Concatenate a sf object into a geojson polygon

Take single points from geographical coordinates and convert it into a geojson 'Polygon' string using st_buffer.

sf_to_geojson(lonlat, dist = 0.00001, nQuadSegs = 2L, ...)

Arguments

lonlat	an object of class 'sf' and geometry type 'POINT' or 'POLYGON'
dist	numeric, buffer distance for all lonlat
nQuadSegs	integer, number of segments per quadrant
...	further arguments passed to sf methods

Value

An object of class 'geosjon' for each row in lonlat

Examples

# \donttest{
# random geographic points within bbox(10, 12, 45, 47)
library("sf")

set.seed(123)
lonlat <- data.frame(lon = runif(5, 10, 12),
                     lat = runif(5, 45, 47))

lonlat <- st_as_sf(lonlat, coords = c("lon","lat"))

gjson <- sf_to_geojson(lonlat)
# }
