What Is a Local Digital Twin?
A Local Digital Twin (LDT) is a digital representation of a city, region, or community that combines real-time and historical data to simulate, analyze, and improve urban systems.
Local Digital Twins help public authorities make better decisions by integrating technologies such as:
- Artificial Intelligence (AI)
- Internet of Things (IoT)
- Geographic Information Systems (GIS)
- Urban data platforms
- Predictive analytics
- Simulation and modeling tools
These technologies enable cities to test policies, optimize services, improve sustainability, and strengthen resilience before implementing actions in the real world.
Program Purpose
The LDT4SSC initiative aims to accelerate Europe’s digital transformation by creating a scalable ecosystem of interoperable Local Digital Twins.
The program supports the development of AI-driven services and seeks to overcome common barriers to digital innovation, including:
- Limited investment in AI technologies
