max_dist {remotePARTS}

calculate maximum distance among a table of coordinates

Description

calculate maximum distance among a table of coordinates

Usage

max_dist(coords, dist_FUN = "distm_km")

Arguments

coords

the coordinate matrix (or dataframe) from which a maximum distance is desired.

dist_FUN

the distance function used to calculate distances

Details

First the outermost points are found by fitting a convex hull in Euclidean space. Then, the distances between these outer points is calculated with dist_FUN, and the maximum of these distances is returned

This is a fast, simple way of determining the maximum distance.

Value

The maximum distance between two points (units determined by dist_FUN)
