at the moment i am starting to work on OSM again.
I found out that in my city there are no Tags on the buildings(no addr:street or addr:city …) is there a posibillity to e.g. select all buildings in a area(relation) so that i can add at least the city and postal code for all buildings at once?
Edit: I use JSOM on Ubuntu
P.S.I hope thats the right Topic otherwise just move it
In JOSM you can do a find with multiple conditions, so to find buildings without the city on them you can use something like:
Once you have the buildings selected, simply add the tag.
In the United States postal (ZIP) codes are actually based on the mail delivery routes and are not really areas. There are datasets that have attempted to make them into areas and that works for the most part but there are exceptions. I don’t know where you are but if your location has similar issues, then I’d be careful about adding postal codes.
The political and postalcode boundaries are complete inside the OSM database, so there is no need to only add addr:city and addr:street without addr:housenumber to each building in an area where housenumbers are stiull not mapped in OSM data.
So my answer to your question is:
Technically it is possible, but do not add addr: data without any addr: housenumber … because at least in Germany it is useless.
