Preservation of Archeological Sites Using 3D-Scanning Documentation Case Study: Sri Dalada Maligawa, Kandy, Sri Lanka

A comprehensive 3D-scanning documentation of the Sri Dalada Maligawa, a UNESCO World Heritage Site and pivotal Buddhist pilgrimage center, reveals critical vulnerabilities to environmental threats such as earthquakes and monsoon rains, as well as human-induced risks like terrorist attacks. The study employed Terrestrial-Laser-Scanning (TLS) and Structured-Light-Scanning (SLS) to create high-resolution CAD plans, point cloud visualizations, orthoimages, and virtual walkthroughs, addressing the lack of accurate documentation for this culturally significant temple. This approach not only preserves architectural details but also enables detailed analysis for conservation strategies, leveraging noninvasive digital technologies to safeguard cultural heritage against degradation.
