[Denmark] Reviewing osmlint-osmium and osmlint data issues
Background
As part of on-going work to improve the quality of OpenStreetMap data, we recently used osmlint-osmium and osmlint for detecting issues related to road network data in Denmark. In total, we are going to review issues in 9 categories.
Our plan is to review all detected issues and fix it in OpenStreetMap. There's a link to the OSM Wiki page.
Timeframe
We are going to start review on this week.
Tools
We will use existing OpenStreetMap editing tools, we will use #hashtag for the project #mbx_linters_denmark
Editor: iD or JOSM
Satellite Imagery: Bing, Maxar, Esri
Street Level Imagery: Mapillary, Other open sources if available
Contact Person
We welcome feedback, suggestions, and insights from local mappers. If you have questions about this work, or a specific edit by our team, please reach out to Natallia ([email protected]) or post a comment in a changeset.
Example
-
Impossible angle and duplicate
-
Roads don't connected

Team finished review with good results - 75 fixed items.
So, for now this project is finished.
We're going to have 2nd iteration in March 2022. Denmark will be reviewed on permanent bases after closing 2nd iteration. Once a week there'll be a upload of data and team will close these issues.
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.
| Issue | Data |
|---|---|
| Crossing Highways | DK_crossinghighways.zip |
| Island Highways | DK_islandhighways.zip |
| Impossible Angle | DK_impossibleangles.zip |
| Impossible Oneways | DK_impossibleoneways.zip |
I would strongly recommend using SDFE aerial imagery as Satellite Imagery for Denmark.
It is by far the best quality, and most frequently updated.
Another useful resource is https://skraafoto.kortforsyningen.dk/ which provides aerial imagery from different angles.
Kind regards,
@elhaard Thank you for your comment! We'll keep it in mind during our work.
