LSGI Shanghai Study Tour 2024

A group of five students and academic staff from the Department of Land Surveying and Geo-informatics (LSGI) at the Hong Kong Polytechnic University (PolyU) visited Tongji University (Tongji) in Shanghai for a 6-day summer study tour from 1-6 July, 2024. The aim of this trip was to provide our LSGI students with new insights into the latest development in surveying and geo-informatics through engaging with experts from Tongji's College of Geographic Information and Surveying.   Led by Dr. Songbo WU, Research Assistant Professor at LSGI, the students participated in a series of lectures and hands-on activities at Tongji University. These sessions covered both fundamental theories and cutting-edge applications in surveying. The LSGI students actively engaged with Tongji’s renowned college, participating in discussions and building connections. This enriching experience enhanced the students’ professional knowledge and practical expertise in their field of study.   In addition, the students also gained hands-on experience with Shanghai's urban planning and surveying industry. They visited key institutions like the Shanghai Institute of Surveying and Mapping, Shanghai Astronomical Observatory, and the Shanghai Urban Planning Exhibition Hall. This provided the students with valuable insights into how surveying technology is utilized in areas such as urban planning and disaster prevention, inspiring their future career aspirations. Moreover, the students had the opportunity to experience Shanghai's unique cultural activities like city walks and food sharing events, allowing them to immerse themselves in the local charm of the city.   We are grateful for the warm hospitality provided by Tongji University throughout the summer study tour. This successful summer programme offered valuable learning and growth experiences for students from both institutions, laying the foundation for future collaboration between PolyU and Tongji.

LSGI Scholar’s Granted Project aims to Develop Low-Cost Remote Sensing System for Detecting Illegal Dumping of Construction Waste in Hong Kong

Dr. ZHU Xiaolin, Associate Professor at the Department of Land Surveying & Geo-Informatics (LSGI) at the Hong Kong Polytechnic University (PolyU), was invited to share the findings of his project on the news media "DotDotNews" on 4 June 2024. His project, titled "Developing Low-Cost Remote Sensing System for Detecting Illegal Dumping of Construction Waste in Hong Kong", showcases the impact of granted projects of the Public Policy Research (PPR) Funding Scheme of the Chief Executive's Policy Unit of the HKSAR Government. The project aims to use satellite remote sensing technology to improve the efficiency and coverage of detecting illegal construction waste dumping activities. This technology acts as a "super eye in the sky," capturing hidden illegal dumping behaviors through high-resolution satellite imagery. The current government approach relies on patrols and surveillance cameras, which can be costly and have limited coverage. In contrast, the satellite remote sensing technology can quickly locate illegal dumping activities, enhance monitoring efficiency, and reduce the cost of enforcement. The project's findings will help the government formulate more effective policies to tackle illegal dumping, reduce environmental pollution, protect the ecosystem, and improve the public's quality of life, ultimately creating a better living environment for current and future generations. Thank you for the efforts made by Dr. Zhu and his research team. Online coverage (on 4 June 2024): DotDotNews
