Digital Preservation and Record of War Fortifications - A Case Study of Qiong-Lin Defense Tunnel in Taiwan

The application of digital technology in the preservation of cultural assets is an international common trend. It combines the acquisition and preservation of integrated data which is very practical for the demonstration of various analysis and diversification. In 2017, 19th General Assembly of the International Ruins and Monuments Council Conference held in India states that government have the responsibility to identify, evaluate, record all of heritage sites and raise awareness of their importance. Therefore, digital preservation technology should be made universal in researching digital asset preservation. This project is based on the concept of digitalized conservation technology development. In order to implement the preservation and management of cultural assets, 3D laser scanning and control survey were used to record Taiwan Qiong-Lin civil defense underground tunnel digitally. To achieve the preservation and development of future cultural assets, this project also includes 3D point cloud models for tiled digital topographic map, urban planning, etc.
