I've updated the GWR extracts that are available from http://qa.poole.ch/addresses/ch/ to data from the 20th of March of this year. As the BfS changed how they provide the data last year (that's the reason that this update was delayed), I used to opportunity to improve and simplify how I update the data. I hope this will lead to more frequent updates, at least till the next time the BfS changes everything.
The caveats with respect to the data quality still apply, in particular because of the rather questionable street data for some mainly mountainous municipalities some local knowledge is a good thing to have before using the data.
On a related note, Jonas (loremo) suggested at one point in time that we should include one of the GWR ids with the data for referencing updates/QA. There seem to be two possibilities how we could do that:
- EGID + EDID (Eidgenössischer Gebäudeidentifikator + Eidgenössischer Eingangsidentifikator)
or
- EGAID (Eidgenössischer Gebäudeadressidentifikator)
The former would seem to be more useful as it allows to determine if the entrances belong to the same building. Any comments? Tagging suggestion?
Further because of the changes it would be possible to generate building type and level count information, it is a bit unclear how well this would map to OSM tags, but is somebody is interested we could look in to this.
