Title
3D Recording Process of the Underwater Excavation Site in Waters of Sinchang-ri, Jeju
Description
The paper fits in session 2, as focusing on the survey of underwater cultural heritage at Jeju-do in Korea.
The underwater stie of Shinchang-ri, Jeju-do was reported by Haenyeo1
for golden artifacts in 1980s, and,
further survey recovered Chinese celadon printed with ‘河濱遺范’, ‘金玉滿堂’ in 1990s. However, it was not
until 2018 that consistent investigations were begun by the National Research Institute of Maritime Cultural
Heritage. Exploration is to search artifacts exposed on the bottom surface without any dredging, which is
necessary for understanding distribution of artifacts under the surface. With targeting the area which could
include as many artifacts as possible to be dredged, actual excavations were conducted for three seasons from
2019 to 2021. The objective of underwater investigation is to find the area of intensive distribution of artifacts
and understand their contents. Then, how the environment of underwater sites can be documented by areas?
Waters off Shinchang-ri, Jeju-do have relatively fine visibility, comparing to other sites in Korea. Thus, for the
first time, attempts to document the targeted area in the 3D model with pictures, which is assumed to suggest
more accurate timelines and coordinates than plans, were conducted. Recoding process is begun with taking
pictures which is also the starting point of traditional investigation. Accuracy is the most emphasized.
Methashape of Agisoft is used. Not only are topography of underwater but exact coordinates of hundreds of
artifacts identified. Environment limitation for underwater excavation in Western coasts in Korea exists, such as
strong currents and bad visibility. 3D documentation should be consistently tried, however, as one of the most
important things in archaeological excavation is to locate the shipwrecks and artifacts and document them.
