In geojsonsf: GeoJSON to Simple Feature Converter

sf to GeoJSON

Description

Converts 'sf' objects to GeoJSON

Usage

sf_geojson(
  sf,
  atomise = FALSE,
  simplify = TRUE,
  digits = NULL,
  factors_as_string = TRUE
)

Arguments

sf	simple feature object
atomise	logical indicating if the sf object should be converted into a vector of GeoJSON objects
simplify	logical indicating if sf objects without property columns should simplify (TRUE) into a vector of GeoJSON, or return a Featurecollection with empty property fields (FALSE). If atomise is TRUE this argument is ignored.
digits	integer specifying the number of decimal places to round numerics. numeric values are coorced using as.integer, which may round-down the value you supply. Default is NULL - no rounding
factors_as_string	logical indicating if factors should be treated as strings. Defaults to TRUE.

Value

vector of GeoJSON

Examples

## Not run: 
library(sf)
sf <- sf::st_sf(geometry = sf::st_sfc(list(sf::st_point(c(0,0)), sf::st_point(c(1,1)))))
sf$id <- 1:2
sf_geojson(sf)
sf_geojson(sf, atomise = T)

ls <- st_linestring(rbind(c(0,0),c(1,1),c(2,1)))
mls <- st_multilinestring(list(rbind(c(2,2),c(1,3)), rbind(c(0,0),c(1,1),c(2,1))))
sfc <- st_sfc(ls,mls)
sf <- st_sf(sfc)
sf_geojson( sf )
sf_geojson( sf, simplify = FALSE )
