Traffic axis system City of Zuerich

In the form of linear references, the traffic axis system provides different data sets (so-called events) in relation to the traffic axes. **Purpose**: In various areas of the city administration, the transport axis system is intended to act as a uniform basis for traffic-related spatial data, which are of great interest. The system should be continuously supplemented with further events. The advantage of linear referencing lies in the separation of the geometries and the axis-related events. This separation allows for the best possible timeliness of the data, since the axis geometries are subject to the follow-up process of official surveying.
