A Soft Launch of Geo-Project 1941

On 28th October 2023, Ir Dr. Wallace Lai, Associate Head of LSGI, together with historians, archaeologists and geologist from multiple universities, launched the Soft Opening of the art-tech exhibition for Geo-Project 1941. As an event of the project "Unfolding the Lost WWII Heritage: Promotion of Geo-spatial and Geophysical Technologies", it took place at a Campsite “Camptopia” in Sheung Shui. Led by LSGI, this project involves engagement of various stakeholders, such as collaboration with BU, HKU and CUHK, and support from 5 Bureau/Departments of HKSARG. Moreover, it is funded/sponsored by ITC (Innovation and Technology Commission), RILS (Research Institute for Land and Space), and Camptopia. All parties involved share a common vision: to maximize the publicity on historical interpretation, heritage conservation, STEAM education and exhibitions for the remembrance of the 80th anniversary of WWII in 2025. Representing the start of a series of public engagement activities on the use of geo-spatial and geophysical technologies to promote an integrated art-tech approach, this soft opening attracted over 80 visitors from diverse backgrounds. Attendees ranged from professors, teachers, and war enthusiasts to pupils, with interests spanning across geo-science, history, and archaeology. The event featured various art-tech exhibitions and experiential workshops, including a 4D CAVE that provided an immersive experience, transporting the audience back to the war zone in Hong Kong in 1941. Additionally, there were two archaeological test sites where workshop participants could engage in field archaeological excavation work following geophysical surveys. These exhibitions and workshops demonstrated how technologies can play a crucial role in historical interpretation, archaeological excavations, and forensic investigation. Looking ahead to the coming event in the project until early 2025, we anticipate further collaborations between LSGI and diverse communities.   Project:  Unfolding the lost WWII heritage: promotion of geo-spatial and geophysical technologies Website: https://geo-project1941.com/ PI: Ir Dr. Wallace Lai, Associate Head of LSGI

International Delegation from SISV and LJT Visits LSGI to Explore Collaborations and Programme Accreditations

On October 16, 2023, a delegation from the Singapore Institute of Surveyors and Valuers (SISV) and The Land Surveyors Board Malaysia (LJT) paid a visit to the LSGI, accompanied by representatives from the Hong Kong Institute of Surveyors (HKIS). The 13-member delegation was spearheaded by Mr. Mak Weng Tat, the Land Surveying President from SISV, and Dato' Indera Sr. Ismail bin Harun from LJT.  The delegation's morning was spent at Q-Leak, the underground water mains leak detection training centre of the Water Supplies Department. This centre was designed and supported by LSGI since 2021. Ir Dr Wallace Lai, the Associate Head and Associate Professor of LSGI, provided a demonstration and overview of the collaborations between LSGI and WSD, as well as the training and research conducted at Q-Leak.  In the afternoon, the delegation was warmly welcomed by Prof. Wu Chen, the Head of LSGI at PolyU. He provided them with the latest updates on LSGI programmes and research highlight. Discussions were held regarding collaborations on training and talent nurturing. The delegation expressed a strong need for training in underground utilities survey and management from LSGI.  The visit concluded on a positive note, with all parties expressing enthusiasm for future collaborations. The representatives from SISV and LJT were particularly impressed with the innovative programmes and research conducted at LSGI. They expressed their intent to consider further programme accreditation, which would undoubtedly enhance the value of LSGI’s programmes for both local and international students, especially from Malaysia and Singapore.

PolyU Researchers Advance Smart City Development through Remote Sensing Satellites and Low Earth Orbit Satellites

PolyU and Hong Kong Aerospace Technology Group (HKATG) have signed a Memorandum of Understanding to foster their collaboration in satellite navigation, communication, remote sensing, and payload development in August 2023. Under this collaboration, as the key involving department, LSGI can be benefited from provision of optical remote sensing and radar observation data, as well as access to near-Earth orbit satellite payload space and testing services. A media briefing was arranged on 30 August 2023 to share the latest and future research development under the collaborative framework. Prof. Charles Wong, Associate Dean (Teaching) of FCE and Professor of LSGI, stated that LSGI would utilize the provided resources in multiple researches, like monitoring land use, estimating solar energy potential, and water quality mapping. The partnership can not only reduce the cost of data acquisition significantly, but also enhance the resolution of satellite images which can benefit the research. In addition, Dr. Bing XU, Research Assistant Professor of the Department of Aviation and Civil Engineering (AAE), said that AAE was launching a low Earth orbit cube satellite project for navigation and MeV astronomy. The project will enhance positioning accuracy and safety by transmitting navigation signals from LEO orbit to Earth. The cube satellite is scheduled for launch in May 2025.   Online coverage (on 5 Sept 2023): Ming Pao Daily News  Hong Kong Economic Times   Sing Tao Daily   Headline Daily   Wen Wei Po   Ta Kung Pao   Hong Kong Commercial Daily
