Geodan has assembled all the digital information that is publicly available, and in doing so has constructed a digital copy of the city that can be visited virtually. In this digital twin, the impact of all kinds of processes and future plans can be calculated and visualised using smart models. This enables us to experience in advance what various scenarios will look like and what the consequences of different processes will be. What is the impact of a new apartment block on the local environment? Or of redirecting a road on the throughflow of traffic? This digital twin of the city helps the city’s residents and those with decision-making authority to assess and understand the different processes more easily, and share ideas with each other in a much more dynamic way. But how do you engage children in the city that they live in? How can we encourage them to think together with us about the city of the future? For these younger urban residents, Geodan has developed the game Ecocraft, based on the game environment of Minecraft.
