About Me
I am Chenghan Yang, a Ph.D. candidate at the School of Geography and Ocean Science, Nanjing University. My research focuses on urban remote sensing, GeoAI, geospatial big data, and street-view imagery. I am committed to advancing the applications of 3S technologies (GIS, RS, and GNSS) to develop transformative geospatial technologies that change lives and support sustainable development.
