In arete: Automated REtrieval from TExt

Check EOO differences between two sets of coordinates

Description

Calculate EOO for two sets of coordinates for a practical assessment of data proximity.

Usage

compare_IUCN(x, y, plots = TRUE, verbose = TRUE)

Arguments

x	data.frame. With two columns containing latitude and longitude. Considered during reporting as data from a LLM.
y	data.frame. With the same formatting as x. Considered during reporting as the ground truth.
plots	logical. Determines if plots should be printed.
verbose	logical. Determines if output should be printed.

Details

Extent of occurrence (EOO) is defined as "the area contained within the shortest continuous imaginary boundary which can be drawn to encompass all the known, inferred or projected sites of present occurrence of a taxon, excluding cases of vagrancy"

Value

list with two values, the percentage of y that is part of the intersection with x and y and the percentage of x that is part of the intersection with x and y

Examples

set_a = matrix(
  c(54.30379, -25.48098, 54.21251,	-25.47146, 59.53277, -20.37448, 55.59712,
 -22.39599, 55.47244, -26.30330, 61.39205,	-21.12364, 56.24010, -24.40347),
 ncol = 2, byrow = TRUE 
)

set_b = matrix(
c(54.30379,	-25.48098, 111.42100,	-19.00400, 54.21251, -25.47146, 59.53277,
  -20.37448, 55.59125, -22.39599, 55.47244,	-26.30330, 61.39205, -21.12364,
   56.24010,	-24.40347),
   ncol = 2, byrow = TRUE
 )
