Please make this consistent.

@Tordanik
Some proposal:
roof:ridge:distance = [ distance of ridge from front of building in meters ]
roof:angle:front = [ degrees ]
roof:height:front = [ meters ]
roof:angle:back = [ degrees ]
roof:height:back = [ meters ]
