sampleType |
character, Specifies how the plot is sampled among fixed area plot or variable area plot, must be either V for variable area plot or F for fixed area plot. |
blowUp |
numeric, Specifies the blowup factor. For fixed area plot, it is calculated as 1/plotarea. For variable area plot, it is basal area factor (BAF). |
treeWeight |
numeric, Specifies whether a tree is zero counted (tree is out), one time counted (regular count) or two times counted (double counted) in the walk through sampling protocal. |
plotWeight |
numeric, Specifies how a plot is measured, i.e., full plot measured (valued as 1), half plot measured (valued as 2) or quarter plot measured (valued as 4). |
treeBasalArea |
numeric, When plot is measured using variable area plot, this value must be given, otherwise, can be missing |
