Abstract:

The aim of this study was to understand the advances in the research into the applications of three-dimensional (3D) digital surveying and information management techniques on garden cultural heritages. In this study, we analyzed Chinese and English literature for applications of 3D digital surveying and information management techniques related to the garden cultural heritage. Then, we assessed the techniques features, application situations, and related cases for 3D digital surveying and information techniques applications on garden cultural heritages from the perspective of 3D digital surveying techniques, such as close-range photogrammetry, 3D laser scanning, and multi-technology integrated surveying, as well as 3D information management techniques, such as the 3D geographic information system and information model. Cultural heritage protection work is crucial. We noted abundant research applications for 3D digital surveying and information techniques focused on culture heritage objects, such as ancient architectural sites, but few was focused on the garden cultural heritage. However, there were sufficient applications to confirm the advantages of such application, and it was inevitable that these methods would become the norm. Regarding 3D digital surveying methods, close-range photogrammetry and 3D laser scanning technologies had their own advantages and disadvantages. An integra-ted surveying method with multiple sensors could overcome the limitation of a single technology and instrument and was an ideal method for acquiring data regarding the garden cultural heritage. With regard to 3D information management methods, the applications of 3D geographic systems and landscape information model were the focus of research on information management for the landscape cultural heritage. Protecting landscape cultural heritages and even the discipline of landscape architecture will help show progress regarding 3D digitization and informatization. It is of great historical and practical significance to collect, process, store data and to manage, maintain, update, and analyze information for the protection, study, and sustainable utilization of garden cultural heritages.

Key words: garden cultural heritage, digital survey, 3D GIS, close-range photogrammetry, 3D laser scanning, landscape information system
