3.3. Dividing a woodpile
3.3.1. Basics
With very narrow road conditions, it may occur that a woodpile cannot be measured as a
whole, since the camera opening angle cannot cover the entire wood piling height. In this
case, the woodpile can be divided into an upper and a lower part.
These are measured in two separate measuring runs, which leads to two separate woodpile
measurement results. Both parts are stored separately and cannot be merged to form just one
measurement. Therefore, it is important to internally agree on a common Woodpile ID exten-
sion for a split woodpile.
A general recommendation for the best possible extension cannot be given at this point, since
the most diverse woodpile number concepts are used. Most of the time, however, you can use
one of the following examples, where XYZ123 is the original number of the woodpile:
 XYZ123_1 and XYZ123_2
 XYZ123-1 and XYZ123-2
 XYZ123 (1) and XYZ123 (2)
In addition, a note can be stored in the note field (see Chapter A.5.2.9) so that the two
amounts can be combined later.
3.3.2. Procedure
Use the cross-hair plates described in Chapter C.1 to mark the dividing line between the upper
and lower woodpile part. Look for a suitable edge log on the relevant woodpile, so that the
regular polygonal course crosses the cross-hair as directly as possible.
Now first perform the measurement of the lower woodpile part. Form the polygonal course
basically as described in Chapter A.3.2.3, but delete all polygon vertices between the two
cross-hairs, so that the two upper vertices are connected with a direct line (see Figure 13).
After transmitting the lower part, measure the upper part accordingly, so that now the two
lower corner points are connected with a direct line - without additional polygon vertices (see
Figure 14).
In Figures 15 to 18 you can see detail sections of the areas in which the polygonal courses lie
on the cross-hairs.
