At this year's PICNIC festival in Amsterdam, Open Data became one of the main topics. The city of Amsterdam has listened to the hacker community and decided to release public data. For the practical use of citizens and visitors.
The Open Data movement shows what hackers and developers can generate from the use of a city's public data. Taking into consideration traffic data, one was able to develop a computer application that provides drivers with a CO2 emissions and parking fee calculator. With the help of this tool, drivers can decide beforehand, if driving into the city will be worthwile or if they'd better switch to public transit.
