The data got merged. Than it was uploaded to CartoDB which is a fantastic tool
to visualize data. From this point on, it was just a question to shape the data which is great
with Carto DB: Basic things can be done with the help of a wizard, if you want to go deeper you have
the possibility to modify parts of the css file as well as the html file
I think it's really nice to see the noisy and calm places of my routes through Potsdam.
If more data would be generated, a picture of din and silence can be created.
But it's already nice to find a calm route through Potsdam, especially if you're not aware of Potsdam's streets. ;)
