vol.m3 {spuRs} | R Documentation |
This function computes the volume of a tree bole given its basal diameter and length, assuming that the bole is a frustum of a geometric solid.
vol.m3(dbh.cm, height.m, multiplier = 0.5)
dbh.cm |
basal diameter in cm. |
height.m |
height in m. |
multiplier |
shape, expressed as a multiplier. |
Commonly-used shapes are:
1/3 conoid
1/2 second-degree parabaloid
1 cylinder
The volume is returned, in units of cubic metres.
