He has also served as a board member of The International Association of Chinese Professionals in Geographic Information Science (CPGIS). He was a NASA Earth System Science Fellow and a recipient of the Robert N. Colwell Fellowship from the American Society for Photogrammetry and Remote Sensing (ASPRS).

Title: Spatiotemporal Mining of Earth Observation Data: Challenges and Opportunities


Recent advances in remote sensing technologies have led to the acquisition of massive amounts of earth observation (EO) data from a wide range of platforms and sensors with various spatial resolutions and temporal frequencies. The rich spatial and temporal information in EO data presents an unprecedented opportunity to better understand our changing planet. However, the massiveness, complexity, and diversity of EO data also pose special challenges to automatically identify meaningful patterns and relationships from EO data for scientific discovery. While existing data mining techniques have shown great potential for EO data, there is still a strong need for developing more specialized EO data mining tools to keep up the explosive growth in EO data and address new challenges faced by the scientific community. This talk will first give an overview of existing spatiotemporal data mining techniques applied to EO data. It will then discuss emerging challenges and opportunities of developing effective spatiotemporal data mining techniques for geospatial information extraction and knowledge discovery.
