Where do we plan the new wind farm or transferium? Where can we build one hundred social housings within in our municipality? How do stakeholders assess the environmental quality at different spatial scales? The Maplab can be used to visualize complex planning- and design-issues (using a so-called MapTable) and, as such, provide better insight into which choices to be made. The participants in the Maplab are encouraged to exchange arguments and come up with creative solutions by the MapTable’s visualization and active set-up. In addition, the Maplab is used in serious gaming, such as in the Carbon Game, a game about negotiating alternative climate policies.
