The Number of Cars in Berlin

How Many Cars is an interactive map which shows the number of cars in Berlin in April 2019. On the map you can see every single moving car in the city (highlighted in pink) and every parked car (colored blue).

Last year more than 40 volunteers used a custom made map tagging tool to identify all the cars on an aerial image of Berlin. The composite aerial image was captured on the 1st and 6th of April 2019. How Many Cars shows the result of this analysis. At the time of writing the tagging of cars in most of the city center is complete. 

You can access the data itself on the Car Tagging Data page on GitHub.  This repository also includes a number of suggestions for how the data might be used, e.g. for analyzing how much space cars take up, for analyzing informal parking (the number of cars not parked in official parking zones), or the number of parking spaces without parked cars.
