LSGI funded by ITF for technology promotion on unfolding the lost WWII heritage in HK

How many WWII heritage and brave stories are still hidden and buried in Hong Kong’s forests and natural terrain? Wartime heritages and histories are whittled away elsewhere but innovative geo-spatial and geophysical technologies can unfold and sustain their legacy. Ir Dr. Wallace Lai and Dr. Yan Wai Yeung from LSGI have obtained a $4.75M Innovation Technology Fund (ITF) to develop and promote airborne and terrestrial geo-spatial/geophysical technologies as a means on baseline assessment on wartime archaeology and subsequent historical interpretation. Other team members of the ITF project include historians, archaeologists, forensic anthropologists, geologists, and geomorphologist from Hong Kong Baptist University, The University of Hong Kong and The Chinese University of Hong Kong. The 2-year project "Unfolding the lost WWII heritage: promotion of geo-spatial and geophysical technologies" will start in Jan 2023. It is supported by five Government departments/bureau (AFCD, LandsD, WSD, CEDD and CSTB), and an industrial in-kind sponsor Camptopia, a campsite in Fanling which will provide venue for the Art-Tech exhibition "Lest we forget: The 80th Anniversary of WWII in HK reconstructed by Art-Tech". Through a variety of public engagement activities, we look forward to the development and promotion of the technologies to be blended in an holistic Art-Tech approach for historical interpretation, heritage conservation & tourism, and STEAM education.
