OpenStreetMap
Some days ago i wrote a script that analyzes the government data of Winterthur (Switzerland) and shows a list of streets an housenumbers and if they are mapped on OSM.
Have a look: http://www.pfadifotos.ch/osm/statistics.php
The overall Status is just 2.2% by now, but i hope this will increase in future.

Is the source for your script available? I have a similar database I haven't processed for Iceland. It might be interesting to render it like that.
It only has street names / postal codes though. Not house numbers.

Nice! Could you also create a list of missing streets in Winterthur (e.g. something like http://svenanders.openstreetmap.de/SV-stat/Switzerland/Zuerich/)???

@mcdmx: I have compiled a list on the wiki page: osm.wiki/Winterthur#Status
the problem is that this file only contains a list of all streets with housenumbers, streets without housenumbers are not in this list... but it seems that the streets with adresses are nearly complete.
@Ævar Arnfjörð Bjarmason: i can publish the code, but it needs some knowledge of php as it is written as a quick hack (especially the import part) and only works with the current format my import file has. but if you are interested.. ;)

Haette auch Interesse. Beschaeftige mich mit dem linken Zuerichseegemeinden.
Moechte mal testen welche Strassen noch fehlen. Hausnummern sind noch nicht erfasst.
Vielleicht kannst Du Deine Scripts irgendwo auf svn.openstreetmap.org raufladen.
Waere toll. Gruss und Dank Dave
