The relascope, invented by Walter Bitterlich, is a multi-use instrument for forest inventory. It is primarily used to find height of a tree, basal area of a tree and diameter of a tree anywhere along the bole. This instrument is used mostly for applications involving variable radius sample plots in a forest survey.
