How complete and how well maintained is OpenStreetMap’s data around the world and in different cities? How has it grown over time? Who has been doing the work? What needs more attention? Tom and Eric have been working to answer these questions by visualizing the data behind OpenStreetMap contributions in helpful ways. They’ll present their findings and show the true state of OpenStreetMap’s data and identify areas where growth and improvement can be made moving forward to make OpenStreetMap a better map.
