as_sf: Convert HexData to sf Object

In hexify: Equal-Area Hex Grids on the 'Snyder' 'ISEA' 'Icosahedron'

Convert HexData to sf Object

Description

Converts a HexData object to an sf spatial features object. Can create either point geometries (cell centers) or polygon geometries (cell boundaries).

Usage

as_sf(x, geometry = c("point", "polygon"), ...)

Arguments

x	A HexData object
geometry	Type of geometry: "point" (default) or "polygon"
...	Additional arguments (ignored)

Details

For point geometry, cell centers (cell_cen_lon, cell_cen_lat) are used. For polygon geometry, cell boundaries are computed using the grid specification.

Value

An sf object

Examples

df <- data.frame(lon = c(0, 10, 20), lat = c(45, 50, 55))
result <- hexify(df, lon = "lon", lat = "lat", area_km2 = 1000)

# Get sf points
sf_pts <- as_sf(result)

# Get sf polygons
sf_poly <- as_sf(result, geometry = "polygon")
