Utilization of 3D Scan Data: “Representation” of Korean Wooden Architectural Heritage

Abstract

This study examines the characteristics of 3D scan data of Korean wooden architectural heritage structures and methods of applying the data from a representation perspective. For the preservation of its unique features, architectural heritage requires accurate representation in terms of investigation, research, and application. The representation of architectural heritage indicates a derivative reflecting the original structure and construction based on the intention of the builder. Thus, the recognition of architectural heritage varies according to the representation methods, which include text, drawings, plans, photos, and 3D scan data, each of which has different advantages and disadvantages. Compared with other models, 3D scan data provide a more accurate representation and carry value as digital data, while minimizing potential intentionality. Three-dimensional scan data can be collated with different types of information, such as building information modeling (BIM), with ease of updating. Therefore, the characteristics of 3D scan data should be identified and applied regarding representation in order to maximize data effectiveness. Three-dimensional scan data can be used most efficiently to create investigative reports representing architectural heritage. By adding the awareness of new technologies, Korean wooden architectural heritage can take advantage of accurate documentation and digital surveys in order to be preserved and recorded sustainably through digital towns and datasets. They can documented and represented through a technology-driven investigative report.
