Showcase of Smart Monitoring System for Urban Tree Management

Smart Tree Monitoring and Management System, developed by Prof. Charles Wong and his research team at the LSGI, is showcased at the Smart Countryside Exhibition from 20 December 2021 to 19 February 2022 at the Heung Yee Kuk Exhibition Hall. A simulated tree model, leveraging on smart sensing technologies, is set up to demonstrate how the system keeps track of the angles at which trees are tilting to assess the stability of their roots. This exhibition, in alignment with the Government’s objectives on Smart Village Pilot under “Smart City Blue Print for Hong Kong (Blueprint 2.0)”, promotes smart use of the technologies in the villages to bring convenience and benefits to the residents for better living.

LSGI Career Talk 2022

Graduates' careers and development is always one of our biggest concerns as an academic department. LSGI is a unique source of graduates in disciplines of land surveying, geo-information systems and utility surveying. To share the latest career opportunities in our disciplines for existing students, the Career Talk 2022 was successfully held on 7 Jan 2021 at PolyU Campus by LSGI and LSGI Students' Society.   Dr Wei Yeung YAN, deputy programme leader of BSc(Hons) in Land Surveying and Geo-Informatics, welcomed our guest speakers and kicked start the talk with admission information for senior place of our bachelor's progrmame in 2022. Prior to this talk, we also invited the representatives from Survey and Mapping Office of Lands Department to give sharing on career opportunities and path in land surveying at the Government during regular class for students.   In this Career Talk, we invited 4 LSGI alumni working in public sector to share their jobs and career opportunities. Speakers include: Ms Yvonne Cheu, Technical Director, GIS, Innovative Solutions Department, AECOM Ltd.; Ms Lai Mei Yee, Product Manager, Leica Geosystems, Hong Kong; Ms Helen Chan, BIM Manager, China State Construction Engineering (HK) Ltd.; and  Mr Hanson Li, Assistant Technical Manager, Castco Testing Centre Ltd.   Speakers shared their company development and rising demand in private sector in related disciplines and recruitment tips.  Speakers stayed after the talk to have group chat with our students. The alumni speakers also shared their contacts with students for further questions.  Thank you to all speakers for their fruitful sharing to near 100 HD, BSc and MSc students of LSGI.  

LSGI participates in Project Avenger to dig up Wreckage of US Warplane in WWII

Assisted by Ir Dr. Wallace Lai, Associate Head of LSGI, and his research team with latest surveying technologies, an international team of archaeologists and forensics experts, and over 250 volunteers identified an aircraft wreckage field located at some two-hour uphill climbing to the closest access point at Tai Tam Country Park. The wreckage is believed to be a US warplane ‘TBM Avenger’ crashed during WWII in the Operation Gratitude in 16 January 1945. Within the course of 12 days in November 2021, 80 years after the Japanese invasion, the team recorded 600 fragments in the crash site. Widely reported by few media, Dr. Lai’s team made use of CEDD’s air-borne LiDAR data to portrait the terrain model for identifying possible impact site in the wilderness of Tai Tam. Then during the field work, the team also recorded the coordinates with global navigation satellite system (GNSS) in accuracy of 2cm, re-constructed 3D models of the wreckage by close-range photogrammetry and laser scanners, and mapped the underground objects by ground penetrating radar and metal detector. A complete storyline can be found in here. The Project Avenger unfolds the untold and undiscovered HK wartime history in Tai Tam, and Dr. Lai’s team demonstrates how LSGI technologies can be used to enrich the content of wartime history and archaeology.

Study found impact remnants on the Moon that may provide source of water

A study led by the National Space Science Center of Chinese Academy of Sciences and joined by Prof. Wu Bo, Associate Head of LSGI and Director of Research Centre for Deep Space Explorations, has found carbonaceous chondrite remnants of an impactor in a young lunar crater formed within one million years, a first-time discovery of such fragments by in-situ investigation on the far side of the Moon. Scientists suggests that carbonaceous chondrite-like meteorites may provide 10 to 20% of the sources of water to the present Moon. Prof. Wu’s involvement in the research was to use innovative 3D mapping technology to create a detailed 3D topographic model of the 2-m size crater from the lunar surface images acquired by the Yutu-2 rover of Chang’e-4. The 3D morphological characteristic of the crater is critical to judge if the crater was resulted from a meteorite impact or not. The results were published in the scientific journal Nature Astronomy (https://doi.org/10.1038/s41550-021-01530-w).
