LSGI Showcased in GeoConnect Asia 2026

The Department of Land Surveying and Geo-Informatics (LSGI) of The Hong Kong Polytechnic University (PolyU) successfully participated in Geo Connect Asia 2026, held from 31 March to 1 April at the Sands Expo & Convention Centre, Singapore. As one of Asia’s premier geospatial industry events, Geo Connect Asia 2026 brought together global professionals, cutting-edge surveying instruments, and thought‑leading technical presentations. Leveraging this platform, PolyU LSGI joined forces with four Singaporean institutions, including the National University of Singapore, Nanyang Technological University, Singapore Institute of Technology, and Temasek Polytechnic to form “The Learning Lab” joint booth. The LSGI team prominently featured its two flagship undergraduate and postgraduate programmes: Land Surveying and Geo‑informatics and Urban Informatics and Smart City. These programmes integrate surveying technology, spatial data, artificial intelligence, urban planning, and digital twins, offering both academic depth and practical relevance. The booth drew keen interest and inquiries from students and industry practitioners from Singapore, Malaysia, and other neighbouring countries. During the exhibition, Mr. Eric Chua, Senior Parliamentary Secretary for the Ministry of Social and Family Development and also for the Ministry of Law of Singapore, visited the PolyU LSGI booth. He was briefed on the department’s curriculum development, talent cultivation outcomes, and internationalisation efforts. Mr. Chua expressed strong appreciation for LSGI’s academic strengths in geospatial and smart city domains. This successful participation has further elevated LSGI’s international visibility in the Asia‑Pacific region, strengthened ties with Singapore’s academic community, and laid a solid foundation for future collaborations in talent development, research, and industry‑academia engagement.

We are thrilled to announce that Prof. Jianli CHEN, Chair Professor of Space Geodesy and Earth Sciences (LSGI), has been named one of the winners of the inaugural “PolyU Top 10 Research & Innovation Stories of the Year”. Launched to recognise outstanding achievements with far-reaching impact both locally and globally, this selection and voting campaign showcases PolyU’s most remarkable research and technology translation stories. From 20 finalists announced in 2025, ten awardees were chosen through a combination of professional judging and over 7,700 votes from the public and the PolyU community. These winning stories span five strategic areas — AI and data science, life sciences and healthcare, environment and sustainability, materials science, and smart cities—injecting powerful innovation momentum into Hong Kong’s high-quality development. Prof. CHEN leads a global research effort that uses satellite positioning data to track Greenland’s ice sheet melt behavior and assess its impact on sea-level rise. By integrating modern space geodetic techniques, his team monitors the subsidence of vertical bedrock to quantify summer water storage, offering vital new insights into the role of ice sheets in global environmental changes. Please join us in offering our warmest congratulations to Prof. CHEN on this well-deserved recognition of his pioneering research and global impact!   Press release: English - https://polyu.me/4s8plYJ; Chinese - https://polyu.me/3PUjoky Online coverage: Headline Daily - https://polyu.me/4mFztqQ Headline Daily - https://polyu.me/414Ttcw Ta Kung Pao - https://polyu.me/4dmCKbP Bauhinia - https://polyu.me/4m1vfcL Mirage - https://polyu.me/4tiNeh2  

LSGI Scholar on Ground Penetrating Radar Technology

Prof. Wallace Wai-Lok LAI, Associate Head of the Department of Land Surveying and Geo-Informatics (LSGI), and Yimin ZHOU, Research Assistant, LSGI, were recently featured on HOY TV’s InnoAction. The team demonstrated how integrating multiple sensing technologies ensures reliability in complex environments. While Ground Penetrating Radar (GPR) generates 3D visualizations by analyzing electromagnetic reflections, it requires supplemental positioning in areas with poor satellite reception. By pairing radar data with matched 360-degree panoramic imagery, the system precisely maps anomalies to on-site coordinates, allowing for accurate investigation before any excavation begins. This innovation is a key focus of the newly established Pipeline Robots Joint Laboratory, a collaboration between LSGI, the Water Supplies Department, and a Chinese Mainland partner aimed at advancing pipeline robotics and reducing unnecessary excavation.   Online Coverage: HOY TV - https://polyu.me/4bGfAvO (00:10 - 10:34) i-Cable News - https://polyu.me/4dfezw3 Oriental Daily News - https://polyu.me/4bWhx6k Line Today - https://polyu.me/4uYuW6i
