研究领域

Dr. Guang Zheng is a Professor of Remote Sensing at the International Institute for Earth System Science (ESSI) of Nanjing University (NJU). His researches focus on: (1) characterizing three-dimensional (3-D) forest canopy structure using the light detection and ranging (lidar) data generated from various platforms, including Space-bore lidar, Aerial Laser Scanning (ALS), Mobile Laser Scanning (MLS), Terrestrial Laser Scanning (TLS), and UAV-based laser scanning (ULS) data; (2) investigating the interactions and relationships between forest canopy structure, radiation regime, and physiological processes; and (3) monitoring and updating forest aboveground biomass (AGB) by combining multi-source remotely sensed data and process-based ecological model. He got his Ph.D. from the Remote Sensing and Geospatial Analysis Laboratory (RSGAL)at the University of Washington (UW). He worked closely with Precision Forestry Cooperative (PFC)to understand the forest canopy structure and its implications and interactions with the radiation regime and physiological processes of the terrestrial ecosystem.
