Editorial- Case Study of Digital Twin of a Country: A New Paradigm for Urban Management and Governance.
Abstract:
Today’s urbanization and the increasing complexity of cities demand innovative approaches to urban management and governance. This paper aims to explore the potential of developing a national-scale Digital Twin as a paradigm-shifting tool for urban planning, real-time decision-making, and governance. By integrating this technology with real-time data gathering and predictive analytics, collaboration between government agencies can be streamlined. The Digital Twin empowers stakeholders to simulate urban dynamics, optimize energy usage, and enhance resilience against crises. Through this case study, we investigate the technical, institutional, and ethical challenges of scaling Digital Twin technology from city-level to country-level implementation. The study also addresses critical concerns such as trust, data privacy, access rights, and data security in governance. Finally, the paper outlines a deployment plan for adopting this technology as the backbone of smart nations, emphasizing advancements in institutions like the Survey of India and the Bureau of Indian Standards. The Digital Twin is both a theoretical and applied concept; its practical implementations provide a comprehensive and representative framework, which justifies their inclusion in this work.
Introduction:
Digital Twin is a virtual replica of a physical asset connected via IoT sensors (or similar devices). Data from these sensors is collected and uploaded to the cloud, enabling experts to study real-time information, run analyses, predict anomalies, identify risks, optimize maintenance, enhance security, and innovate solutions—ultimately improving the asset’s lifecycle.
But why is it important? It is obvious that we want to maximize an asset’s lifespan. By analyzing real-time data, we can monitor conditions, detect early warnings, and make informed decisions before issues escalate. This not only extends the asset’s longevity but also reduces downtime, maintenance costs, and unexpected failures.
The concept of digital twins traces back to the 1960s with NASA’s Apollo 13 mission. When the spacecraft encountered critical issues, engineers used physical replicas on Earth to simulate and resolve problems remotely. Though effective, the term “Digital Twin” did not exist yet.
In 2002, Michael Grieves, a professor, formally named the idea “Digital Twin.” His vision was to create virtual copies of physical objects (e.g., cars, machines) that could self-update over time. Initially adopted by the manufacturing industry to refine product designs and predict machine failures, the technology gained momentum around 2010 when companies like General Electric developed digital twins for jet engines and wind turbines. By integrating IoT sensors and cloud data, these twins became “smarter.”
Cities soon followed. Singapore built a digital twin of its entire city to manage floods and traffic. The healthcare industry embraced the technology, creating patient-specific twins to test treatments safely. Today, digital twins are ubiquitous—used in factories, farms, energy grids, and urban planning to predict disasters, conserve energy, and design sustainable cities. In the near future, they may even integrate with virtual worlds like the metaverse, unlocking immersive new possibilities.
Critical Analysis:
Political & Bureaucratic: The deployment of national Digital Twin must be framed as neutral, apolitical tool for ‘optimizing’ governance. Various ministries need to work together, they may be skeptical regarding this technology.
Cost & Funding: Funding being an important concern for the implementation especially for technology, building a Digital Twin for nation costs billions of dollars. Estonia digital governance took over 20 years to build and develop a Twin and cost over a Billion pounds. Initially twin of a small city/village must be build and tested thoroughly. Indian government have already built a twin for a small village and are now studding what could have done better to scale it.
Interoperability: Interoperability might be a technical challenge, reason being not all stakeholders would be working with similar set of tools, on top of that we need to exchange massive amount of information back and forth. As a solution we need to go as open source as possible, which at least meets interoperability. Open formats such as IFCs, CityGML, City.js, etc are specifically designed for city like digital twin.
Data Integration: If we talk about India, in total we have 54 union ministries and 93 departments of India run by the government, and merging siloed data across ministries would be a challenging. For data integration massive hardware infrastructure IoT sensors, network coverage, satellite coverage, AI/ML, blockchain for security, high-capacity servers to process petabyte of data, high end encryption and anti-hacking protocols. Most importantly all the systems and processes must be scalable and tested, Amsterdam city twin struggle to scale due to data complexity.
Learning from Real-World examples: Last mover advantage, earlier nations have tried building national digital twin, but city like Toronto failed and later cancelled due to public backlash on privacy concerns.
Collaboration: Collaboration with Indian tech giants (TCS, Infosys, etc) can be considered reliable for funding and expertise.
Because DTs are domain-dependent and rely on multiple technologies, the idea of DT – taking multiple domains into consideration and proposing with sufficiently detailed output, yet universal model – is a difficult task.
Discussions:
This study shows ethical challenges and clear road map. To get the ball roll, if we want to build a national level digital twin, initially we need to make the scope, requirements clear, ultimately what is the purpose of building a twin must be clear. For example, safety for woman, sanitation, community health issues, additionally- optimizing traffic, urban planning, security, zoning and land use, monitoring infra works, pollution control, flood control, storm drain analysis, energy management, disaster simulation, fire, emergency situation, army requirements, and the list goes on. Making the scope and requirements crystal clear is arguably the most important stage to think on. Once our end goals are set, data gathering will our next challenge. What kind of data is crucial and needs to be collected and what kind of data can be overlooked, will purely rely on the requirements and scope of a twin. For example, if our primary objective is to control air pollution, probably collecting traffic data or air flow data make sense. Another example, if objective is to study and evade flood related issue, collecting traffic data will not be considered appropriate instead, topographic data, city planning, underground system, and similar data feels much more appropriate and logical. Data from one source will not be sufficient; to build a national level twin we will require massive real-world data from multiple sources, to crosscheck, so we can rely on
the data. There should not be one source of truth. Available resources to collect this kind of massive data would be LiDAR, Google Earth Engine, Drones, etc. Real time data can be collected via IoT sensors, traffic sensors, air quality sensors, climate, CCTV monitoring, water consumption, etc. We can also integrate or embed BIM models, as BIM model has each and every minute detail of the facility, we can leverage the same data source. Massive amount of data will be collected by sensors and uploaded on cloud, next big challenge will be data integration and processing. Robust and strong infrastructure is required to handle this kind of data sets.
Simulation, Analysis and visualization, this data collected needs a way to visualize data in this, game engines like Unity, Unreal, etc can be a good choice. As game engines are designed for similar usage. Most integral part of this process will be the maintenance; we live in a dynamic world where things around us constantly evolves as a result the Twin must be updated continuously with real time evolution. This part will play a very important role in the life cycle of the project.
Singapore, a small island nation and one of the world’s most densely populated countries with over 5.7 million residents, has emerged as a global pioneer in leveraging cutting-edge technology to tackle urban challenges. Faced with limited land, rising sea levels, and rapid urbanization, Singapore became the first country to develop a national-scale digital twin—an ambitious virtual replica of its entire city-state. Known as Virtual Singapore, this 3D platform integrates real-time data from sensors, satellites, and AI to simulate scenarios like flood prevention, traffic optimization, and energy efficiency. By turning its constraints into innovation opportunities, Singapore has set a benchmark for how technology can drive
sustainable governance. Today, its digital twin not only guides policy decisions but also inspires nations worldwide to reimagine urban resilience in the age of climate change and smart cities.
There might me emphasis on various use-cases of this technology. Singapore primarily focuses on energy efficiency and flash flooding with its twin. New York is focused on underground infrastructure monitoring. Barcelona for air pollution control. Boston for climate resilience planning. London for carbon emission reduction strategies. Countries like Germany have accepted the challenge of generating Twin for is all 50M+ buildings. Today we’re experiencing Industry 4.0, where nations are getting smarter and adopting
new edge technology to evolve themselves.
Countries like Australia, Austria, Belgium, Canada, Chine, Czechia, Estonia, Finland, France, Germany, Ireland, Japan, Latvia, Liechtenstein, Luxembourg, Netherlands, UK, USA. Poland, Singapore, Switzerland had already created Digital Twin either of their country or city in their country.
Conclusion:
The concept of national level Digital Twin emphasizes on transformative leap in urban management and governance, offering endless possibilities. By integrating real-time data, predictive analytics, and multi stake holder collaboration, this technology empower policymakers to make informed data-based decisions. A national digital twin is not just a technological tool; it is a socio-political framework that must prioritize transparency, public trust, and equitable access to ensure its benefits reach all citizens. As nations worldwide grapple with urbanization, climate change, and resource constraints, the digital twin
emerges as a powerful ally. By embracing these principles, countries can harness the full potential of digital twins to not only optimize urban systems but also redefine the very essence of governance in the 21st century.
In the end, adoption of new technology requires brain storming and implementation requires mental and physical energy. This is a vision of what we can achieve when technology, policy, and humanity converge. The path ahead is complex, but the rewards—a smarter, fairer, and more sustainable world—are worth the effort.
