The unexpected context generated by the appearance of the COVID-19 forced the cancellation of the final on-site presentation of the projects of the Barcelona Dades Obertes Challenge Third edition_2020.

Despite the difficulties, the competition has been adapting to these new circumstances by evolving to the Barcelona Dades Obertes Challenge Third edition (Virtual*)_2020 and giving maximum visibility to the finalist projects.

The students, in spite of the confinement, have been able to work telematically with their tutors and present interesting projects made with data from the Open Data BCN portal.

In this unique edition, we consider all the projects finalists just for the fact of participating and as in previous editions, they have been evaluated by the jury of experts being able to see and hear their opinion..

This 'virtual' project presentation ceremony ends with a closing speech by Mr. Màrius Boada, Director of the Municipal Data Office of the Barcelona City Council, announcing the Barcelona Dades Obertes Challenge Fourth edition_2021, congratulating all the contestants and at the same time expressing his desire to make a new edition in a more favorable environment than this year.
