Prof. Li Deren (Deren Li), scientist in photogrammetry and remote sensing, comes from
Dantu of Zhenjiang, Jiangshu Province. As an important figure and active member of the
scientific community of China, Prof. Li enjoys dual membership of both the Chinese
Academy of Sciences and the Chinese Academy of Engineering. He is a “National Level
Young and Middle-aged Expert with Outstanding Contribution", member of the Euro-Asia
International Academy of Sciences, member of the National Committee of the Chinese
People's Political Consultative Conference (CPPCC). At present, he is Dual-employed
Academicians, professor and PhD supervisor of Department of Aeronautics and
Astronautics, College Of Engineering, Peking University, President of the Chinese Society
of Geodesy, Photogrammetry and Cartography, Director of the National Laboratory for
Information Engineering in Surveying, Mapping and Remote Sensing at WTUSM.
In the 1980s, Prof. Li Deren was mainly engaged in the studies of observation errors and
processing methods. During his studies in Germany since 1982, Li Deren proposed a new
iteration weighted method for gross error location based on a posterior variance
estimation, which has since been named “Deren Li Method". In 1985, he completed
theoretical research in the separability of model errors, which advanced the reliability
theory of Dutch scientists to the separability phase. His theory has “scientifically solved a
hundred-year-baffling problem in geodetic science". The result of this study received the
1988 Best Paper Award of the German Society for Photogrammetry and Remote Sensing,
and Hansa Luftbild Award.In the 1990s, Prof. Li Deren has concentrated on the research
and education in spatial information science and technology represented by remote
sensing (RS), global positioning systems (GPS) and geographic information systems
(GIS). He applies himself diligently to the industrialization of high and new technologies.
He has made unique and original contribution in the areas of theories and methods for
high precision photogrammetric positioning, GPS aerotriangulation, analysis and
processing of SPOT imagery, mathematical morphology and its application in spatial
databases, theories of object-oriented GIS, image understanding and automatic
photointerpretation, multi-media communication and mobile mapping systems, etc.
The research findings have promoted the progress of the technology directly and are
being turned into products.Prof. Li Deren, who has successfully supervised the studies of
over 50 MSc candidates and over 60 PhD candidates, has published over 200 papers and
6 books. He has won more than ten of national and ministerial level prizes, such as The
Sci-tech Progress Award, National Excellent Textbook Award, Award of the Excellent
Educational Achievements, etc.
