Write sf object to Parquet file

Convert a simple features spatial object from sf and write to a Parquet file using write_parquet. Geometry columns (type sfc) are converted to well-known binary (WKB) format.

Usage

st_write_parquet(obj, dsn, compression = "zstd", ...)

Arguments

obj

object of class sf

dsn

data source name. A path and file name with .parquet extension

compression

algorithm. Default "zstd", recommended for geoparquet

...

additional options to pass to write_parquet

Examples

# read spatial object
nc <- sf::st_read(system.file("shape/nc.shp", package="sf"), quiet = TRUE)

# create temp file
tf <- tempfile(fileext = '.parquet')
on.exit(unlink(tf))

# write out object
st_write_parquet(obj = nc, dsn = tf)

# In Python, read the new file with geopandas.read_parquet(...)
# read back into R
nc_p <- st_read_parquet(tf)
