OpenStreetMap US

October 29–31, 2020

This virtual conference brought together mappers from all over the world for a Mappy Hour, four hours of presentations, and a day of workshops. This was the first iteration of our virtual conference series now known as Mapping USA.

Thank you for helping to make our first virtual conference a success!

This free, virtual event was a celebration of our community and all things OpenStreetMap. Connect 2020 included a Mappy Hour Thursday evening, a half day of talks on Friday, and a day of workshops, birds of a feather sessions and mapathons on Saturday. We hope to make this an annual gathering that enables people from across the country to learn about OpenStreetMap and network with fellow mappers through a combination of curated and community-led dialog.


We had three fun days packed with talks, workshops, hacking, mapping parties and networking all around OpenStreetMap.
