Project description

Goal

We propose to improve the map quality in Greece by sharing challenges that can help fix data errors.

How to participate

While our team will also work on them, we welcome anyone to contribute to this project by participating in its 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

Quality check challenges

Click to expand. - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/28352) 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. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/28358) 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 - [Not connected highway](https://maproulette.org/browse/challenges/28350) 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. - [Spiky buildings](https://maproulette.org/browse/challenges/28354) Buildings with extremely sharp angles will be identified and corrected if needed. - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/28346) 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. - [Impossible angle in a highway](https://maproulette.org/browse/challenges/28351) 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 Lane Tag](https://maproulette.org/browse/challenges/28355) 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. - [Invalid Turn Restriction](https://maproulette.org/browse/challenges/28353) 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). - [Polygon is not closed](https://maproulette.org/browse/challenges/28347) 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. - [Edge crossing edge](https://maproulette.org/browse/challenges/38452) Identify and fix cases where highways intersect without a common node. - [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/38733) April - [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/39142) May - [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/39433) June - [Buildings and Highways Conflict](https://maproulette.org/browse/challenges/39499) 21st June Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. - [Building and Waters conflicts]( https://maproulette.org/browse/challenges/39173) Identify and fix, if needed, situations where a water feature intersects with a building - [Inconsistent Bridges and Tunnels](https://maproulette.org/browse/challenges/40278) Identify and fix cases where the bridge or tunnel has an incorrect tag. - [Fix Intersecting Buildings](https://maproulette.org/browse/challenges/41018) Identify and fix, if needed, situations where a building intersects with another building at the same layer. - [Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/42088) Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped. - [Fix Incorrect Junctions on Roundabouts](https://maproulette.org/browse/challenges/42522) Identify and fix cases where two or more highways are connected to the same node on a roundabout.  - [Fix objects without tags](https://maproulette.org/browse/challenges/44302) Improve the OpenStreetMap data by validating and fixing objects without tags.  - [Fix Spiky Buildings](https://maproulette.org/browse/challenges/44746) Improve the OpenStreetMap data by validating and fixing buildings with suspicious sharp corners. 

Missing Highway Surface

Click to expand. - [Add Surface to Highway](https://maproulette.org/browse/challenges/37506) The goal of this challenge is to identify and add missing surface tags on a road network. We queried OSM for ways with certain highway=* values where the surface tag was missing.

Road network challenges

Click to expand. - [Connect Isolated Highways](https://maproulette.org/browse/challenges/37951) 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. - [Add Missing Highways](https://maproulette.org/browse/challenges/37952) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing. - [Add Highways - Athens](https://maproulette.org/browse/challenges/41170) Identify and add if needed, one or more missing ways.

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 May 25, 2023. We follow local guidelines and, if needed, consult with the community before making an update.

Tasking Manager Projects

Click to expand. - [Create Missing Buildings in Larissa](https://tasks.openstreetmap.us/projects/496) We detected gaps in map (San Bartolomeo Val Cavargna and San Nazzaro Val Cavargna) by visual check of data and comparing them to reference source materials representing reality. Project Objectives: Identify and map roads, buildings and other objects that are currently absent from the OpenStreetMap dataset.

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 or #tomtom.

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.

How to reach out

If you have remarks about a specific edit of ours, please drop a comment in the changeset, and we will do our best to respond thoughtfully. Or, you can also:
