Forest Remote Sensing Faces New Era With 10-cm Satellite Imagery

Scientists from the Aerospace Information Research Institute (AIR), Chinese Academy of Sciences (CAS), have proposed a new algorithm called AGAR, which makes it possible to detect tree heights only using 10-cm stereoscopic imagery, according to a study published in Remote Sensing of Environment on May 10. Current knowledge on the limitation of stereoscopic imagery is ...

Study Reveals Generation Mechanism Of Radiative Effects On Novel Active Optical Hyperspectral Lidar System

Study Reveals Generation Mechanism Of Radiative Effects On Novel Active Optical Hyperspectral Lidar System

Both the geometric and spectral information of the target are available with the hyperspectral light detection and ranging (LiDAR) in a single measurement. This advanced technique extends the scope of imaging spectroscopy to spectral three-dimensional (3D) sensing. However, two major geometric radiative effects exist in hyperspectral LiDAR, namely, the distance effect and incidence angle effect, ...

Aerial System Obtains Glacier Data

Aerial System Obtains Glacier Data

The Chinese Academy of Sciences and Wuhan University are conducting a sky-ground scientific experiment to test the condition of glaciers in the Haibei Tibetan autonomous prefecture in Northwest Qinghai province. The experiment has applied radars in three bands — P-band, L-band and Very High Frequency — and undertaken 11 flights, among which seven carried out ...

Seasonal Effects On Aboveground Biomass Estimation In Mountainous Deciduous Forests

Seasonal Effects On Aboveground Biomass Estimation In Mountainous Deciduous Forests

Researchers from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) have found that the proportion of sunlit background visible in remote sensing images controls the vertical distribution of stereoscopic point clouds. The higher the proportion of visible sunlit background, the stronger the ability to detect the understory terrain. The team ...
