  • Ancient inscriptions in Bagan preserved with RTI technology

Ancient stone inscriptions in Bagan, a World Heritage Site, are being documented and preserved using Reflectance Transformation Imaging (RTI) technology, according to the Department of Archaeology and National Museum (Bagan Branch).
The ancient stone inscriptions in Bagan have been in place for many years and, as a result, have weakened, been exposed to natural weathering, and been damaged by erosion, causing the engraved characters to become unclear. Therefore, a modern technology called the RTI system is being used to capture detailed images.
Since the stone inscriptions are made of natural sandstone, their surfaces can be damaged, and the letters can fade over time due to weather conditions. Therefore, recording them using this technology will be helpful for long-term conservation and research.
It was also reported that, in carrying out the documentation work using RTI technology, the stone inscriptions were first cleaned, then detailed photographs were taken using the RTI system, and finally, the images were processed using RTI Builder software.
Currently, 83 stone inscriptions have been recorded. Recording them using the RTI system can prevent ink stains that may have occurred during the manual copying of stone inscriptions in the past, help preserve more inscriptions and their characters, and allow the written content to be read more clearly.
There are a total of 352 stone inscription plaques in the Bagan region. Researchers and students who wish to study the inscriptions recorded using the RTI system may contact the Department of Archaeology and the National Museum. — ASH/TH
