Miryang City Accelerates the Establishment of Smart Land Administration Services

Utilizing Drone Orthoimages for Cadastral Boundary Confirmation Surveys
Drones Now Fully Deployed in Surveying Operations

Miryang City in South Gyeongsang Province is accelerating the establishment of a smart land administration service utilizing drones (unmanned aerial vehicles).

The city is going beyond simple aerial photography with drone technology, actively deploying it across the full spectrum of cadastral work that demands a high level of precision, including ▲ cadastral boundary confirmation surveys ▲ land characteristic surveys for officially assessed individual land prices ▲ on-site verification of development charge target areas, thereby dramatically improving work efficiency.

Of particular note is the use of drones in the cadastral boundary confirmation survey process conducted after the completion of large-scale development projects. The city employs drones equipped with high-precision RTK (Real-Time Kinematic) capabilities, which offer accuracy within 3 centimeters, to view the entire project site’s boundaries and facility layouts from above at a glance.

This enables real-time verification of both the actual construction status and the results of the confirmation survey, increasing the accuracy of cadastral records and proactively preventing future boundary disputes.

Drones are also proving highly effective in surveying land characteristics in remote mountainous areas that are difficult to access. Previously, there were limitations for officials to check these sites in person, but now, by overlaying orthoimages and 3D images captured by drones with cadastral maps for monitoring, it has become possible to accurately assess land characteristics without on-site visits.

To enhance expertise and reduce costs, Miryang City officials themselves are obtaining drone operator licenses and conducting field work directly. By having staff members with on-site expertise operate the drones and analyze the data themselves, the city is improving the credibility of its administration and achieving cost savings by reducing reliance on external service providers.

Ju Hyunjung, head of the Civil Complaints and Cadastral Division, stated, "Drones are no longer just tools for simple filming but are now core equipment that determines the precision of cadastral administration," adding, "We will continue to provide transparent and fair land administration services that citizens can trust through data-driven spatial analysis."
