This talk will cover the growing New York City OpenStreetMap community and our efforts at coordinating mapping our cities’ quirks into the OSM data model. New York City (and much of America) has sidewalks that end abruptly, intersections without proper pedestrian control, uncontrolled slip lanes, bike paths that lead into stairways, crossings without curb cuts. Mapping these features helps NYC pedestrians analyze conditions, report and advocate for changes.
