Following the vertical traffic signs, a road marking on the Meyrin and Prévessin sites is now available on GIS Portal. The data is not added to the map by default. It can be displayed either by selecting 'Traffic Signs' (Signalisation routière) from the menu 'Data/Aboveground data' (Données/Données de surface) or searching for 'Traffic Signs' (Signalisation routière). The road marking is visible from scale 1:5000 onwards.
It is possible to extract the data in DWG format using the DWG Extraction Tool available on GIS Portal.
