TomTom has collected a range of live and historical data since 2008, analysing data from a variety of sources including connected devices and its community of users. Additionally, TomTom's "MoMa" vehicles (short for mobile mapping) cover over 3 billion km annually, using both radar and LiDAR cameras to capture 375 million images annually to sense road changes that are then verified and used to update its maps. TomTom pairs this data with input from partnering brands to process around 2 billion map changes on average each month to keep maps current and reflective of existing road conditions. The brand puts out an updated map database commercially on a weekly basis.
