Project Description
To improve the map quality in Canada, TomTom will to make data improvements in multiple ways. One method is through sharing MapRoulette challenges, sharing source material, and other types of activities, including sponsorships, or supporting local chapters.
We will be sharing challenges to capture missing features and fix potential data errors. All challenges available for Canada are listed on this page.
Over time, we will also be making one-off edits if we see that a specific feature or group of features is missing or incorrect. These edits will be incidental and may impact: POIs, address information, land use, buildings, and tag consistency.
How to Participate
Anyone is welcome to contribute to our MapRoulette challenges. Here is the extended documentation for using MapRoulette. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to make use of the resources listed in the OSM wiki section Canada Tagging guidelines while you are editing.
Here is the current set of challenges.
More Information about the Challenges
Active Challenges
### Active Challenges - [Fix Spiky Buildings](mpr.lt/c/45129) Based on the angle, we identified buildings with geometry featuring suspiciously sharp angles. Normally, building walls meet at close to 90-degree angles. This challenge highlights buildings where the angle between two walls at a single point is less than 15 degrees. While not always a problem, we have noticed that many of these small angles are most likely incorrect. - [Canada - Advanced Map Editing: Validate and Fix Water Objects](https://maproulette.org/browse/challenges/48698) To validate and correct polygons and multipolygons, thereby contributing to the improvement of OpenStreetMap's precision and environmental monitoring efforts. - [Canada - Correct Too Short Highways](https://maproulette.org/browse/challenges/48754) This challenge involves addressing short highway segments and junctions, aiming to enhance navigation accuracy, road data analysis, and the overall visual appeal of the map.Inactive Challenges
### Inactive Challenges - [Polygon is not closed](https://maproulette.org/browse/challenges/27529) Features intended to be a polygon should be correctly tagged. When the tag indicates that the object should be a polygon, but the geometry is built out of a NON-closed way, an error is logged. - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/27167) 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. - [Impossible angle in a highway](https://maproulette.org/browse/challenges/27163) 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. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27160) 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 - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/27161) Simple areas are mapped in OSM by creating a closed way and tagging it as an area object rather than a line. Relations of the type multipolygon are used to represent complex areas with holes inside or consisting of multiple disjoint areas. A multipolygon relation can have any number of ways in the role outer (the outline) and any number of ways in the role inner (the holes), and these must form valid rings to build a multipolygon. When a relation of the type multipolygon consists of only one member, which is a simple area, an error is logged. - [Not connected highway](https://maproulette.org/browse/challenges/27159) 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. - [Invalid Turn Restriction](https://maproulette.org/browse/challenges/27164) This check identifies invalid turn restrictions. Invalid turn restrictions occur in a variety of ways, from invalid members to edge geometry issues to not being routable to wrong topology. Relations, ways and nodes in relations as well as turn restrictions are checked. A relation needs to have exactly one way with role 'from' and exactly one way with role 'to'. These ways should be linked together by at least one way with role 'via' OR with exactly one node with role 'via' (no more and no less). - [Invalid Mini-Roundabout](https://maproulette.org/browse/challenges/27168) Mini-roundabouts are a special kind of roundabout with the same rules as other roundabouts, but present as painted circles rather than physical circles. There might also be a low, fully traversable dome or island that vehicles can drive across. Road traffic flows in one direction around a point in the middle, and the traffic in the roundabout has right-of-way. A mini-roundabout is recorded using the tag highway=mini_roundabout. - [Invalid Lane Tag](https://maproulette.org/browse/challenges/27166) The tag lanes=* on ways with tag highway=* indicates the amount of lanes on the road at hand. The value for the lanes tag should be only one of the following numbers: 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10. Any other value is incorrect and should be fixed. - [Spiky buildings](https://maproulette.org/browse/challenges/27165) Buildings with extremely sharp angles will be identified and corrected if needed. - [Add Surface to Highway - January 2023 - Ontario](https://maproulette.org/browse/challenges/37420) Use the appropriate aerial imagery, street level imagery service, and local knowledge to investigate the situation and assign the most appropriate value to the [surface key](https://wiki.openstreetmap.org/wiki/Key:surface). - [Canada - Fix Building & Highway Intersects](https://maproulette.org/browse/challenges/39085) Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. Leads are generated based on a spatial comparison of highways and buildings available in the OSM data. - [Canada - Connect Isolated Highways](https://maproulette.org/browse/challenges/37654) Leads are generated based on analysis of highway classifications and their connection to the rest of the road network, you can Identify and connect if needed cases where the end of the way with tag highway=* is not connected to the rest of the road network. - [Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/43915) This challenge is to evaluate and fix situations where nodes are located near highways but are disconnected. We expect most situations can be resolved by connecting highways, slightly realigning nodes and ways, or in some cases adding the [noexit=yes](https://wiki.openstreetmap.org/wiki/Tag:noexit%3Dyes) tag.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 June 6, 2023. We follow local guidelines and, if needed, consult with the community before making an update.Geographical Scope
Data improvements will be made throughout the whole country. Occasionally, editing challenges may be targeted for specific provinces, metropolitan areas, or map features.
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 which includes a list of our editors.
How to Find TomTom's Edits
All edits made by our team have the hashtag #tt or #tomtom. We will also add the #tt_mapfeedback to the changeset if it is an incidental edit resulting from user feedback.
Changeset Comments
The team will be adding changeset comments that follow OSM changeset guidelines.
Additional Collaborations
We worked with you in December 2021 on fixing issues with duplicated inner polygons.
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.
