A project named “Antiquity and Heritage Lost, Found and Revealed: Promotion of 21st Century Geo-spatial Technologies” led by Prof. Wallace LAI Wai-lok, Member of the Research Institute for Land and Space (RILS), Associate Head (Teaching) and Professor of the Department of Land Surveying and Geo-informatics, has been granted HK$3.22 million from the General Support Programme under the Innovation and Technology Fund (ITF-GSP) of the Innovation and Technology Commission of the HKSAR Government.
This two-year project, in collaboration with Hong Kong Baptist University and local amateur war historians, aims to uncover and document the city’s concealed historical sites using advanced geospatial technologies. By employing techniques such as geo-referencing, airborne and terrestrial laser scanning, and geophysical technologies, the team is capturing detailed images of buried wartime relics and antiquities, bringing these lost historical artefacts back to light.
To foster community involvement in STEAM (science, technology, engineering, arts, and mathematics) education, the team will organise public programmes such as guided visits to cultural and wartime heritage sites, STEAM-focused seminars, interactive workshops, and immersive exhibitions. The team has collaborated with a wide range of stakeholders including government bodies, universities and industry partners, science magazines, non-governmental organisations and local village communities to enhance public engagement and advance the application of geospatial innovations in uncovering Hong Kong’s hidden historical stories.
In May 2025, the team expanded the study scope to Malacca, Malaysia, where they conducted 3D scanning and mapping of historic structures, including the Porta de Santiago and St. Paul’s Church. By integrating digitised historical maps with modern scanning technologies, the team identified remnants of long-buried colonial fortifications. Further expeditions to other regions in Malaysia and Indonesia have been planned.
