[Asia Economy Reporter Kangwook Cho] The National Geographic Information Institute under the Ministry of Land, Infrastructure and Transport announced on the 29th that it has completed the construction of three-dimensional digital models for approximately 19 million buildings nationwide and will provide them starting from the 30th.

The three-dimensional building models are created by observing building heights from aerial photographs based on two-dimensional building shapes and compiling them into a database. While the existing two-dimensional building models applied a uniform floor height of 3 meters, limiting their use as practical analysis data, the three-dimensional building models ensure accuracy in building heights, thereby enhancing the reliability of analyses.

Utilizing the three-dimensional building models enables various simulations on a virtual national territory. They can be applied in diverse fields such as air traffic control (including drone routes), flood prediction, and landscape analysis.

However, the Institute explained that since complex building shapes and materials are not represented, there may be some limitations in analyses affected by building protrusions, level differences, and roof shapes.

Sagong Hosang, Director of the National Geographic Information Institute, stated, "Although there are still limitations amid growing interest in digital twin national territory, we have efficiently constructed the models at low cost to enable rapid service first. This signifies that consistent nationwide information on building models has been established, and we plan to continuously improve building shapes and other aspects in the future."
