The German national forest inventory uses angle count sampling,
a sampling method first published as `Bitterlich, W.: Die Winkelzählmessung.
Allgemeine Forst- und Holzwirtschaftliche Zeitung, 58. Jahrg., Folge 11/12
vom Juni 1947` and extended by Grosenbaugh
(<https://academic.oup.com/jof/article-abstract/50/1/32/4684174>)
as probability proportional to size sampling.
When plots are located near stand boundaries, their sizes and hence
their probabilities need to be corrected.
