[Italy] 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 Italy. 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 in the 1st of June.

Tools

We will use existing OpenStreetMap editing tools, we will use #hashtag for the project #mbx_linters_it

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

Team finished reviewing Linters with the great results. The whole amount fixes is 2602.

So, for now this project is finished.

Italy will be reviewed on permanent bases from the end of August. 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.
