hexa_area: Polygon to Hexagonal Grids

Description

The function takes a Simple Feature Polygon and a size argument and creates a list with an indexed matrix with coordinates and a Simple Feature object, that consists of hexagonal grids.

Usage

hexa_area(area, size = 500, plot_grid = FALSE)

Value

Returns a list with 2 elements. List element 1 will have the grid cell IDS, and the X and Y coordinates of the centers of each grid cell. List element 2 is the grid as Simple Feature Polygons, which is used for plotting purposes.

Arguments

area

Simple Feature polygon of the site

size

Cell size of the grid in metres

plot_grid

Draw the grid
