The Ministry of Land, Infrastructure and Transport announced on the 25th that it would enforce partial amendments to the "Regulations on Surveying Implementation" and the "Regulations on Land Administration" on the 26th to enhance the accuracy of cadastral surveys for confirming land boundaries and various permits, starting in March 2025.
In cadastral surveys, errors were permitted due to the limitations of paper maps and tape measure-based analog surveys; however, with the introduction of electronic drawings, surveying software, and electronic flat surveying, the precision of surveys has improved.
Accordingly, the Ministry of Land, Infrastructure and Transport plans to reduce the allowable errors in surveys applied to land survey projects implemented since 1910 to improve the accuracy of measurements and protect citizens' property rights. The allowable error will be reduced from the existing 36 cm–180 cm to 24 cm–120 cm.
Additionally, all surveys will be institutionalized to investigate and confirm the surveying history and results of the target land and adjacent lands, deciding the survey results based on past survey results. This aims to systematically manage survey history to increase consistency in subsequent survey results.
Park Geon-su, director of land information policy at the Ministry of Land, Infrastructure and Transport, noted, "This institutional improvement is significant in that it has established a foundation for reducing survey result error and expanding the use of new technologies such as drones and electronic flat surveying to secure the consistency and accuracy of cadastral surveys." He added, "We will continue to improve the cadastral surveying system by gathering diverse opinions going forward."
