Where OSM tags deviate from valid conventions (Osmose QA), by state. Pick a metric:
Counts are Osmose QA issues — deprecated tags (superseded by newer conventions) and incorrect tag/value combinations — aggregated from Osmose's per-region data. Darker = denser misuse. Two big confounders: Osmose analyzer coverage varies by region, and older / more-heavily-mapped areas carry more deprecated tags simply because they were tagged years ago. Per-area normalisation favours small dense regions. Treat this as a cleanup-prioritisation aid, not a quality verdict.
Data: Osmose QA (items 9002 deprecated + 3040 incorrect tag), aggregated by region. Geometry: Natural Earth / US Census TIGER. Built by an FFL workflow on Facetwork (fwh_osm_mapping).
