Correction Factors for Tree Plot Areas Intersected by Stand Boundaries

Description

The German national forest inventory uses angle count sampling, a sampling method first published by Bitterlich (1947) and extended by Grosenbaugh (1952) as probability proportional to size sampling. When plots are located near stand boundaries, their sizes and hence their probabilities need to be corrected.
