Research direction

Start with the Resolving lintings problems in Canada OSM Wiki page and the linked linter-output ZIP files. Use iD or JOSM with the listed imagery to review the nine categories and verify each finding. Done means confirmed data issues are corrected in OpenStreetMap and reviewed items are accounted for.

Written by the indexing model from the issue text.

Description

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 Canada. 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_canada

Editor: iD or JOSM

Satellite Imagery: Bing, Maxar, Esri

Street Level Imagery: Mapillary, Other open sources if available
