Fast loading and saving of GeoJSON

The {yyjsonr} package offers fast loading and saving of GeoJSON files compared to the GDAL used by, for example, {sf} and {terra}. However, GDAL has more features like filtering based on criteria.

Code

library("sf")
library("yyjsonr")
options(timeout = 600) # connection timeout

## download dataset
url = "https://github.com/paleolimbot/geoarrow-data/releases/download/v0.0.1/nshn_land_poly.gpkg"
download.file(url, "nshn_land_poly.gpkg", mode = "wb")
data = read_sf("nshn_land_poly.gpkg") # 24037 polygons x 11 attributes
data = st_transform(data, "EPSG:4326") # transform to WGS84

Data saving

system.time( sf::write_sf(data, "test.geojson") )

##    user  system elapsed 
##   62.80    1.10   63.92

system.time( yyjsonr::write_geojson_file(data, "test.geojson") )

##    user  system elapsed 
##    1.09    0.71    2.21

Data loading

system.time( sf::read_sf("test.geojson") )

##    user  system elapsed 
##   22.14    1.67   23.83

system.time( yyjsonr::read_geojson_file("test.geojson") )

##    user  system elapsed
