South Dakota State University continues to rank among the best in the United States and in the world in the ShanghaiRanking’s 2021 Global Ranking of Academic Subjects.
SDSU is fourth in the U.S. and 19th in the world in the 2021 rankings, which are based on research productivity in remote sensing. The university was also fourth in the U.S. in the 2020 rankings and 14th in the world.
In the 2017 rankings, SDSU was seventh in the U.S. and 27th in the world. It was 12th in the U.S. and 42nd worldwide in the 2018 list. In 2019, SDSU ranked 22nd in the world and fifth in the U.S.
“Our faculty in the SDSU Geospatial Sciences Center of Excellence continue to produce high-quality research in remote sensing that impacts South Dakota and the world. This is a well-deserved recognition,” said Bob Watrel, who leads the Department of Geography and Geospatial Sciences.
Xiaoyang Zhang, co-director of the Geospatial Sciences Center of Excellence, uses remote sensing to track emissions from wildfires. These models are used to track air quality and then deliver warnings for those at risk, for example with lung ailments, when conditions are poor.
Remote sensing data is used to detect drought and disease due to changes in the greenness of crops as well as evapotranspiration. It can monitor how climate change is affecting the growing seasons, such as are they getting longer or shorter, starting earlier or going later?
ShanghaiRanking uses four metrics to determine research productivity—number of publications authored, percentage of articles with international collaborators, number of publications in top journals and average impact, which is measured by citations, of the papers published according to a well-established independent database.
