Create buffers around sf geometries in km

Source: R/spatial_ops.R
pk_buffer.Rd

Reprojects to UTM Zone 42N internally so buffer distances are in kilometres, then returns buffers in the original CRS.

Usage

pk_buffer(x, dist_km)

Arguments

x

An sf object.

dist_km

Numeric. Buffer distance in kilometres.

Value

Returns an sf object with the same attributes as x but with geometries transformed to buffers of radius dist_km kilometres.

The output CRS is identical to the input CRS (reprojected back from UTM Zone 42N after buffering). This ensures buffers are circular in projected space with accurate kilometre distances.

Examples

districts <- get_districts()
buffered <- pk_buffer(districts, dist_km = 10)
