Feasibility Study on the Application of Surveying Technology for Developing Heritage Site Information Model : A Case study : Wat Chiang Ban ChiangKham District Phayao

Abstract

The Study aims to evaluate the feasibility and effectiveness of modern surveying technologies in heritage site documentation, using Wat Chiang Ban in Phayao Province, Thailand, as a case study. Three data collection methods were compared: traditional field measurement using measuring tapes (control method), terrestrial laser scanning (TLS), and unmanned aerial vehicles (UAVs). The TLS and UAV data were processed using Autodesk Recap and Agisoft Metashape.

The results revealed that TLS provided the highest accuracy with a reliability of 94.734%, followed by UAVs with a reliability of 90.472%, when compared to the baseline data from measuring tapes. The study further analyzed the advantages, limitations, operational time, and costs associated with each method. Findings suggest that TLS and UAVs offer practical and efficient solutions for acquiring accurate 3D spatial data for heritage conservation. This research supports the application of advanced surveying technologies in the development of Heritage Building Information Modeling (H-BIM), which plays a critical role in the restoration, conservation, and cultural tourism promotion of historic sites.
