3D ARCHIVING OF ARCHITECTURAL HERITAGE IN SHRINKING TOWNS CASE OF YOICHI, HOKKAIDO

This study will focus on creating 3D archives of architectural heritage in Yoichi, Hokkaido. In many rural areas of Japan, population is decreasing, vacant house rate is increasing, and existing architectural heritage has become a victim of demolition. Preserving all historic buildings is impossible, but there is a chance to create 3D archives for heritage buildings before demolition. Until now, it has been common to create 2D data, but with the development of low-cost devices and technology, it has become easier to create 3D data. The 3D architectural archive has been made mainly by architectural students using low-cost devices.
