LSGI Scholar, Prof. George Zhizhao LIU was appointed as the Founding Chair of Hong Kong Branch of the 142-year-old Canadian Institute of Geomatics (CIG).
We are pleased to announce that Prof. George Zhizhao LIU, a Professor at the Department of Land Surveying and Geo-Informatics (LSGI), The Hong Kong Polytechnic University (PolyU) was recently appointed as the Founding Chair of Hong Kong Branch of the 142-year-old Canadian Institute of Geomatics (CIG).
Prof. Liu is an internationally respected scholar with both industrial and academic experiences in basic research as well as applications of geomatics technologies. Over the years, Prof. Liu’s Micro-Laboratory of Atmospheric Research and Geomatics Engineering (Micro-LARGE) has made significant contributions to the community through unique developments and innovations in various areas, including Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) precise positioning algorithms and data quality analysis, ionosphere scintillation monitoring and 3D Total Electron Content (TEC) modeling, impact of space weather on satellite navigation and flight operation, monitoring of atmospheric water vapor and 3D modeling, retrieval and calibration of satellite remote sensing water vapor data, and assimilation of atmospheric water vapor in Numerical Weather Prediction (NWP) models.
His Micro-LARGE Lab is the first one internationally to study and evaluate the impact of space weather on flight operation from an economic cost perspective and to propose response strategies, which was highly commended by senior scientist at the NASA JPL and was selected as a research highlight in the Nature Reviews Earth & Environment Journal (IF: 42.1). Multiple algorithms developed by the Micro-LARGE for GNSS data processing have been widely used by research groups in many universities, research institutions and industries worldwide. Prof. Liu’s Micro-LARGE Lab is the first one in the world to calibrate all-weather (including cloudy condition) near-infrared (NIR) band satellite remote sensing water vapor data and also the first one to assimilate all-weather NIR band satellite remote sensing water vapor data into NWP.
Founded in 1882, the Canadian Institute of Geomatics (CIG) was originally known as the Canadian Institute of Surveying (CIS) until it was renamed in 1999. CIG is a professional organization that was initially established to support the surveying profession in Canada. Over the years, as the field of surveying evolved and expanded to include other geospatial technologies, the organization also evolved to reflect these changes. The establishment of the Hong Kong Branch is to establish a strong professional connection between the Canadian geomatics community and the one in Hong Kong and Asia.
Geomatics, also known as geospatial technology, includes the tools and techniques used in land surveying, remote sensing, cartography, geographic information systems (GIS), global-navigation satellite systems (GPS, GLONASS, Galileo, Beidou), photogrammetry, and related forms of earth mapping.
The institute aims to lead the advancement of geomatics in Canada and worldwide and offers a platform for geospatial information professionals worldwide to share ideas, collaborate on research, and promote the use of geomatics in various sectors of the economy. CIG organizes conferences, seminars, and workshops, and publishes a peer-reviewed scientific journal called “Geomatica”. The institute also provides scholarships and awards to recognize individuals who have made significant contributions to the field of geomatics.
