シュピーゲル・レラスコープ
The Relaskop are principally known in connection with angle-count sampling ( ACS ),
a method which determines basal area density in forests by a simple counting method.
The Relaskop automatically corrects for any inclination in the line of sight,
making it possible to easily find the stand basal area in square meters per hectare
either at breast height (1.3m above the ground) or any other height.
The Relaskop offer quite q few other measurement applications in practical and
scientific forestry.
For example:
•Determining the horizontal distance,with automatic correction for the angle of inclination.
•Measurement of total tree height, or heights to particular upper stem diameters.
•Measurements of upper stem diameters at particular heights.
•Quick determination of "slenderness"( heights/diameter ratio) of standing trees.
•Determination of form heights, and the volumes of standing trees by Presler’s formula.
•Relaskops are the principle instrument of " variable plot sampling ”
which has the special advantage of selecting a basal-area weighted distribution.
In addition the appropriate stem numbers per hectale can be derived from ACS
selection sample.
While the optical-mechanical functions of all Spiegel-Relaskop are the same,
they are made with four different types of sale, according to their principal use.
