Gijang County Becomes First in Busan to Introduce '3D Laser Scanner'

Cadastral Resurvey Accuracy Enhanced
1mm Error Margin Minimizes Boundary Disputes

Gijang County (Governor Jung Jongbok) will be the first among the 16 districts and counties of Busan to introduce a state-of-the-art 3D laser scanner to dramatically improve the accuracy of cadastral resurvey projects.

On January 7, Gijang County announced that it would adopt a high-performance 3D laser scanner to enhance the precision of cadastral resurvey projects and to establish a digital administrative system. This move is a proactive measure to accelerate the digital transformation of cadastral administration and to resolve land boundary disputes through scientific means.

The newly introduced 3D scanner is a device that projects hundreds of thousands of laser points per second, creating three-dimensional data of terrain and structures. By reproducing actual sites in virtual space with an error margin of just 1mm, it is expected to resolve boundary disputes between landowners more objectively and precisely.

This equipment (RTC 360-DS) is equipped with Visual Inertial System (VIS) technology, enabling real-time location recognition and automatic data merging even while moving on site. As a result, the work speed is expected to be several times faster than traditional manual surveying methods, and the duration of cadastral resurvey projects will be significantly shortened.

Gijang County will invest 130 million won from the 2026 main budget to introduce the equipment, and expects to save approximately 7.7 million won annually in outsourcing service fees as a result.

Jung Jongbok, Governor of Gijang County, stated, "The introduction of this 3D laser scanner marks an important milestone symbolizing the digital transformation of cadastral administration in Gijang County. We will do our utmost to thoroughly protect residents' property rights and enhance land use value through precise surveying using cutting-edge equipment."
