Together we'll discover the next great thing in mapping and hacking but please be kind to our network (bandwidth currently unconfirmed). Some of the lightning talks is scheduled on this day as well.

Optional Photo

How about optional pictures to record that you came to Aizuwakamatsu? We will shoot group photos with Tsuruga castle as background at the Saturday morning. This shooting area is an off limit area, we have special permission.

Optional tour

We will be having an optional tour of the Fukushima Prefectural Museum at Sunday 3:45 pm. Let's touch the history and culture of Fukushima.

Breakout sessions

Throughout the three days of State of the Map we will have a number of rooms set aside for breakout sessions (formally know as "Birds of a feather" sessions).

Some of these will be bookable spaces that you can sign up to host whilst there, others are free spaces - an ideal place where small groups would want to work together, coding a new feature of OpenStreetMap software or collaborating on documentation and guides.

Already have some ideas of what to use these spaces for? Find out how to share your ideas with the OpenStreetMap community.

Fancy a bit of sight-seeing? We are hoping to confirm a Tour of Fukushima museum.
