Chengquan Huang has devoted a decade in studies of land cover and vegetation dynamics using remotely sensed data. He has been engaged in several projects that were national to continental in scale, including the USGS Multi-Resolution Land Characteristics (MRLC) 2001 project, the joint USGS-US Forest Service LANDFIRE project, the NASA LEDAPS project, and the NASA North American Forest Dynamics project. Currently he is leading efforts to quantify forest change at national to global scales using Landsat data, and is developing approaches for mapping forest structure and biomass change by integrating field inventory data, airborne or space borne lidar, and Landsat derived forest disturbance history.
