One day in Budapest drawn by cyclists’ GPS track records.

UrbanCyclr ( app allows bikers to track their biking routes in the city. The individual routes are added to an aggregated map of the bikers’ community. 100.000 kilometers of biking routes have been collected from individual bikers since the launch of the app in 2011.

SubMap ( is a unique tool to visualize geographic and time-based data on distorted maps. It has a huge potential in coping with data from a physically distributed network of independent sensors.
