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. Registration is required to receive virtual meeting links. Please sign up using the linked forms for each event. Thank you for your participation! Want to hear about all upcoming Mappy Hours and other virtual events from OSM US by email? Sign up on this form.
