Select For Cities Hackathon – Make Helsinki smarter


Are you up for the challenge? Create your own solution for making Helsinki a smarter city by using the city's and other data sources on INDRA/Minsait's Onesait IoT and Big Data platform. In conjunction with the Select4Cities project, a hackathon is organized in Helsinki and Antwerp. Sign up for the hackathon now, or join the information event in Espoo to learn more about the platform and the challenge.

The aim of the hackathon is to bring together a diverse range of perspectives, from academics to entrepreneurship and professionals to create innovative smart city solutions utilising Big Data and IoT. Participants will compete by developing a prototype using Onesait platform capabilities to improve Antwerp Smart Zone and Helsinki's Jätkäsaari area.

Some examples of possible solutions; new sensors to let the city speak (noise source detectors, crowds), gadgets and public devices for citizen interaction (actuators, sensors) or apps to increase city interactions or any other way to understand the Talk of The Town and improve citizens life.

The developments have to be created on top of INDRA/Minsait's Onesait Platform. You can use the wide selection of tools provided on the platform and the Data Sources loaded for both Antwerp and Helsinki environments. Examples of loaded data include air pollution, traffic flow and maritime traffic data. If you need it, you can upload your own Data Source.
