Abstract

This paper focused on the case of Semal Village, the region that will be demolished due to undergoing recent redevelopment in Paju. We experimented utilizing 3D spatial information to capture precise urban morphology of present status before redevelopment and to transform such data into multi-modal experience of the urban archive. We investigated feasible techniques of photogrammetry and hybrid 3D modelling that could render the situated reality of the village communicatively with various medium such as 3D-printed scale model, and augmented reality (AR) contents. Through drone photography, the entire Semal village was captured, and threedimensional data were obtained using photogrammetry. Along with information from on-site surveys, the mesh model was segmented into buildings, terrain, and vegetation for focused work. Each models reconstructed and retextured using images from the on-site surveys. All data were compiled for full-colour 3D printing and assembly. The 3D-printed scale model replicating Semal is on display at the Paju Central Library. Additionally, an AR content was created using the 3D-printed scale model and ethnographic data, aiming to archive and share people's memories, thereby continuously building a sustainable archive of the village.
