csv file holding field recorded data returning a list holding field and other key data provided as arguments. Field measures to be taken on logs and branches include:
azimuth): mean angle of orientation of the branch or log measured from the base of the tree (usually with magnetic north as reference, measured clockwise), mandatory
dBase): diameter at insertion point on the stem, for branches, diameter of the lower section for logs, mandatory
dTip): always 0 for branches, diameter of the higher section for logs, defaults to 0, mandatory only for logs
length): length of logs or branches, mandatory for logs, mandatory for branches only if their slenderness coefficient is to be computed
tipD): length of branch or log projection on the ground, starting from tree base to tip of branch or log, mandatory
height): height of branch insertion on the stem or height of lower section of the log, to be used to compute z coordinate of CM, defaults to NA, mandatory only for z determination of CM
tilt): mean branch tilt or log tilt from the horizontal plane (eg a vertical branch is 90 degrees, an horizontal branch is 0 degrees), to be used to compute z coordinate of CM, defaults to 0, mandatory only for z determination of CM. Note however that the tree tip should be considered as a branch, not a log, in order to account for foliage biomass. In this case the tilt value should be recorded otherwise it would default to 0, ie an horizontal branch
toBePruned): a boolean value, defaults to FALSE, optional
pathToTip): a boolean value TRUE on logs and branches that make part of the ``main stem'' of the tree, defaults to FALSE, optional
