GIS-Based Spatial Reconstruction of Excavated Goryeo Celadons from the Goryeo Palace Site: Based on Gaesong Manwoldae Inter-Korean Joint Excavation Data

Abstract. This study addresses the limited usability of Goryeo celadon data from the Gaeseong Manwoldae Inter-Korean Joint Excavation. The current Digital Archive for the Inter-Korean Joint Excavation of Gaeseong Manwoldae separates artifact attributes from spatial information, hindering integrated analysis of artifact-findspot relationships and spatial distribution. This research utilizes Geographic Information System (GIS) to overcome this fragmentation. The methodology involved creating an Excel Artifact Attribute Table for 1,089 Goryeo celadon sherds with 28 attributes, including production period and technique. High-resolution site drawings were then georeferenced using ArcGIS, and the attribute data was spatially joined to each artifact's precise excavation location using its unique 'registration number' as a key. This process produced the ArcGIS Artifact Spatial Information Map, an integrated dataset linking artifact attributes with their spatial information. In conclusion, this study establishes a new framework for integrated spatial analysis, overcoming the limitations of fragmented data. The findings are expected to enhance the usability of Manwoldae data, contributing to deeper research on the Goryeo royal court.
