Forest-PointNet: A Deep Learning Model for Vertical Structure Segmentation in Complex Forest Scenes

Remote Sensing, 2023
The vertical structure of forest ecosystems influences and reflects ecosystem functioning. Terrestrial laser scanning (TLS) enables the rapid acquisition of 3D forest information and subsequent reconstruction of the vertical structure, which provides new

Characterizing the vertical structure of forests in the Brazilian Amazon. [PDF]

Commun Earth Environ
Little is known about the structure of tropical forests despite its critical role in the provisioning of ecosystem services. Here we assess the vertical structure of forests in the Brazilian Amazon with a large-scale airborne LiDAR dataset. We show that fire has greater impact in the lowest forest strata, differently from selective logging and ...

On the estimation of forest vertical structure from multibaseline polarimetric SAR data [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Forest characterization and biomass estimation by means of remote sensing systems are nowadays “hot topics” within the remote sensing community, given their importance in the terrestrial carbon budget. In fact, forest vertical structure is a key variable for assessing biodiversity and structural degradation and/or regeneration. Moreover, the (vertical)
