"Changing Places researchers are developing a slew of tangible and digital platforms dedicated to solving spatial design and urban planning challenges. The tools range from simulations that quantify the impact of disruptive interventions in cities to communicable collaboration applications. We develop and deploy these tools around the world and maintain open-source repositories for the majority of deployments. "CityScope" is a concept for shared, interactive computation for urban planning... The tool demonstrates a new way for agencies to work together and model the relationship between different urban parameters such as land use, mobility, livability, sustainability, and innovation in real-time."
