An integrated smart city platform: sensors and city systems feeding a central data platform that runs the command centre and citizen services.

A smart city platform: traffic cameras, air quality sensors, smart streetlights and water meters send data through an IoT gateway to a city data platform (data lake plus stream processing). The integrated command and control centre (ICCC) shows live dashboards and incidents to city operators. Department systems (traffic police, water board, waste management) exchange data with the platform. Citizens use a city app to report issues and receive alerts, and an open data portal publishes datasets.
