M.DIST (Manual distance)
This function is useful when measuring without
the transponder. Change value with the arrow
keys and confirm with the ON key. The value is
shown in metric or feet.
M. DIST
is the manual
distance to the reference point on the object
where the height is measured. Make sure that
the
T.HEIGHT
is correctly set, i.e. the height to the chosen reference point.
BAF Basal Area Factor
Working with relaskopes or prism can sometimes offer difficulties when in
the forest some trees cover others. The poor sighting can prevent a
correct diameter measuring. With the Vertex built in BAF function, the
minimum tree diameter for trees to be included can be featured.
By measuring the distance from the tree to the plot centre with the Vertex
III the instrument can calculate the minimum diameter for a tree to be
included in the plot.
These BAF factors are available in the Vertex III:
0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 (m2/ha)
or
5, 10, 15, 20, 25, 30, 35, 40, 45, 50 (ft2/acre)
The Vertex III can compensate for an inclination in the terrain when
calculating the minimum diameter, see next chapter.
