TomTom is a Dutch multinational developer and creator of location technology and consumer electronics. The company was founded in Amsterdam in 1991.

TomTom has been making edits in OpenStreetMap through Organised Editing since 2021. In 2023, TomTom released its new TomTom Map that uses OSM data.

Contributions

TomTom contributes to OSM in a variety of ways, including supporting events and local OSM communities, educating new editors, hosting meet ups and local mapping events, sharing editing challenges and making edits in the OSM map.

Map Data Improvements

TomTom is making OSM map updates under its data improvements projects created for over 200 countries and contributes to other’s editing efforts by sharing possible issues or missing content via MapRoulette challenges or Tasking Managers.

OSM and TomTom Devices

The Dutch company TomTom manufactures a range of Linux-based satellite navigation hardware, including a car navigation software and several streetmaps. In addition they have ported their software to several PDAs and mobile phones equipped with Bluetooth or built in GPS receivers.

The navigation units do not normally record tracks. However all recent TomTom units run Linux and allow other software to be installed and run, which extend the functionality of the original firmware. Some useful tools (to record tracks, and others) are listed below:

Using OSM maps with TomToms

Successful attempts were made with Navit software, see TomTom on their wiki.

Though TomTom's mapping format is a closely guarded secret, both for copy protection and because if you knew how they stored the maps, they would be giving away a lot of their navigation secrets. As a result there is no software to allow OSM mapping to be converted to the format the TomTom app uses, and unlikely to be any unless TomTom themselves make it.

  • ttMaps enables the display of raster maps (ECW format) for navigation. It can be used with downloaded OSM maps.
  • Another method to display OSM maps on TomTom could be porting Gosmore to OpenTom. (mail)

Tracking Tools

  • Le Web Bazar offers several add-on applications for TomTom units, including:
    • NMEALogger dumps the nmea output from the receiver into a log file on the memory card or internal FLASH memory. New logs can be automatically created when the unit is resumed.
    • Tripmaster is a more complex applet, with compass, GPS position and such. It can log directly to GPX or KML files. However, it is using the corrected (copyrighted) position from the TomTom software as default. Therefore it must be switched to "Real" coordinates for collecting tracks for OSM. As a downside of Tripmaster, the TomTom moving map is moving noticeably slower (sometimes even freezes for a few seconds) and the TomTom often crashes when selecting a new routing target. The recommended configuration settings (reachable by pressing the ][ button at the bottom right) are:
      • Setup: Coordinates "Real" - to get "uncorrected" GPS coordinates, this is important
  • Event Logger can produce GPX tracks. In early versions the produced GPX tracks were corrected by the TomTom's built-in Maps, and hence using them in OSM is not possible. Versions 6.4 and newer can make a GPX of the raw data from the GPS device. Note: The log interval should be something around 1 second and the Event Logger only logs your position every 10 seconds (?), this is enough to map straight streets but you'll not have enough data to map a turn or smaller details. See this page for more Information about installing Event_Logger on TomTom. --Cohort 2 June 2008 (UTC)
  • ttMaps enables the display of raster maps (ECW format) for navigation. While ttMaps can handle tiled maps, it's faster when using a single big image for each map set. Among the features which are most interesting for OSM users and mappers:
    • Track recording, import and export (GPX)
    • NMEA stream recording
    • Pedestrian mode to get smoother GPS coordinates (must be enabled for OSM data collection)
    • Back and forth switching between several sets of maps, at the touch of a button (installing several OSM map sets rendered at different zoom levels, this feature can be used as a slippy map zooming function)
    • Display of the current or of a stored track (great to visually check which parts have already been explored)
    • Route display (GPX)
    • POI management (GPX and OV2 formats), with position averaging function.
    • Switch off the display after a certain time (configurable) of non-use, for increased battery life. --Kaitu 12:32, 13 May 2009 (UTC)

OpenTom

OpenTom was a center of 3rd party open-source development for the TomTom. There were two intentions of this project:

  1. One was to write and document the writing of add-ons for the normal TomTom software.
  2. The other was to write a new software stack from scratch. Currently, there are no maps or navigation facilities.

Using OSM POIs with TomToms

If you are using Linux, you can use osm-ov2 to download OpenStreetMap data from Geofabrik, extract points of interest and convert them to OV2 format for use in TomTom satnavs.

Using Osmosis with GPSBabel is also possible.
