collection of cultural map projects
During the Coding Da Vinci Hackathon 2016, I've explored historical maps of Hamburg. This eventually led to the Chronoscope Hamburg, first a google maps-based web application – now mapbox GL – to travel through time and space in the area of Hamburg.
But there is so much more. On this page you can find some other map projects dedicated to urban culture and history.
