Belgium | Data Improvements #161

Project description

Goal

To improve the map quality in Belgium, we propose to make data improvements by sharing challenges that can help fix data errors, improve the road network and add features such as water features.

When appropriate, our team will also work on these challenges. If a challenge is more suitable to be solved without organised help, we will leave it for local users interested in completing the tasks. Challenges like this will be indicated as such in the overview below.

Additionally, we conduct edits based on map feedback.

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 take a look at the OSM wiki page containing Conventions for Belgium.

Here is the current set of challenges.

Challenges

Active challenges

Identify and fix, if needed, situations where a building intersects with another building on the same level.

Identify and fix, if needed, cases where a way with tag highway=* intersects with a building.

Identify and fix if needed, cases where highway junctions are incorrectly or imprecisely mapped.

Identify and add if needed, one or more missing ways.

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.

Identify and add, if needed, the missing water feature.

The goal of this challenge is to identify and add missing surface tags on motorways and motorway links as they represent high speed roads, and it is desirable to accurately tag the surface for these highways.

Identify and fix if needed, cases where the way's tag indicates that it is a polygon, but one of the following scenarios occur:

1) the way is self intersecting i.e. it crosses itself. 2) ways with the same role in a relation form a self-intersecting polygon.

Use available resources and local knowledge to identify and fix if needed, cases where an area with a multipolygon relation is actually a simple polygon. In some exceptional cases, the area can be a part of a different multipolygon relation.

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 March 13, 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 Talk-be mailing list:

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 receive the hashtag #tomtom. Edits based on user feedback additionally have the hashtag #tt_mapfeedback.

tt is a hashtag that has been used for TomTom’s edits in the past.

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:

The 'Sources for editing' section updated with the below information-

  1. Removed Maxar Premium Imagery from the list as it's not available anymore in OSM
  2. Added a description of proprietary sources to support editing
