The “main stem” is not very clearly defined. Most softwood species (ie Picea, Abies, Pseudotsuga etc.) have only one stem given by their dominant apex. Hardwood species (Quercus, Tilia etc) and some softwood species (eg Pinus pinea) do not exhibit a dominant apex and branches often enlarge and grow taller than the apex. In these latter cases one has to select an appropriate path from tree base to tree tip, according to what may be considered the “main stem” of the tree. Both in former and latter cases the path selection has to be laid down in the fieldData
data frame.
1 | logPathSelection(treeData)

treeData |
A named list that includes a |
a data frame subsetted from the fieldData
data frame having TRUE
selected branches and logs, with three columns: azimuth
, length
, tilt
. The first row if filled with zeros.
Selected branches and logs have a TRUE
value in the pathToTip
column. This is a necessary step
towards anchor force detemrination, as the returned data frame has to be submitted to getPlinthForce
