Iceland | Data Improvements

[salimbaidoun-tomtom]

Project description

Goal

To improve the map quality in Iceland, we propose to make data improvements by sharing challenges that can help fix data errors, and add or edit certain kinds of features or tags.

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.

We will also conduct edits based on map feedback.

Edits based on map feedback

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 August 1st, 2023. We follow local guidelines and, if needed, consult with the community before making an update.

Geometry Challenges

• Iceland - Fix Building and Highway Intersections
  Our team at TomTom has been diligently conducting spatial analysis, and during our analysis of highway and buildings features available in OSM, we discovered instances where buildings might be intersecting with a highway/road. The goal of this challenge is to identify and rectify any such situations, ensuring accurate map and data representation by utilising reliable sources. It’s important to note that, as with any spatial analysis, there might be some false positives. If you come across a task that you believe is not a valid issue based on your knowledge, we kindly request you to mark it as “Not an issue.”

Geographical scope

Data improvements will be made across the whole country.

Announcements

• TomTom Map Feedback was announced on July 18th 2023 in Talk-is Mailing list
• Iceland - Fix Building and Highway Intersections was announced in [Talk-is] mailing list (August 16th 2023)

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

• ESRI World Clarity (Beta)
  

• Bing Maps Aerial
  

• Mapbox Satellite
  

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:

• send a message to the project lead Salim,
• email [email protected] for general questions about TomTom's activities.

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
