Kokusai Kogyo Updates Free 'Bois' Service for Rapid Identification of Disaster Survey Aerial Photos

Kokusai Kogyo Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President: Kanau Fujiwara) updated the free version of its disaster information service, 'Bois', in April 2026. The service publishes aerial photos taken during disaster survey operations on its corporate website. This update features a revamped UI designed for intuitive operation, allowing users to more smoothly identify and verify conditions at specific locations from among a massive volume of aerial photos.

Background and Challenges: Responding to Increasingly Severe and Widespread Disasters In recent years, as disasters have become more widespread, the amount of disaster information posted on the site has surged. Consequently, efficiently confirming specific locations from a vast array of images had become a major challenge.

Key Update Features 1. Advanced Background Maps: Supports overlaying with Geospatial Information Authority of Japan (GSI) orthoimages, enhancing the visibility of critical infrastructure like roads and buildings. 2. Thumbnail List View: Displays a large number of photos in a list format, allowing users to move to the shooting location on the map with a single click. 3. Multi-window Mode: Implements a split-screen display for maps and aerial photos to simultaneously check spatial relationships and detailed damage. 4. Optimized Symbol Display: Intuitively visualizes the shooting direction using arrow-shaped icons. 5. Continuous Viewing linked with Map: The map location is highlighted in sync with the switching of displayed images.

About the Free Version of Bois A portion of the BCP support tool 'Bois' was released for free in August 2020. It requires no specialized software or registration, enabling anyone to check the situation in disaster-stricken areas simply by clicking plotted points on a map.

Corporate Paid Service: 'Bois / Disaster Information Service' A platform that automates everything from predicting damage to extracting affected areas during a disaster by pre-registering the locations of bases and suppliers, strongly supporting corporate decision-making.
