Light detection and ranging (lidar) can be used to accurately estimate forest structure attributes using the rich three-dimensional (3D) information within the lidar point clouds， and has been proven to be highly useful for forest inventory practices. Currently, airborne, unmanned aerial vehicle (UAV)-borne, mobile, and terrestrial lidar systems are the most commonly used lidar platforms […]
Forest tree height map of China-1
Spatially continuous estimates of forest canopy height at national to global scales are critical for quantifying forest carbon storage, understanding forest ecosystem processes, and developing forest management and restoration policies to mitigate global climate change. Spaceborne light detection and ranging (lidar) platforms, especially the Global Ecosystem Dynamics Investigation (GEDI) and Ice, Cloud, and land Elevation […]
Intelligent Driving: Essential Tech Research & Development-1
Environmental perception and high-precision positioning are the core research contents of self-driving. These factors help cars obtain accurate real-time positioning information and make correct path planning decisions. However, some problems still exist, including difficulty in recognizing and efficiently realizing complete road mapping, inadequate automation, poor positioning robustness, and so on. To solve these problems, based […]
Animal 3D Ecology: Ecosystem Structure Reconstruction & Application-1
Knowledges about processing of interactions within organisms, between organisms and environment form bedrock of understanding how ecosystem organized. Interactions in forest ecosystem are inferred from patterns of spatial-temporal co-occurrence or avoidance in physical space. Based on the complexity of three-dimensional (3D) ecosystem, ecologists urgently need accurate in-situ data to construct nonlinear relationships and describe complex […]
