Modern Surveying And Mapping Technology And Liangzhu Ancient City

- Jul 09, 2019-

On July 6, at the 43rd World Heritage Conference held in Azerbaijan, the site of Liangzhu Ancient City was approved for inclusion in the World Heritage List and became China's 55th World Heritage and 37th World Cultural Heritage. In order to cooperate with Liangzhu and make permanent protection, the relevant departments have used the surveying and mapping geographic information technology to construct a real-time monitoring of “Internet of Things + GIS”, a daily inspection mechanism integrating heaven, earth and air, for the heritage of the heritage and the safety of the natural environment. Provides effective protection.


The ruins of Liangzhu Ancient City are excavated by large-scale urban sites, complex water conservancy systems, hierarchical cemeteries (including altars), and jade rituals with beliefs and institutional symbols, revealing the lower reaches of the Yangtze River in the late Neolithic period. In the Taihu Lake region, there has been a regional early country with rice farming as its economic support, obvious social differentiation and a unified belief, showing the status of the Yangtze River Basin in the “diversity” of the origin of Chinese civilization. General Secretary Xi Jinping pointed out: "The Liangzhu site is a sacred place to prove the history of China's 5,000-year civilization. It is a rare and precious treasure. We must protect it."


The site of Liangzhu Ancient City consists of Yaoshan Site, Tanigu High Dam, plain low dam—mountain long levee and four sites of the city site. The declared heritage area is 1433.66 hectares. The planning area is large, the residual elements are large, the distribution range is wide, and the surrounding environment is complex. In the application, protection and research, the monitoring system construction is a new challenge.

"To maintain the value of this heritage and its authenticity and integrity, and to improve the level of site protection and management, it is necessary to innovate a monitoring system that meets the actual needs of Liangzhu Site through surveying and mapping technology."


Zhu Wu, the person in charge of the National Geographic Information Technology Co., Ltd., who is responsible for this task, introduced that through the integration of modern mapping and geographic information technology and heritage protection work, it can better preserve and highlight the rich historical heritage.


According to reports, the real-time monitoring of “Internet of Things + GIS” implemented in the Liangzhu Ancient City Site is to deploy sensors for environmental factors such as groundwater and surface water level, rainfall, regional air temperature and humidity, local soil moisture content and temperature, and to carry out sites and natural environment. Focus on monitoring, combined with GIS technology for big data analysis. For example, the spatial relationship between the surface runoff water level and the surrounding groundwater level is analyzed. The influence of rainfall intensity on the temperature and humidity of different depths of the soil provides an operational example for the management of large-scale sites and the protection of soil sites in humid environments. The daily inspection mechanism of integration of heaven, earth and air is based on mobile technology, GIS technology and remote sensing monitoring technology. The “monitoring cloud” is developed. The large-scale geographic data of the heritage site is used as the base map, and all the heritage elements and inspection tasks are superimposed. , the formation of accurate grid monitoring. This makes the all-round monitoring a powerful tool for the protection and management of the Liangzhu ancient city site, and the security of the heritage and the environment are effectively guaranteed.
