The document discusses the plan4business project, which aims to develop a platform to aggregate, integrate, and analyze urban and regional planning data. This will allow users like researchers, planners, and private sector groups to perform complex analyses and visualizations of trends over time and across regions. The platform will offer planning data and tools via an API and web interface. Key challenges are integrating diverse planning datasets and efficiently querying them. The business model involves data providers, curators, clients, and a data broker hosting the portal to generate revenue from on-demand and subscription services.
