The map types Line Network Maps, City Maps, and Public Transit Maps, as well as maps that are called up as part of a timetable directory service (for example, walking maps) are based on street maps by Navteq. Their use in printed or digital format is permitted for personal use only; no copying or distribution is allowed. Third-party internet sites may use these maps only in the form of a link that leads to the map contained within the VVS site.
