hexify (version 0.3.8)

as_sf: 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"), ...)

Value

An sf object

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.

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")
