Joint-LSGI Alumni Association and LGSI hybrid Distinguished Lecture by Emeritus Professor Yong-Qi Chen

To celebrate Global Surveyors’ Day, a Distinguished Lecture jointly organized by the Department of Land Surveying & Geo-Informatics (LSGI) and Alumni Association (LSGIAA) was held on March 21, 2023. The Distinguished Lecture was in hybrid mode with over fifty participants from different parts of the world online or face to face. The name of the Distinguished Lecture is entitled as ‘Development of a Monitoring System for Power Cable Tunnels with Optic Fibre Sensors’ delivered by Emeritus Professor Yong-Qi Chen. The Lecture is a presentation that gives a discussion on the features of a power cable tunnel compared with traffic tunnels, the difficulties with the existing monitoring techniques, fiber optic sensors, and the system development for a real project. It was an honour for Professor Yong-Qi Chen to deliver a Distinguished Lecture at PolyU when he was still in Emeritus status. Professor Yong-Qi Chen first joined the University in January 1994 as the Head of Department of LSGI, and Chair Professor of Land Surveying. He had been both Chair Professor and Department Head for fourteen years until June 2008. With him at the helm, LSGI achieved exponential growth to become a leading academic department in the field of geomatics. At the start of the Distinguished Lecture, Prof. George Liu, Associate Head of LSGI, represented LSGI to introduce and greet the speaker – Emeritus Professor Yong-Qi Chen. At the end of the Distinguished Lecture, Sr Paul Tsui, Chairman of LSGI Alumni Association, presented the souvenir to Prof. Yong-Qi Chen.

LSGI Research Seminar by Prof. Dr.-Ing. Christian Heipke

On 7 Feb 2023, the Department of Land Surveying and Geo-Informatics (LSGI) successfully organized a research seminar. Prof. Dr.-Ing. Christian Heipke from Leibniz Universität Hannover, Departmental Academic Advisor of LSGI, was invited to give a presentation on “Photogrammetric Computer Vision”.

Prof. Heipke is a professor of photogrammetry and remote sensing at Leibniz Universität Hannover, where he currently leads a group of about 25 researchers. His professional interests comprise all aspects of photogrammetry, remote sensing, image understanding, and their GIS computer connection to has authored or co-authored more than 300 scientific papers, more than 70 of which appeared in peer-reviewed international journals. He is the recipient of the Otto von Gruber Award 1992, the most prestigious award for young scientists in photogrammetry and remote sensing, the Frederick J. Doyle Award 2012 for outstanding and sustained qualities in the profession, both offered by ISPRS, and the Photogrammetric (Fairchild) Award 2013 from ASPRS. His talk focuses on geospatial applications of photogrammetric computer vision, dealing with aerial images, digital surface and terrain models, digital orthophotos, digital landscape models, and 3D city models. An overview of current sensor systems for geospatial data acquisition and automatic data processing procedures is given during his talk. A particular focus is laid on methods borrowed from machine learning. After his sharing, audiences showed strong interest in how machine learning could be used in image recognition and classification. Participants discussed with Prof. Heipke on the future opportunities for graduates in related fields. Questions were raised on technical issues too. At the end of the seminar, on behalf of the LSGI and JC STEM Lab of Earth Observations, Prof. Weng presented the souvenirs and certificate of appreciation to Prof. Heipke.

ASTRI Team Visited JC STEM Lab of Earth Observations for Potential Collaborations

The core members from Hong Kong Applied Science and Technology Research Institute (ASTRI) visited the JC STEM Lab of Earth Observations (JC STEM Lab) and discussed with the principal investigator – Prof. Qihao Weng and some major lab members about the potential collaborations on 6th Feb, 2023. ASTRI was founded by the Government of the Hong Kong Special Administrative Region in 2000 with the mission of enhancing Hong Kong’s competitiveness through applied research. Over the years, ASTRI has nurtured a pool of research, I&T talents and received numerous international awards for its pioneering innovations as well as outstanding business and community contributions. ASTRI has recently set up a framework for cultivating the university technology transfer and collaboration ecosystem. Under the initiative, ASTRI will pursue opportunities to apply funding to do joint projects with universities. With the aim of discovering potential collaboration opportunities with our lab, a total of six core members from ASTRI’s University Tech Transfer Committee, led by Ms. Priscilla YEUNG discussed with Prof. Weng and lab members. The project meeting was led by Prof. Qihao Weng, Chair Professor of Geomatics and Artificial Intelligence and Global STEM Scholar at LSGI, and Director of JC STEM Lab at PolyU. Ir Professor Christopher Chao, Vice President (Research and Innovation) of PolyU, Chair Professor of Thermal and Environmental Engineering, attended the meeting and gave an opening speech on behalf of the university. Prof. Wu Chen, Head of LSGI, and Prof. Xiaoli Ding, Director of Research Institute of Land and Space, also attended the meeting. Other participated members included: Dr. Zhiwei Li (Research Assistant Professor), Dr. Cheolhee Yoo (Research Assistant Professor), Dr. Qiming Zheng (Research Assistant Professor), and Dr. Jessie Jia (Postdoc Fellow). Participants introduced their research field and how they can work hand in hand with ASTRI to cultivate a vibrant ecosystem. In the meeting, Prof. Weng introduced the focus areas of the JC STEM Lab with eleven examples of research: (1) Apartment/house vacancy estimation; (2) Building energy efficiency; (3) Nighttime lighting safety; (4) Accident surveillance; (5) Lighting sources discrimination and pollution monitoring; (6) Bird monitoring for biodiversity conservation; (7) Land cover and land use mapping; (8) Vegetation carbon uptake monitoring; (9) Extreme heat waves and vulnerability; (10) Public health concerns constrained by environmental factors; and (11) Urban Flood Hazard Monitoring and risk assessment. The ASTRI members showed sincere interest in the research areas of the JC STEM Lab. Mr. Andy Lam introduced the opportunities for future collaborations. Ms. Priscilla YEUNG explained such collaborations in much detail, e.g., the function that ASTRI plays in the collaborations, the kind of support they can provide, and the expected outcomes, as well as the foci of immediate research collaboration. Other ASTRI members provided additional information related to the collaboration. Through the in-depth discussions between ASTRI’s University Tech Transfer Committee and the JC STEM Lab at PolyU, more collaborations and business opportunities are expected in the near future.
