In cooperation with Hokkaido University and the University of Tokyo's Centre for Spatial Information Science (CSIS), basic research is being carried out to understand high-resolution spatial information on the spatial shape of caves and their relationship with the terrain, using various digital survey techniques such as drones and laser scanning surveying.

From the high-resolution digital information, we have been aiming to understand information on the thickness of cave floors, walls and ceilings, as well as their precise positional relationship with the topography.

Understanding complex cave geometries that cannot be surveyed by human hands.

​

• Determination of the dimensions of floors, walls and ceilings.

• Understanding the relationship between the terrain on the ground and the cave.

• Prototyping and studying 3D models.
