​​2018 Taya Cave Sliced Cross-Section Layer Modeling Project (Scale 1/50)

Cooperation: Senshu Elementary School, Yokohama City  
Yokohama National University Masashi Morita  Associate Professor
Associate Professor Yuichi Hayakawa, Hokkaido University
Chiaki Oguchi, Associate Professor, Saitama University

The University of Tokyo PhD Takuro Ogura

In 2017, the 6th graders created a model by horizontally layering styrene paper. In 2018, the 6th graders challenged to create a cross-sectional model of a cave, which is stacked in a vertical slice. Associate Prof. Hayakawa of Hokkaido University supplied laser scan data of the whole cave sliced into sections of 60 cm each, and the 6th graders made a sliced cross-sectional model of the whole cave.

This " sliced-section model of the cave" makes possible the clarification of the height and positional relationship within the cave, which had not been clarified before, and provides useful model data for future cave preservation.
