hexa_area: Polygon to Hexagonal Grid Tessellation

In windfarmGA: Genetic Algorithm for Wind Farm Layout Optimization

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(shape, size = 500, plotGrid = FALSE)

Arguments

shape	Simple Feature Polygon of the considered area
size	The cellsize of the grid in meters. Default is 500
plotGrid	Logical value indicating whether the results should be plotted. Default is 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.

## Exemplary input Polygon with 2km x 2km:
Poly <- sf::st_as_sf(sf::st_sfc(
  sf::st_polygon(list(cbind(
    c(4498482, 4498482, 4499991, 4499991, 4498482),
    c(2668272, 2669343, 2669343, 2668272, 2668272)))), 
  crs = 3035
))
HexGrid <- hexa_area(Poly, 100, TRUE)
