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
