Closing Ceremony of the Jockey Club Smart City Tree Management Project on 23 Aug 2021
The Jockey Club Smart City Tree Management Project has finally come to the end after three years of implementation, resulting in a smart monitoring system of over 8,000 trees in Hong Kong. In the recent closing ceremony on 23 August 2021, the technology was officially transferred to the Tree Management Office of the Development Bureau.
At the ceremony, PolyU’s Executive Vice President, Dr Miranda Lou, thanked The Hong Kong Jockey Club Charities Trust for their generous support in enabling PolyU to contribute to the sustainable development and tree conservation in Hong Kong. The Under Secretary for Development, Mr Chun-san Liu, JP thanked the project team and expressed that the continuous use of the system can benefit the community in facilitating urban forestry management.
Developed by Prof. Charles Wong and his research team at the Department of Land Surveying and Geo-Informatics (LSGI), the system involves a Smart Sensing Technology and a GIS-based platform to monitor changes in the surrounding environment and to collect relevant tree data. The leaning trends of trees installed with smart sensors were predicted by big data analysis, triggering safety inspections of trees whose tilting angles exceeded certain thresholds. Risks to passersby and surrounding properties can thus be averted.
