Abstract Purpose of Review Three-dimensional (3D) data on forest structure have
transformed the level of detail and accuracy of forest information. While these 3D data have …

Forest canopy gaps play an important role in forest dynamics. Airborne laser scanning (ALS)
data provide demonstrated capacity to systematically and accurately detect and map canopy …

Canopy cover (CC) is a variable used to describe the status of forests and forested habitats,
but also the variable used primarily to define what counts as a forest. The estimation of CC …

Forest inventory operations have greatly benefitted from remotely sensed data particularly
airborne laser scanning (ALS) which has become a popular technology choice for large …

Digital aerial photogrammetry (DAP) has demonstrated utility across a range of forest
environments as an alternative data source to airborne laser scanning (ALS) for estimating …

Low-cost methods to measure forest structure are needed to consistently and repeatedly
inventory forest conditions over large areas. In this study we investigate low-cost pushbroom …

Digital aerial photogrammetry (DAP) has emerged as a potentially cost-effective alternative
to airborne laser scanning (ALS) for forest inventory methods that employ point cloud data …

The accuracy of vertical position information can be degraded by various sources of error in
digital aerial photogrammetry (DAP) based point clouds. To address this issue, we propose …

Digital stereo aerial photographs are periodically updated in many countries and offer a
viable option for the regular update of information on forest variables. We compared the …

Dense matching is crucial for 3D scene reconstruction since it enables the recovery of scene
3D geometry from image acquisition. Deep Learning (DL)-based methods have shown …
