Organised Editing/Activities/TomTom Map Feedback

Rationale

TomTom started making data improvements to OSM through organised editing in 2021. Starting in 2023 TomTom will validate map feedback from end users for potential updates to OSM.

TomTom receives both business to business (B2B) and business to consumer (B2C) users map feedback. When we say map feedback we mean incidental reports of map errors submitted by a person. It originates as direct reports from users via a variety of apps, APIs, or tools. All of the reports flow into the same production projects on the TomTom side.

We then analyze the reports against existing available sources to validate the suggested addition or change to the map.  If we can confirm the report we update the TomTom map content directly and in many countries for specific features we will analyze the validity of the report for OSM map improvement as well.

However, if we cannot find an ODbL compliant source to validate the OSM improvement then we may do one of the following:

1) Share it as a note to the community on the map directly;

2) Reach out to community members in the area to ask for their feedback or suggestions on means to validate;

3) Perform field collection ourselves, or request community support, to confirm the change in the real world. TomTom field collection could then include edits completed during a survey, capturing & uploading GPS traces, or collecting ground truth images to upload into Mapillary.

Here is a list of the types of edits to be made, provided they do not conflict with others’ edits and a local source is available:

  • Highways
    • Adding or correcting highways
    • Adding or correcting link roads
    • Adding or adjusting bridges, tunnels, layers, or relations
    • Adding or updating lanes and related properties
    • Adding or updating traffic signs
    • Adding or updating access barriers
    • Adding or updating turn restrictions
  • Addresses
    • Adding or correcting addresses
    • Updating the position of address nodes, usually when an object has multiple addresses
    • Adding or correcting names of ways
  • POIs (Points of Interest)
    • Adding POIs
    • Correcting POI locations
    • Adding or correcting POI information
    • Resolving POI-land use discrepancies
    • Handling POI closures
  • Land use
    • Adding land use
    • Modifying existing land use extent
  • Buildings
    • Adding buildings
    • Updating building type
    • Adjusting building shape
  • Water
    • Adding or realigning rivers, streams, and lakes
  • Railways
    • Adding railway tracks
    • Realigning railway tracks
    • Adding or adjusting railway infrastructure tags such as bridges, tunnels, level crossings
  • Ferry lines
    • Adding ferry lines

Imports and mechanical edits are out-of-scope for this activity. Should we encounter systemic issues during the course of editing, we will reach out to the community for guidance.

Contact

Please reach out to osm@tomtom.com with any questions.

Community consultation

We contact the community about all organised editing projects using the local mailing lists. In cases where there there is no active local mailing list, we communicate using the preferred communication channel for that community. Examples include OSM Community Forums, Discord, Telegram, Slack, or Facebook.

Hashtag

Current practice is to use the #tomtom hashtag on edits. Edits based on user feedback additionally have the hashtag #tt_mapfeedback.

#tt is a hashtag that has been used for TomTom’s edits in the past.

Timeframe

These are incidental edits spread across the globe starting in February 2023. During the course of 2023 we expect to extend to additional countries.

We plan to continue edits based on map feedback an ongoing basis into the foreseeable future.

Measuring our success

We perform quality checks to ensure that the changesets made by our editors are accurate, add value to the map, and meet community guidelines. For each quality check, a live editor double checks the following elements of the changeset under review:

  • Did the editor follow the instructions in the challenge and task description?
  • Does the completed changeset fit the scope of the project/challenge/task?
  • Did the editor use the correct task status?
  • Did the editor correctly use the appropriate hashtags?
  • Is the edited map data accurate, according to the applicable source material?
  • Does the changeset follow any and all country-specific capturing methods available on the OSM wiki pages?
  • Was there any community feedback, and, if so, was it implemented correctly?
  • Are the changeset comments clear and accurate?

These quality checks are performed in the following cases:

  • 100% of changesets made by new editors are checked until at least 95% of that editor’s changesets pass the quality checks without any issues.
  • 100% of changesets that are part of a new project are checked until at least 95% of that project’s changesets pass the quality checks without any issues.

Training/instructions

New editors are directed to existing OSM training materials, such as the OSM Wiki and the Help panel of the iD editor. Our team also holds regular editing parties where less experienced editors can receive help and guidance from their more experienced peers.

Post-event clean-up

As referenced above, under Measuring Our Success and Performance, we regularly perform quality checks on our changesets. Whenever a quality check uncovers an issue with a changeset, that changeset is returned to the original editor to be reworked. Once the editor resubmits the changeset, a new quality check occurs. This process repeats until the changeset passes the quality check without issues. To ensure that no issues are missed, each changeset that successfully passes its quality check is then passed on to a second reviewer for an additional check.

Results

Results will be shared through the preferred communication channel for the community.
