Trees are planted and buildings are built in seconds.
Like a super-detailed version of the simulation game SimCity, changing an entire city in just one sitting is possible through a 3D virtual replica called the digital twin.
South Korea's central city of Jeonju in Jeollabuk-do Province is working with LX, a state-run company that uses geographic information, to use this digital twin technology for its urban projects.
One of them is a project to plant 10 million trees in the city based on the results of digital simulations.
"At the moment, this area outside Jeonju City Hall is mostly empty with very few trees.
But it is one of the places where the digital twin technology is being used to create a cyber forest,… simulating how leafy the area could become in the near future."
The city has initiated this project to cool the temperature of the area, as it has been suffering from the heat island effect.
"Through virtual simulations, expected outcomes of planting the trees including the amount of shade and the reduction in fine dust and noise can be known in advance without actually planting the trees."
By using the digital twin to help control the spread of viruses and fight fires, Jeonju expects it to enhance public safety as well.
Another project is virtual travel.
"Being able to reproduce the city and people to immerse in some of the experiences and discovering some of the attractions like the Royal Portrait Museum or many of the Hanok attractions, I think it can bring more people in the future because people fall in love already."
At the event, participants put on virtual reality goggles to enjoy a bird's eye view of Jeonju and play games at the traditional Hanok Village.
"The government plans to invest around 500 billion won by 2022 in projects using twin technology and expects these to create roughly 5,000 jobs."
The government plans to apply the digital twin technology to five other regions this year and extend it to the whole nation as the foundation for its smart city goals.
