lakeMinorAxisLength

Minor axis length is defined as the minimum length spanning the convex hull
of a lake.

Lake morphometry metrics are used by limnologists to understand,
among other things, the ecological processes in a lake. Traditionally, these
metrics are calculated by hand, with planimeters, and increasingly with
commercial GIS products. All of these methods work; however, they are either
outdated, difficult to reproduce, or require expensive licenses to use. The
'lakemorpho' package provides the tools to calculate a typical suite
of these metrics from an input elevation model and lake polygon. The metrics
currently supported are: fetch, major axis, minor axis, major/minor axis
ratio, maximum length, maximum width, mean width, maximum depth, mean depth,
shoreline development, shoreline length, surface area, and volume.
