hexify (version 0.3.10)

hexify_assign: Assign hex cells ('ISEA3H', aperture 3) for lon/lat

Description

Forward -> quantize (Z3) -> center (face) -> inverse to lon/lat. Optionally return polygons (sf), in which case sf must be installed.

Usage

hexify_assign(
  lon,
  lat,
  effective_res,
  match_dggrid_parity = TRUE,
  make_polygons = FALSE
)

Value

data.frame with id, face, effective_res, center_lon, center_lat; if make_polygons=TRUE, an sf with geometry column.

Arguments

lon, lat

numeric vectors (same length), degrees.

effective_res

integer effective resolution (>= 1).

match_dggrid_parity

logical; TRUE matches 'ISEA3H' parity used by 'dggridR'.

make_polygons

logical; if TRUE, return an sf with hex polygons.
