Serbia | Data Improvements #49

Project description

Goal

To improve the map quality in Serbia, 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.

Here is the current set of challenges.

Challenges

Quality check challenges

Click to expand. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/25225) 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 - [Spiky buildings](https://maproulette.org/browse/challenges/25226) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/25218) 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.

Geometry challenges

Click to expand. - [Missing Roads](https://maproulette.org/browse/challenges/25968) Data analysis done by TomTom suggests that there should be a road or track here in OSM, but it is missing.

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 Sept, 4th 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.

Announcements

This project was announced in the Serbia user forum:

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:
