How we use OSM data for news mapping
summary
Washington Post cartography uses OpenStreetMap as a live base layer with building polygons, streets and alleys to produce breaking maps fast. Examples include mapping a Cessna flight path and DC special flight rule that caused a sonic boom, daily front line maps for Ukraine fed by daily shapefile updates from a conflict source, and a flood/dam map showing plant locations and inundation paths. Verification mixes openstreetmap.com with Google Maps and reporter coordinates.
