The Spaces, Places and Possibilities project explores ways of developing and using integrated models and realistic visualizations to effectively capture and convey potential outcomes of different development strategies and infrastructure decisions to local government and stakeholders. The project employed a community-based participatory approach in Squamish (BC, Canada), and it consisted of three phases: (1) model and scenario development, (2) scenario modelling, and (3) creating tools for communicating model outcomes, namely a “model explorer” and visualizations. Although the project was conducted in Squamish, its participatory approach for developing community planning and engagement tools can be adapted to communities across the world.
