Public transport of Zurich (VBZ): 3D input of catenaries with mobile mapping
Until 2018, Zurich public transports (VBZ) handled their information about contact lines with CAD solutions.
Within the scope of a project about renewal and homogenization of these dataset, the entire network (tram and trolleybus) needed to be re-surveyed in 3D and structured in database model in order to allow a future integration in GIS.
