Spatial - Exports an sf object.

Exports an sf object to a specified output.

spExportSpatial(sfobj, savedata_opts = NULL)

Arguments

sfobj

sf class R object. Spatial object to export.

savedata_opts

List. See help(savedata_options()) for a list of options for saving data. If out_layer = NULL, default = 'datsp'.

Value

An sf spatial object is written to outfolder.

Details

Wrapper for sf::st_write function.

Note

If out_fmt='shp':
The ESRI shapefile driver truncates variable names to 10 characters or less. Variable names are changed before export using an internal function (trunc10shp). Name changes are output to the outfolder, 'out_layer'_newnames.csv.

If sf object has more than 1 record, it cannot be exported to a shapefile.

# Set up data from FIESTA
WYbh <- spImportSpatial(system.file("extdata",
                                    "sp_data/WYbighorn_adminbnd.shp",
                                    package = "FIESTA"))

# Export data with spExportSpatial
spExportSpatial(WYbh,
                savedata_opts = list(out_dsn = "WYbh.shp", 
                                     outfolder = tempdir(), 
                                     overwrite_dsn = TRUE))
