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.

Advanced Urban Remote Sensing Workshop Successfully Held

From Dec 3rd to 4th, 2022, an international conference, Advanced Urban Remote Sensing Workshop (AURSW), was successfully held at The University of Hong Kong (HKU). The workshop was co-chaired by Professor Peng GONG, Vice-President and Pro-Vice-Chancellor (Academic Development) of HKU, and Professor Qihao WENG, Chair Professor of The Hong Kong Polytechnic University (PolyU).

Ir Professor Christopher Chao, Vice President (Research and Innovation) of PolyU, Chair Professor of Thermal and Environmental Engineering, and Director of Policy Research Centre for Innovation and Technology (PReCIT), attended the workshop and gave an opening speech on behalf of PolyU. As conference co-chair, Prof. Weng Qihao, a Chair Professor of Geomatics and Artificial Intelligence at Dept of LSGI, and Director of JC STEM Lab of Earth Observations at PolyU was invited to give a keynote lecture on “Three Decades of Urban Remote Sensing in Perspective”. Prof. Weng also introduced to the audience the newly founded IEEE Geoscience and Remote Sensing Society Hong Kong Chapter, in which he serves as the Chair. Researchers and students from PolyU, HKU, CUHK, CityU, HKBU and HKUST and other organizations have joined this chapter. The workshop was conducted in a hybrid mode. It consists of one and a half day’s workshop and a half-day field trip. Nearly 30 LSGI academic staff, research staff, and students participated in the workshop actively. Prof. Wu Chen (Head of LSGI), Prof. Xiaoli Ding (Director of Research Institute of Land and Space), and Prof. John WZ Shi (Director of Smart Cities Research Institute) attended the workshop. Prof. Xiaoli Zhu, Associate Professor, gave a talk on Remote sensing image fusion for urban environment monitoring.

PhD student Jiafei Xu talked on Enhanced all-weather precipitable water vapor retrieval from MODIS near infrared bands based on machine learning. The workshop attracted top urban remote sensing experts from USA, Europe, and China, and brought together researchers from academic institutions and end users from the industry for a comprehensive discussion on the newest research in the field of remote sensing after the three years of the pandemic. Young researchers and students were involved in many in-depth discussions with senior researchers in the urban remote sensing field.

PolyU and Hong Kong Space Museum collaborate on “Moon | Mars VR” interactive exhibit, simulating a spacewalking journey for visitors

The Hong Kong Polytechnic University (PolyU) has collaborated with the Hong Kong Space Museum to showcase an interactive exhibit “Moon | Mars VR”, starting today for one year. The virtual reality exhibit, powered by PolyU’s cutting-edge technology that assists the Nation’s space missions, allows the public to experience spacewalking and explore the landing sites of Chang’e-4 and Tianwen-1 spacecrafts on the Moon and Mars. The launch ceremony was held today at the Museum. The VR exhibit makes use of data provided by the relevant space agencies of China and the PolyU research team led by Professor WU Bo, Fiona Cheung Professor in Spatial Science, Associate Director of Research Centre for Deep Space Explorations and Associate Head of the Department of Land Surveying and Geo-Informatics, to create a virtual reality environment of the landing sites on the Moon and Mars, allowing visitors to virtually experience spacewalking on the two celestial bodies. Invited by the China National Space Administration, this VR system was also recently showcased at the China International Aviation & Aerospace Exhibition held at Zhuhai and enthusiastically received by audience. The launch ceremony today was officiated by Prof. Wu Bo and the Curator of the Hong Kong Space Museum Mr Timothy HO Man Hung. Prof. Wu is the developer of the innovative 3D topographic mapping and intelligent geomorphological analysis techniques which contributed to landing site mapping and selection for China’s Chang’e-3, Chang’e-4, and Chang’e-5 lunar missions, as well as the Tianwen-1 mission to Mars. Tying in with the theme of the exhibit, Prof. Wu was also invited to deliver a public lecture titled “Space Exploration: A Journey to the Heavenly Questions”, discussing recent space missions by China and other countries exploring the Moon and Mars, and introducing the application of topographic mapping, remote sensing, artificial intelligence and other technologies in support of these space exploration missions. Prof. Wu also discussed the prospects for further space exploration and education with the audience. Prof. Wu said, “As the only Hong Kong institution contributing to the Nation’s astronautical projects, PolyU has been deeply involved in China’s lunar and Mars missions. We are pleased to collaborate with the Hong Kong Space Museum in showcasing this exhibit, inviting the public to experience some of the scientific research achievements of PolyU and the Nations’ space exploration accomplishments over the years. Looking forward, it is hoped that more events and exhibitions with a focus on space technology can be held to promote greater awareness and interest among the public and young people.” To further contribute to the development of China's aerospace technology, PolyU has established the “Research Centre for Deep Space Explorations”, and also signed a cooperation agreement with the Academy of Aerospace Propulsion Technology in China to establish the “Joint Research Centre of Advanced Aerospace Propulsion Technology”. The University fully supports the selection of payload specialists in Hong Kong for China’s manned space programme, and previously held a seminar on campus to encourage outstanding young scholars to apply. PolyU will continue to realise our vision to benefit the Nation and Hong Kong by nurturing talents and pursuing cutting-edge scientific research. The “Moon | Mars VR” exhibit is jointly presented by the Leisure and Cultural Services Department and PolyU, and jointly organised by the Hong Kong Space Museum and the Planetary Remote Sensing Laboratory of PolyU’s Research Centre for Deep Space Explorations, and supported by the China National Space Administration’s Information Office.
