Description

A dataset from 1991 containing 1203 sample plots observations from a forest inventory using cluster-sampling. The large phase comprises 298 clusters. Terrestrial information of the stem number as well as the basal area is available for a systematic subsample of 73 clusters. Auxiliary information at all 2103 sample plots were derived by stand maps. Originally the inventory was carried out as a twophase inventory and has been artificially extended to a threephase inventory for demonstration purposes.
