Errors in the Map Data
- Quality assurance – Exhaustive list of tools for improving map data quality. Includes tools which show potential mapping bugs.
- Notes – Easily add error reports on the OpenStreetMap main website.
The 'tickets' within our trac system are where we track bugs/enhancement ideas in many OSM-related components (the website, and Nominatim, OpenCycleMap, Potlatch, the style of the default map layer) However increasingly components are dealt with separately with issues lists in various github repos. Check the component's wiki page to find the correct place to file a bug if you are unsure.
