Digital preservation of classical gardens at the San Su Shrine

Abstract

Chinese classical gardens, an essential part of World Cultural Heritage, are well exemplified by Xishu Garden as a notable branch of this tradition. This research focuses on the San Su Shrine—a quintessential example of Xishu Garden—and explores the application of digital technologies in the commemorative research and quantitative preservation of these gardens. By integrating terrestrial laser scanning and terrestrial digital photogrammetry, we acquired quantitative data and constructed digital models to innovate upon the methodological approach to garden conservation. The innovation of this study is its analysis of Xishu Garden’s commemorative spaces through both temporal and spatial dimensions. 1) Temporally, this study examines the evolution and stratification of the garden's commemorative elements across various historical periods. 2) Spatially, it explores the interconnectedness of commemorative elements within the garden's buildings, rockery stones, water landscape and plant landscape. This dual-faceted approach yields novel insights and methods for assessing the universal value of the commemorative aspects of Xishu Garden. Moreover, it promotes the application of digital technology in the study and preservation of Xishu and other Chinese classical gardens.
