Join the Pedestrian Working Group for a Mappy Hour on Wednesday, July 30th from 8 - 9 pm ET. Contribute to a sidewalk mapping project in OpenStreetMap with guidance from Working Group members, and learn all about the schema for pedestrian infrastructure mapping that the group has been developing for over a year. Mappers of all experience levels are welcome, whether you know the difference between kerb=flush and kerb=lowered or you’ve never mapped a sidewalk before.
