Sign up The OpenStreetMap US Mappy Hours are virtual hangouts for the U.S. community. User:mvexel started the Mappy Hours in 2013 and continues to host them alongside other participants from OpenStreetMap US. After a hiatus, the Mappy Hours were reintroduced in 2019.

What are the Mappy Hours about?

The Mappy Hours are casual gatherings and a space to meet new people. We often have a presentation and an OSM-related topic of discussion. Conversations tend to be about things like:

  • Mapping and Tagging
  • Imports
  • Local groups and local events
  • The OSM US organization
  • What's happening in the rest of the world
  • Anything you want to discuss!


Virtual Mappy Hours are planned on a regular (mostly monthly) basis. Signing up is now required. Please sign up using the linked forms for each event. Thank you for your participation!
