Research Centre for Artificial Intelligence in Geomatics

The Research Centre for Artificial Intelligence in Geomatics (RCAIG) aims to set up as a joint effort between five academic departments in three faculties and will fully utilise and expand the potentials of JC STEM Lab of Earth Observations. The RCAIG focuses on the development of innovative AI technologies for solving environmental and societal challenges in geomatics, with the goal of becoming a global R&D hub in GeoAI.

Principal Investigator

Professor Qihao WENG

Professor Qihao Weng is Chair Professor of Geomatics and Artificial Intelligence at The Hong Kong Polytechnic University. A renowned scholar, Professor Weng has made notable contributions in the fields of remote sensing, GIScience, artificial intelligence, urban and environmental research. He is currently the Lead of the Group on Earth Observation’s (GEO) Global Urban Observation and Information Initiative.

Professor Weng’s research on remote sensing applications has promoted understanding of urban environmental and ecological systems, land-use and land-cover changes, and human-environment interactions. By bridging methodological gaps between geography, landscape ecology, and environmental science, his work has enabled holistic solutions to pressing environmental, ecological, and climatic challenges. Throughout his research career, Professor Weng has authored an impressive 279 articles (journal articles, chapters, etc.) and 14 books. Per Google Scholar, as of August 7, 2023, he has been cited more than 30,900 times (H-index of 77), and 68 of his publications have more than 100 citations each. His research has been supported by major funding agencies including the NSF, NASA, USAID, National Geographic, Microsoft, Hong Kong Research Grant Council, and the Hong Kong Jockey Club Charities Trust.
