Just so there is no misunderstanding: even taking address tagged nodes in to account, the addresses / houses ratio is lower and at best not different than in other countries without countrywide access to cadastre-like sources. 3% with nodes, 0.6% without, comparision CH: 18% / 12%. The numbers are from the respective taginfo instances. So the question remains why the information in not being added to the outlines. Simon
