[Belgium] Reviewing osmlint-osmium and osmlint data issues

[vladaboitsik]

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 Belgium. In total, there were 227 issues detected across 10 types of linters. Our plan is to review all detected issues and fix it in OpenStreetMap. There's a link to our OSM Wiki page.

Timeframe

We plan to start reviewing detected issues by the end of the week, and editing OpenStreetMap data to fix valid issues.

Tools

We will use existing OpenStreetMap editing tools, and using the #mbx_linters_belgium Editor: iD or JOSM Satellite Imagery: Bing, Maxar, Esri Street Level Imagery: Mapillary, Other open sources if available

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 (natallia.zhouner@mapbox.com) or post a comment in a changeset.

One more such example

Also found crossing roads without common point. You can find example here:

Moreover found unconnected roads. To be routable, they should be connected into the road network. You can find example here

@gplv2 thank you!

Our team finished review of all detected issues, that's why for this moment this ticket is closed. If we're going to review one more time, we'll announce it for community first.

I'm a little confused that this issue is closed, but that there were 260 changesets tagged mbx_linters_belgium in May.
