I'll host a map-a-thon on Kulturarvsdagen with the aim to complete Gamla stan. We meetup here at 09.00. After mapping we meet up at Wikimedia Sveriges office to upload our tracks and have some fika. I will also demo how to transfer images from Mapillary to Wikimedia Commons. This especially because the photo contest Wiki Loves Monuments is happening at the same time and photos may be reused.
