Li Deren, male, Han nationality, is a native of Dantu, Zhenjiang, Jiangsu Province. He received his doctorate from Stuttgart University.
In the 1980s, Li mainly engaged in the study of measuring error theory and treatment methods. In 1982, he initiated the selection iteration method, which deducted the rough difference positioning from the variance estimation. In 1985, he put forward the expandability and reliability theory based on two multi-dimensional optional hypotheses, including the error discovered and differential. He also scientifically "solved the pended problems for more than one hundred years of measurement science." For this research, he received the best monograph prize from Germany's Photogrammetric and Remote Sensing Society in 1988, the "Hansa Aerial Photogrammetric Award".
During the 1990s, Li mainly engaged in the space information science based on the remote sensing, global satellite positioning system (GPS) and geographical information system (GIS) and the scientific research and teaching works of multimedia communication technology. He led and produced the Geostar GIS series products, reformed visual telephones series products and Lideson S type road measuring and steering systems for motor vehicles. He issued more than 270 papers, published 8 monographs, educated more than 50 master's degree students, and more than 60 doctorate degree students. He received the National and Ministry Science and Technology Progress Award, National Excellence of Textbook, Teacher of Excellence Award. He was appointed the chairman of International Photogrammetric and Remote Sensing Society (1SPRS) No.111 Committee (1988-1992 ) and No 112. Committee (1992-1996).
