Project description
Goal
To improve the map quality in Estonia, we propose to make data improvements by sharing challenges that can help fix data errors.
When appropriate, our team will also work on these challenges. If a challenge is more suitable to be solved without organised help, we will leave it for local users interested in completing the tasks. Challenges like this will be indicated as such in the overview below.
Additionally, we conduct edits based on map feedback.
How to participate
Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the extended documentation for using MR. Note that sometimes additional instructions are provided within the challenges.
Here is the current set of challenges.
Challenges
Active challenges
Identify and add if needed, one or more missing ways.
Estonia - Fix Spiky Buildings We’ve identified buildings on OpenStreetMap (OSM) with oddly sharp angles. Most building corners are close to 90 degrees, but this challenge focuses on buildings where angles are less than 15 degrees. While some might be real, many are likely incorrect data.

Fix Incorrect Highway Junctions
Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped.
Identify and fix, if needed, cases where a way with tag highway=* intersects with a building.
Identify and fix, if needed, situations where a water feature intersects with a building.
Ways with tag highway= must be connected to the rest of the road network to ensure its continuity, e.g. for route planning. When such a way is not connected to another way with tag highway=, an error is logged.
The area=yes tag is required for some closed ways when used to define a polygon. For closed ways with other tags, there is an assumption that the way defines an area. In some circumstances, a closed way may define both a closed polyline and an area. When tag area=yes is used, it is expected that one of the necessary accompanying tags is also found.
In general, roads intended for vehicles should be built to maintain proper angles which ensure maneuvers and fluent traffic. Extreme, too sharp angles applied to a way may indicate errors in the road geometry.
The necessary edits will be made to fix cases where the tag on a way indicates that the object is a polygon feature, but the way does not meet the definition of a closed way because it is self-intersecting, or ways in a relation with the same role form a self-intersecting polygon
Identify and fix cases where the bridge or tunnel has an incorrect tag.
Identify and fix cases where highways intersect without a common node.
Edits based on map feedback
Click to expand.
We make improvements to OSM based on user feedback submitted for the TomTom map after comparing and ensuring that it is also valid for OSM. 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 - Realigning ferry lines - Adding ferry terminals These are incidental edits spread over time starting July, 17 2023. We follow local guidelines and, if needed, consult with the community before making an update.Geographical scope
Data improvements will be made across the whole country.
Announcements
TomTom organised editing
We will follow the Organised Editing Guidelines for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our Organised Editing page, including a list of our editors.
How to find TomTom's edits
All edits made by our team receive the hashtag #tomtom. 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.
Sources for editing
For some OSM map edits TomTom editors will use proprietary sources for support. These will typically be in situations where there is not sufficient evidence using the available sources in OSM editors themselves. The proprietary sources will be ground-level imagery and GPS traces, both collected by TomTom's mobile mapping vans. On occasion, we will also use sources collected from a field survey by one of TomTom's sourcing specialists who have visited the location and collected data to support the required map updates.
