A drone that can freely fly between buildings, an autonomous vehicle that runs safely to its destination without a driver, and a smart city that is more convenient and safer.
What makes all this possible? The answer lies in three-dimensional spatial information.
The Korean version of the New Deal announced in July 2020
'Digital Twin' was selected as one of the top 10 projects that will be the core.
The digital twin is a twin-like realization of the real space in a virtual space.
It is a technology that forms the basis of a smart city by analyzing and predicting reality through simulation.
Just as you need to build a foundation to build a building, you need 3D spatial information to be the basis to build a digital twin. 3D spatial information is spatial information that expresses the same three-dimensional effect and texture as in the real world.

How far is the use of 3D spatial information possible?
Drones fly between high-rise buildings to rescue isolated people at the disaster site and manage high-rise buildings that are difficult to access. However, drones cannot move without 3D spatial information.
There is more diverse and three-dimensional 3D spatial information such as the height and location of the building, and the distance between buildings, so the drone can fly safely without colliding with the building.
Autonomous vehicles use sensors on the vehicle to determine the surrounding road conditions. However, by using the sensor alone, it is impossible to obtain any environmental information that can be used to refer to the situation or driving at a distance.
When the maps are combined with three-dimensional precision, precisely manufactured in cm, the autonomous vehicle decides on its own intention to drive and plays a role.
Three-dimensional spatial information enables a smart and convenient smart city.
This important 3D spatial information!
The National Geographic Information Institute has been steadily preparing 10D spatial information over the past 3 years.
Through various feasibility studies, research, and demonstration, it has brought about distinct results.
The three-dimensional spatial information of the National Geographic Information Institute connected to the smart city is still evolving.
Like a map needed to find a way, spatial information is a compass for a better tomorrow.
Now, 3D spatial information is designing the future of Korea.
