Research on Methods for Recording and Visualising Spatial Information of Rural Landscape Heritage with Point Cloud Technology

Point cloud technology has provided significant opportunities to improve rural landscape heritage conservation. Starting from the protection of the value of rural landscape heritage, the recognition of spatial patterns of rural landscapes as the target, this research explores to how to use point cloud technology to record and visualise spatial information of rural landscapes. Bao Jia Tun ancient village, located in Anshun area of Guizhou Province, was used as a case study. Digital close-range photogrammetry, laser radar technology, and point cloud visualisation technology were combined to collect, process and visualise spatial information of rural landscape heritage at different scales. This digital approach can effectively record and present essential spatial features of rural landscape heritage, which provides basic data for the recognition of spatial patterns. This innovative approach also provides new perspectives and tools for heritage conservation and development.
