RESEARCH ON THE TRANSFORMATION OF HISTORIC PATTERNS OF CULTURAL LANDSCAPE USING AERIAL PHOTOGRAMMETRY AND GEO-DATABASE: A CASE STUDY OF KULIANG IN FUZHOU, CHINA
Cultural landscapes are the result of the interactions between cultural and natural features over time. Historic research and site investigation are two conventional methods for identifying the transformation of cultural landscapes. Over the past few decades, with the massive development of computer and internet, technologies such as aerial photogrammetry, GPS and GIS provide new approaches for the study of landscape transformation. The aim of this research is to investigate and present the transformation of a cultural landscape using aerial photogrammetry and geo-database. Kuliang in Fuzhou, a former foreigners’ summer resort established by missionaries in 1886, was used as an instrumental case study. This research has identified historical mountain trails by superimposing historical maps and GPS-recorded tracks. Historic sites were found through a comparison of historical photos and low-altitude drone images. Drone-based orthophotos of the sites provide significant evidence for the restoration of the historical buildings. Furthermore, based on the integration of multiple sources of data in a geo-database, this research reveals Kuliang’s landscape patterns and their transformation over time. The conclusion shows that the use of aerial photogrammetry and geo-database can effectively integrate fragmented cultural landscape information, and identify the transformation of cultural landscape patterns, thereby providing significant references for landscape heritage restoration and sustainable development.
