AI to Catch Errors in Cadastral Maps... 49th Cadastral Seminar to Be Held on the 5th

[Financial News] Research applying advanced technologies to cadastral administration—including managing cadastral map quality with conversational AI and showing land boundaries on site through augmented reality—will be presented at one event.
According to the Ministry of Land, Infrastructure and Transport on the 4th, the seminar will be held in conjunction with the 2026 K-Geo Festa, which runs from the 4th to the 6th at Korea International Exhibition Center (KINTEX). The cadastral seminar is an academic event where officials and experts from central and local governments, academia, the Korea Land and Geospatial InformatiX Corporation (LX), the Spatial Information Industry Association and other organizations in the cadastral and geospatial information fields gather to share research findings and explore ways to improve regulations and use new technologies. Research aimed at solving problems in the field has identified practical policy measures, and the seminar has proposed ways to incorporate new technologies such as drone surveying, satellite positioning and geographic information systems (GIS) into cadastral work.
AI is at the heart of this year’s presentations. Cases will be introduced in which large language models (LLMs) and other technologies are applied to cadastral administration to support evidence-based decisions and improve efficiency in fieldwork. LX’s Daejeon-Sejong-South Chungcheong Regional Headquarters will present a way to manage the quality of continuous cadastral maps using conversational AI, while Daejeon City Hall will present a plan to innovate cadastral administration using generative AI. LX’s Jeonbuk Regional Headquarters will propose introducing machine learning to analyze the status of geospatial data and land use. Further proposals will focus on bringing advanced technology into the field. Seoul City Hall will present ways to improve cadastral surveys using satellite positioning, while LX’s Busan-Ulsan Regional Headquarters will present a service that uses augmented reality to make cadastral boundaries visible.
Fresh perspectives will feature in the newly added private-sector and university-student categories. Whereas the seminar has so far focused on public-sector employees who directly administer the cadastral system, this year it will also consider ideas from university students majoring in cadastral studies. Shinhan University will present proposals to improve the subjects covered in certification exams in the cadastral field, and Cheongju University will present a plan to develop a personalized pedestrian route guidance service.
The Ministry of Land, Infrastructure and Transport introduced an “expert mentoring system” to the seminar for the first time, helping ensure that research projects lead to policies in the field rather than remaining academic proposals. It also plans to actively seek ways to apply the presented projects to actual work.
The need for new technology in the cadastral field stems from outdated cadastral maps. Paper cadastral maps created during the Japanese colonial period often do not match actual land boundaries or areas. About 5.54 million of the 37.43 million parcels nationwide—approximately 15%—are classified as parcels with cadastral discrepancies. The government has been correcting these through its cadastral resurvey project since 2012. As of last year, about 2.1 million parcels had been rectified, putting the project’s progress at around 38%. However, some projections suggest that slow progress in securing funding could push completion beyond the original target of 2030.
Lee Dae-seop, the Ministry of Land, Infrastructure and Transport’s director general for geospatial information policy, said, “Advances in cutting-edge technologies, including artificial intelligence, are creating new opportunities for change in the cadastral and geospatial information fields. I hope this seminar will allow us to share diverse and creative ideas, and that the results will bring about innovative changes to the cadastral system.”
