Geostory Advances Digital Map Update Technology with AI-Based Change Detection

Geostory has advanced its digital map update technology by leveraging its proprietary artificial intelligence (AI) change detection technology, which fuses aerial imagery, satellite imagery, and spatial data.

According to Geostory on July 14, the core of its change detection technology lies in the ability to automatically compare and analyze the latest image data and existing spatial information using AI, quickly extracting areas with potential changes. Previously, specialists had to manually interpret all regions; however, by applying AI-based analysis technology, the company now automatically identifies candidate areas for change and minimizes the scope of manual review, dramatically improving data building efficiency.

The company is securing both accuracy and productivity by applying change pattern analysis technology to various geographical features such as roads, buildings, parks, and industrial facilities. In addition, Geostory has established a digital map update system that swiftly reflects change detection results in the map database, efficiently incorporating information such as the opening of new roads, new building constructions, and changes to major facilities. Furthermore, the company ensures accuracy through a data quality verification process and has established a technical foundation to reliably update nationwide map data by utilizing large-scale spatial data processing technology.

A Geostory official stated, "The core of this technology is that we have overcome the limitations of the old method, where humans had to interpret every area one by one, by adopting AI-based automated analysis," adding, "We will continue to enhance both the speed and accuracy of updates, setting the technical standard for the domestic spatial information industry."
