Dabeeo, a geospatial information AI technology company, announced that it successfully completed the '1:1000 Topographic Map Enhancement Pilot Project' promoted by the National Geographic Information Institute of the Ministry of Land, Infrastructure, and Transport last June. During the 180-day project period, Dabeeo utilized AI change detection technology to identify changes in buildings, roads, and other features over a 54 km² area encompassing Geumsan County in Chungcheongnam-do Province and Gunwi County in Daegu Metropolitan City.

Although Dabeeo has been conducting urban change detection projects for several years, this project holds more significance than just its successful completion, as it further advanced their technological capabilities. To produce high-density numerical topographic maps, Dabeeo added a process to convert provided aerial images into true orthophotos, thereby enhancing the accuracy of the analysis data through an advanced algorithm. True orthophoto conversion refers to the process of transforming images captured by aircraft into precise orthophotos, correcting distortions caused by terrain and camera tilt to measure the area, height, and location of the terrain more accurately. Dabeeo developed and applied this technology optimized for change detection in this project.

As a result, the change detection model achieved a 90% precision rate in the F1-Score, a metric for evaluating model performance. The project received high praise for accurately analyzing changes such as the emergence, disappearance, and updates of structures within the observed area, including not only buildings and roads but also crosswalks and solar panels on rooftops.

Meanwhile, to achieve near 100% accuracy in the future, Dabeeo plans to organize the types of undetected cases in the current project and incorporate them into future learning models for further advancement. Building on the expertise accumulated from the Daejeon change detection project over the past three years and the current Geumsan/Gunwi area project, Dabeeo intends to expand into new projects. Dabeeo recently secured the Bucheon City change detection project in June and is preparing to commence work.

Park Ju Hum, CEO of Dabeeo, stated, "Based on continuous research and development in AI change detection technology and the insights gained from previous urban change detection projects, we plan to expand our project scope to include more cities and counties, starting with Bucheon City."
