Project description

Goal

To improve the map quality in France, we propose to make data improvements by sharing challenges, and when appropriate, fixing data errors, and adding or editing certain kinds of geometry.

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. We also strongly encourage you to make use of the information in the OSM wiki category French tagging guidelines while you are editing.

Here is the current set of challenges.

- [Invalid Lane Tag](https://maproulette.org/browse/challenges/27930) 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. - [Not connected highway](https://maproulette.org/browse/challenges/27918) 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. - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/27925) 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/27923) 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. - [Invalid Turn Restriction](https://maproulette.org/browse/challenges/27927) 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/27919) 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. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27912) 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/27926) 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. - [Spiky buildings](https://maproulette.org/browse/challenges/27924) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27929) 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.

- [Isolated Highways - January 2023]( https://maproulette.org/browse/challenges/37399) - [France - Connect Isolated Highways](https://maproulette.org/browse/challenges/37538) Leads are generated based on analysis of road classes and their connection to the rest of the road network. the goal is to connect the hanging roads to the nearest road network based on the available imagery and/or probe sources - [France - Add Highways - Occitanie](https://maproulette.org/browse/challenges/38538) - [France - Add Highways - Provence-Alpes-Côte d'Azur](https://maproulette.org/browse/challenges/38961) - [France - Add Highways](https://maproulette.org/browse/challenges/41023) We spatially compared TomTom's in-house road centerlines with the OSM road network and identified missing way locations. - [France - Fix Building and Highway Intersections](https://maproulette.org/browse/challenges/40716) Leads are generated based on a spatial comparison of highways and buildings available in the OSM data. The goal is to Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. - [France - Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/41728) The objective is to Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped. We improve overall OpenStreetMap (OSM) route network quality by solving real errors in the data. - [France - Duplicated Nodes having same coordinates](https://maproulette.org/browse/challenges/41816) the objective is to identify and fix if needed, cases where duplicated nodes having same location (coordinates) should be merged. It is more regarding highways mostly, but also have tasks for ways in general (parks, buildings). We found the leads based on spatial analysis of OSM data to fetch overlapping nodes. You might be asking why introducing such type of challenge? well, we are trying to support improving the overall OpenStreetMap (OSM) route network quality by solving real errors in the data, by clearly identifying objects junctions for which nodes are used in this case. Ensuring that highway junctions are connected within OSM is crucial for optimised routing. When road elements are disconnected due to duplicated (not merged) nodes, it can degrade the navigation experience for routing applications that rely on OSM data, leading to inefficient directions, delays, and potential navigation errors. - [France - Fix Incorrect Junctions on Roundabouts](https://maproulette.org/browse/challenges/42365) Identify and fix cases where two or more highways are connected to the same node on a roundabout.  - [France - Fix Inconsistent Highway Intersections](https://maproulette.org/browse/challenges/43570) leads were generated by a modified version of Osmose check ‘1250 – objects intersection’ with certain situations, such as those related to pedestrian paths, removed from the scope. Why is this challenge important? It results in the intersection of two elements placed at the same level. If these elements do not share a common node, proper routing may be obstructed. This intersection forms the basis for routing at junctions. According to the [OSM wiki documentation](https://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout#:~:text=of%20that%20routes.-,Connecting%20ways,-Connect%20the%20approaching), highways entering and exiting a roundabout should never connect to the same node on that roundabout. Fixing such situations will allow the routing software that relies on OSM data to correctly recognize the situation and provide improved guidance when entering or exiting a roundabout. - [France - Fix Spiky Buildings](https://maproulette.org/browse/challenges/44784) This collaborative effort requires a review and possible geometry correction, as the challenge identifies buildings with potential issues due to their unusual shape. It is aimed at improving data quality, accuracy, and aesthetics of OpenStreetMap, making it a more valuable resource for a wide range of users and applications.

- [France - Update highway=road Tags](https://maproulette.org/browse/challenges/43376) The objective of this is to replace the vague tag highway=road on a road, with a tag that accurately describes the type of road, you are helping make sure that the road is shown to OpenStreetMap end users. As explained on the [[OSM wiki](https://wiki.openstreetmap.org/wiki/Tag:highway%3Droad)], OSM-based maps and applications may ignore roads with a highway=road tag because this classification is too ambiguous.

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 have the hashtag #tt, #tomtom or #tt_mapfeedback

Sources for editing

Esri World Imagery
Bing Maps Aerial

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.
