[Talk-ro] Mapbox mapping activity
Sergey Beliamei via Talk-ro
In April 2022 our team is going to start a mapping project in Romania. As part of on-going work to improve the quality of OpenStreetMap data, our team is planning to review a subset of the detections to better understand the type of issues, and also fix any valid data issues directly in the OSM. We're concentrating on road mistakes to improve map condition. In Romania
we plan to upload data once a week to see and fix the latest mistakes in mapping after reviewing the 1st iteration.
We would really appreciate your feedback, any questions you have about this
project, as well as local insights that you think will help us better understand the data.
There's a link to our Github ticket to the related issue and a link to our page in OSM Wiki.
Best regards,

Hello from the Mapbox Team!
At the end of April 2022 our team is going to start a mapping project in Romania.
The project was created to review logical errors with OSM road data and fix it where there’s possibility for improving the road network and enough ground truth sources. We’re concentrating on road mistakes to improve map condition.
Our team is planning to review a subset of the detections, which is divided by categories:
Crossing_highways - roads with no common point
Island_highways - roads not connected to road network
Impossible angle - roads with too narrow angles
Mixed layer - connected roads with different layers
Missing role - turn restriction where 1 role is missed
Excessive role - turn restriction where we have more then 3 roles (e.g.two role “to”)
Invalid role - all roles are represented but doesn’t connected
Missing type restriction - all roles are fine but the type of restriction is missed
We’re using the automatic process for getting the detections which is based on osmium and osmLint (link). The data with OSM errors which we’re going to review is located in the github ticket (link) in json files, you can watch them through geojson.io. After that, we will review new errors in Romania on a permanent basis once a week to support the quality of the road network.
In cases of lack of up to date satellite or imagery the team doesn’t make any edits. And always taking care about local sources, which are the most relevant and unique for each country.
On our wiki page and ticket (osm wiki/ticket) there is detailed information about the background, satellite imageries, timeframes, contact mails. Also, for more clear understanding we have osm wiki pages with more detailed info about types of issues, how we get them and how we deal with feedback (link).
We would really appreciate your feedback, any questions you have about this project, as well as local insights that you think will help us better understand the data.

I took a quick look over most of the linter files and as far as I can tell they look good.
The only concern I have is with trails or tracks in the mountains - e.g. this track here: https://www.openstreetmap.org/way/679608185#map=14/45.6544/25.1013 is part of the "island highways" data set.
Now I can't tell if there's an actual forest track there and the track itself _is_ disconnected from any other highway segment (based on the map I would guess it _is_ connected to the larger track to its west).
How do you plan to fix these?
Without an actual survey this type of edit is almost impossible to get right.
Thanks,
Cristi

This specific road(link) won't be fixed because there aren't enough osm sources to fix it. We fix only those roads that are clearly visible on the satellites, if the roads are not visible, we don't fix it.
