What this diagram shows

  • City sensors and department systems feed one data platform
  • Integrated command and control centre watches the whole city
  • Citizens report issues and get alerts through one app

Prompt used

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.
