Official street directory Update August 2023
This directory lists all streets, paths, alleys, squares and named districts that are used as street names for addresses. After the update, street axes will be extracted from the Topographic Landscape Model (TLM) in all of Switzerland.
From the end of August, the Official street directory will incorporate the geometry of the street axes from the Topographic Landscape Model (TLM) in all of Switzerland. This change will result in roundabouts, squares, named areas and unnamed roads being treated uniformly throughout Switzerland. In addition, the technical designations of cantonal and national roads are transferred from the TLM to the Official street directory.
