Professor Tang Guoan


Doctor, Professor, Doctor’s Tutor, Chief of the course

Department Head of GIS in School of Geographical Science, Nanjing Normal University

Assistant Director of Key GIS Lab of Jiangsu Province.

He was born in Ningbo of Zhejiang province in June, 1961. In 1982, he graduated from Northwest University, majored in Physical Geography and then worked in Water and Soil Research Institute of Shanxi Province. In 1987, he received his master’s degree from the same school, majored in Cartography and Remote Sensing and became a teacher in it. In 1995, he went to study in Salzburg University in Austria and three years later, got the doctor's degree of Geographical Information System. He returned to Northwest University to teach in 1999. One year later, he came to Institute of Water and Soil Conservation, Chinese Academy of Science, to do research work as a senior visiting scholar. From 2001 to 2003, he engaged in post-doctor's research in Northwest University and in the last year, he moved to work in Nanjing Normal University. Now, he is the department head of GIS in School of Geographical Science and assistant director of Key GIS Lab of Jiangsu Province. Moreover he is vice director of Education Committee of the GIS Association of China as well as the member of Cartography and GIS Committee of Chinese Geography Society. In the recent years, he mainly devoted himself in research work such as the uncertainty of DEM, digital topographical analysis of loess plateau, data mining and knowledge discovery for National Fundamental Geo-Database. He successively takes charge in several scientific research projects titled “Fund Project of National Natural Science”, “National 863 Project”, “Key Science and Tech Project of Ministry of Education”, “Fund Project towards Outstanding Young of Ministry of Education”, “Scientific Fund of Chinese Post-Doctors” and “Fund Project towards Outstanding Returned Student Abroad of Ministry of Education”. Professor Tang teaches Geographical Information System, GIS Spatial Analysis, Digital Ground Model and Geomatics Application, Superior GIS etc. for graduates and post-graduates for a long time. He has received multiple prizes on scientific research and teaching.
