About two months ago the project Code for Germany has started with the project Code for Berlin being part of it. Code for Germany is organized by the Open Knowledge Foundation and aims at initiating local groups in all over Germany, that meet on a regular basis to work on open data apps and visualizations for citizens.
I am one of the organizers of the Berlin group. We meet every Monday at 7 at Wikimedia (Tempelhofer Ufer 23/24, 10963 Berlin) and work on different projects, one of them is Bürger baut Stadt. Everyone who is interested, is always welcome to join.
Together with Joanna Dauner I participated in the idea competition Stadt Land <Code>. One of our ideas – a platform, where citizens can find information about urban planning projects in their districts – was chosen by the jury and we got funding for the implementation. We presented the project during the re:publica 13.
Used technologies were: Python Django, WordPress, TileMill, Leaflet.js, Twitter Bootstrap
Berlin has quite a lot of lakes with bathing spots, but especially during summer time it is hard to find the one nearest by where the water is also of good quality. Together with Designer Marlene Kettner I created a map to get a quick overview using an open dataset that is updated once a week by the city.
Used technologies: leaflet.js, maperative
During my studies at the Hasso-Plattner-Institute I also took part in the project Bundesst@ts. The website combines open data from different sources and visualizes the result for the user. For that we focused on datasets concerning education policy of the different federal states in Germany in order to compare them.
