Project description
Goal
To improve the map quality in Turkey, 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 resources listed in the OSM wiki section Turkey Roads Tagging and To contribute / Getting involved while you are editing.
Here is the current set of challenges.

- [Not connected highway](https://maproulette.org/browse/challenges/27644) 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/27649) 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/27645) 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/27653) 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 has self-intersection](https://maproulette.org/browse/challenges/27647) 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/27648) 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/27651) - [Fix Spiky Buildings](https://maproulette.org/browse/challenges/45204) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27652) 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. - [Fix Building & Highway intersections](https://maproulette.org/browse/challenges/39268) Identify and fix, if needed, cases where a way with tag highway=* intersects with a building. - [Fix Inconsistent Highway Intersections](https://maproulette.org/browse/challenges/39528) Identify and fix cases where highways intersect without a common node. - [Fix Building and Water Intersections](https://maproulette.org/browse/challenges/41213) Identify and fix, if needed, situations where a water feature intersects with a building. - [Fix Intersecting Buildings](https://maproulette.org/browse/challenges/43993) Identify and fix, if needed, situations where a building intersects with another building at the same layer. - [Updating Junctions and Improving Highway Network](https://maproulette.org/browse/challenges/49000) - [Fix Incorrect Highway Junctions](https://maproulette.org/browse/challenges/49453) Improve the highway network by remodeling junctions, changing dual and simple carriageways, adding or removing connectors and other highways, aligning highway accuracy, and tagging them accordingly.Geometry challenges

- [Isolated Highways](https://maproulette.org/browse/challenges/37407) 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. - [Add Highways](https://maproulette.org/browse/challenges/40701) - [Add Highways - Sept 2024](https://maproulette.org/browse/challenges/49143) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.Edits based on User Feedback
Missing Highway Surface

- [Add Surface to Highway](https://maproulette.org/browse/challenges/38028) 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.Missing Buildings

- [Add Buildings](https://maproulette.org/browse/challenges/39820) Missing buildings were detected after a spatial comparison with TomTom's map database. The tasks in this challenge focus on physical structures such as residential, commercial, and industrial buildings.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 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.
