OSM has long since established itself as the leading global street database. Interactive multi-resolution 3D-globe-streaming technology has been around for quite some time. Yet little effort has been made so far to create a global OSM-based 3D street map. In this talk we will show how OSM, vector tiles and VTS Geospatial can work together to create a global 3D street map based purely on open data and on open-source technology. The crucial steps of data provisioning, 3D map design and visual styling will be elaborated.
