Professor Shi’s research has centred on urban informatics and smart cities, artificial intelligence-based change detection and target recognition in remote sensing imagery, spatial big data analysis and quality control, mobile mapping, and three-dimensional modelling. Through national research programmes and international scientific collaboration, he has contributed to the development of smart-city technologies, methodologies for spatial data quality assessment and assurance, and applications of geospatial artificial intelligence to urban management and environmental monitoring. His work has been published extensively in peer-reviewed journals and international conferences and has addressed the integration of remote sensing, geographic information systems, and artificial intelligence for urban and spatial information applications. In 2023, he was listed as an eligible candidate in the election process for membership of the Chinese Academy of Sciences. Through sustained research, leadership of joint laboratories and research institutes, and international collaboration, Professor Shi has contributed to connecting advances in geospatial information science with practical applications in smart-city development, spatial data infrastructure, urban management, and sustainable urbanisation.
