Vegetation maps provide crucial information for ecological studies, biodiversity conservation, vegetation management and restoration, and national strategic decision making. The current vegetation map of China was produced by a team of more than 250 scientists over the course of two decades starting in the 1980s, who spent a huge amount of efforts to manually delineate […]

Development and application of high-throughput crop phenotyping platform Phenomics studies the external performance of crop traits under the interaction of genes and the environment, which provides a new way for crop breeding. The current development of phenomics is far behind the development of genomics due to the lack of high-throughput phenotype platforms and algorithms. In […]

Monitoring and analyzing the spatial and temporal changes of forest resource information Changes of forest quality are composed by the changes in forest structure and species composition, which are usually caused by tree growth, anthropogenic activities (e.g., forest treatment, logging), and environmental disturbances (e.g., drought, flood, and wildfire). To quantitatively assess forest structure changes from […]

3D forest structure parameter extraction and upscaling Individual trees are the basic element composition of a forest stand. The structure characteristic and spatial distribution of trees are the key factors to be surveyed in forest inventory. Lidar, as an emerging active remote sensing technology, provides an automatic, effective and accurate tool for deriving individual tree […]

Development of near-surface remote sensing platforms for forest resource information acquisition Light detection and ranging (lidar), an active remote sensing technology, has the abilities of high-precision and strong penetration to vegetation, which shows unparalleled advantages in obtaining forest resource information comparing with other traditional remote sensing technologies. In this context, we designed and developed a […]

Methods and Applications of Geographic One-class Data We are interested in the theory and applications of geographic one-class data. One common problem with geographic data is that, for a specific geographic event, only occurrence information is available; information about the absence of the event is not available. We define these specific types of geospatial data […]
