R Documentation

Extract phenological metrics

Description

This function computes and returns the approximate pole of inaccessibility (visual centre) for a polygon using the quadtree-based algorithm implemented in polylabelr::poi(), accepting an input in the same format of sf_centroid() (sf, sfc or sfg) and returning an output in the same format of x.

Usage

st_poi(x, ..., precision)

Arguments

`x`	object of class `sfg`, `sfc` or `sf`
`...`	Ignored
`precision`	The precision to use when computing the centre (passed to `polylabelr::poi()`), in the `x` unit. If missing, by default it is used the 1/1000 of the mean square root of the area of inputs.
