O_LITraditionally, forest structure is mostly described by vegetative elements; however, the complementary empty space also contributes to the forest spatial structure. C_LIO_LIWe developed an R package (crossing3dforest) to support the entire processing of Terrestrial Laser Scanning point clouds to quantify the size, shape, and connectivity of empty spaces within the mid and low strata of forest stands, using an approach based on the percolation theory. The package functions, which are designed for step-by-step single stand analysis, can be executed sequentially in a pipeline. C_LIO_LIA case study is presented to demonstrate the crossing3dforest potentials for characterising the forest empty space architecture. TLS point clouds collected in ten different pure beech (Fagus sylvatica L.) stands, representative of five distinct forest management regimes, were analysed and characterised. C_LIO_LIThe adopted empty space approach can be integrated into forest structural analysis to identify animal-habitat associations and establish appropriate habitat structure for wildlife management.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
