sampling the forest
This type of inventory is built on a preliminary analysis of the forest population. The information obtained is mainly used to inform early management choices. On a regional or overall area basis, the inventory data are condensed.
Developing a virtual forest model allows further quantitative and qualitative assessment of the forest stands and of forest management practices, including elements regarding natural capital, ecosystem services and biodiversity.
The vertical structure of the forest can be easily observed through satellite observations.
Information such as textures, granulation, spectral variations can be used as predictors in a machine learning algorithm to determine forest characteristics needed for planning and management.
Moreover, this activity can produce continuous data (raster data at pixel level constitution using VIRTSILV machine learning algorithm) using discontinuous data collected from the ground (plot data with ground-truth information processed by VIRTSILV sample plot module)

A.I. Decision forest maps
Forest stands are used as timber inventory units, forestry data containers and operation units in timberland management. Stands can be made either on operational or on biological basis. Biological stands tend to be smaller and more detailed than stands made on operational basis. Typical stand criteria have been timber size, density and species, as well as site type.
A faster and more precise way of creating spatial decision-making maps for forest management is to combine digital twin data (basal area, volume, dbh, h) into a simplified, homogeneous stand map
In VIRTSILV workflow generalized allometric equations are used to determine biomass (dry weight). Equations regarding stem volume or biomass of tree components (stem, branches, leaves and total area) at dbh or dbh ar used based on international research papers and on the unique shape of the scanned trees.
