30Cappa - The “Christmas” decree in kilometres

Following the COVID-19 pandemic emergency, in mid-December 2020 the Italian government introducedtravel restrictions during the Christmas holidays. In the implemented policies there was an exception:citizens of a municipality of up to 5,000 citizens can move within an area of 30 kilometers from their respectiveborders. This policy was used again in the following months to manage travel during the pandemic.30Cappa is a data visualization created by three civic hackers to give citizens the opportunity to understandthis policy (”cappa” is the pronunciation of the letter ”k” in Italian and means ”km”). The project consistsof a website where it is possible to receive information on the matter and the cartographic representationof the municipalities that correspond to the exception. The site has reached 350,000 unique visitors in twomonths and there has been a lot of talk about it in the media. This work highlights how the transformationof a policy into a tangible product such as a map created with the open data available, becomes an effectivetool to guide citizens and also to review the policies themselves
