Project description

Goal

To improve the map quality in Mexico, 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.

More Information about the Challenges

Active Challenges - [Mexico - Fix Spiky Buildings](https://maproulette.org/browse/challenges/45168) Examine the set of potentially erroneous buildings that we’ve identified. Visit the locations on the map and assess whether the building shapes seem inaccurate. - [Mexico - Fix Building and Highway Intersect (March 2023)](https://maproulette.org/admin/project/45202/challenge/38543) Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. The fix may be either to correct the building footprint or to correct the route of the highway. Use appropriate available sources to decide on the best action to resolve the conflict. - [Mexico - Connect Isolated Highways](https://maproulette.org/browse/challenges/39321) 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.
Inactive Challenges - [Mexico - Fix Inconsistent Highway Intersections](https://maproulette.org/browse/challenges/39744) This challenge focuses on issues with road geometry, specifically where two roads intersect without a common node. TomTom has utilised a modified version of the Osmose check ‘1250 – objects intersection,’ excluding certain situations like pedestrian paths from the scope. The goal of this challenge is to identify and resolve cases where highways intersect without a common node. - [Mexico - Fix Building and Water Intersections](https://maproulette.org/browse/challenges/40072) We generate the leads after a spatial comparison of water features and buildings available in OSM. The objective is to identify and fix, if needed, situations where a water feature intersects with a building. - [Mexico - Fix Intersecting Buildings](https://maproulette.org/browse/challenges/41429) We generate the leads after a spatial comparison of buildings available in OSM. The Objective is to identify and fix, if needed, situations where a building intersects with another building at the same layer. - [Mexico - Fix Incorrect Junctions on Roundabouts](https://maproulette.org/browse/challenges/42327) : We’ve developed new checks aimed at identifying and correcting cases where two or more highways are connected to the same node on a roundabout. According to the [[OSM wiki documentation](https://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout#:~:text=of%20that%20routes.-,Connecting%20ways,-Connect%20the%20approaching)](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. Why is this important? Fixing such situations will enable routing applications that rely on OSM data to correctly recognise the situation, providing improved guidance when entering or exiting a roundabout. The Leads were detected based on a query of OSM data. We compared the number of highways entering and exiting a roundabout to find situations with a high number of highways or a low number of highways that are part of junction=roundabout or junction=circular. We excluded pedestrian paths, cycleways and roads that are located on different levels (bridges, tunnels). - [Mexico - Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/42333): We’ve identified these tasks through a spatial comparison of buildings in OSM. The goal is to detect and address situations where a building intersects with another building at the same layer. - [Mexico - Add Highways](https://maproulette.org/browse/challenges/43040): We conducted a spatial comparison between TomTom’s in-house road centerlines and other internal sources with the OSM road network, identifying locations that may indicate missing driveways, cul-de-sacs, parking lots, and connections to residential blocks. These tasks will require local community review before attempting resolution. -[Mexico - Update deprecated landuse=reservoir tags - Tlaxcala](https://maproulette.org/browse/challenges/43083): By updating deprecated tags, you are making the OpenStreetMap data more consistent and easier to work with for OSM users. This particular challenge helps you update the deprecated tag landuse=reservoir on water reservoirs in Mexico. The [OSM wiki](https://wiki.openstreetmap.org/wiki/Deprecated_features#Deprecated_features) recommends that this tag be replaced by natural=water + water=reservoir. You will find detailed guidelines for how to do this in the left-hand instruction panel of each task. While editing the water bodies in this challenge, you may further improve them by correcting their outline if needed, or remove them if they no longer exist. - [Mexico - Add Highways - Oaxaca (February 2023)](https://maproulette.org/browse/challenges/37597) Data analysis performed by TomTom suggests that there should be a road or track here in OSM, but it is missing. Use the appropriate aerial imagery and/or local knowledge to investigate and add the missing way. - [Add Surface to Highway - January 2023 - Oaxaca](https://maproulette.org/browse/challenges/37484) 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). - [Invalid Lane Tag](https://maproulette.org/browse/challenges/18637) 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/18629) 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/18630) 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/18633) 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/18635) 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/18638) 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/18628) 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/18632) 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/18634) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/18627) 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.

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 highways - Realigning highways - Adding or adjusting bridges, tunnels, layers, or relations - Updating lanes - Updating traffic signs - 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. These are incidental edits spread over time starting June 5th, 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.

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

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.
