assmann_layers

Tree heights are attributed to three layers as proposed by
assmann_1961;textualForestElementsR. The layers are called
Top, T, Middle, M, and Bottom, B, and correspond to &gt;80%, &gt;50%, and &gt;0% of
a reference height (usually the height of the highest tree in the stand of
interest).

Provides generic data structures and algorithms for use with forest
mensuration data in a consistent framework. The functions and objects
included are a collection of broadly applicable tools. More specialized
applications should be implemented in separate packages that build on this
foundation. Documentation about 'ForestElementsR' is provided by three
vignettes included in this package. For an introduction to the field of
forest mensuration, refer to the textbooks by Kershaw et al. (2017)
<doi:10.1002/9781118902028>, and van Laar and Akca (2007)
<doi:10.1007/978-1-4020-5991-9>.
