Generate a rectangular grid of hexagon polygons — hexify_grid_rect • hexify

Creates hexagon polygons covering a rectangular geographic region.

Usage

hexify_grid_rect(
  minlon,
  maxlon,
  minlat,
  maxlat,
  area,
  aperture = 3L,
  resround = "nearest",
  radius_km = EARTH_RADIUS_KM
)

Arguments

minlon, maxlon: Longitude bounds
minlat, maxlat: Latitude bounds
area: Target cell area in km^2
aperture: Grid aperture: 3, 4, or 7
resround: Resolution rounding: "nearest", "up", or "down"
radius_km: Radius of the body, in kilometers, or a body name such as "mars" (default Earth). See hex_grid.

Value

sf object with hexagon polygons covering the specified region
