The use of refined digital mapping to protect Potala Palace was recently exhibited at the Heritage Preservation International-Shanghai 2017, China News reported on August 17.

Potala Palace management said the mapping project was launched in June 2016 and it is about to be completed in three months. They stressed the urgency of the project to protect cultural heritage, given that the palace is built on a mountain with a complicated structure. So far, 90 percent of the project has been completed.

Many advanced technologies, including three-dimensional laser scanning and UAV aerial photography, were used to collect precise information on the architectural complex and surrounding areas. The information will help in monitoring and controlling the palace's networks, the Beijing Digsur Science and Technology Company Ltd in charge of the project, disclosed.

Potala Palace, built 1,300 years ago in Lhasa, capital of southwest China's Tibet Autonomous Region, is one of the world cultural heritage sites in the region.
