writeVector: Write SpatVector data to a file

In terra: Spatial Data Analysis

Write SpatVector data to a file

Description

Write a SpatVector to a file. You can choose one of many file formats.

Usage

## S4 method for signature 'SpatVector,character'
writeVector(x, filename, filetype=NULL, layer=NULL, insert=FALSE,
    overwrite=FALSE, options="ENCODING=UTF-8")

Arguments

x	SpatVector
filename	character. Output filename
filetype	character. A file format associated with a GDAL "driver" such as "ESRI Shapefile". See gdal(drivers=TRUE) or the GDAL docs. If NULL it is attempted to guess the filetype from the filename extension
layer	character. Output layer name. If NULL the filename is used
insert	logical. If TRUE, a new layer is inserted into the file, if the format allows it (e.g. GPKG allows that). See vector_layers to remove a layer
overwrite	logical. If TRUE, filename is overwritten
options	character. Format specific GDAL options such as "ENCODING=UTF-8". Use NULL or "" to not use any options

Examples

v <- vect(cbind(1:5,1:5))
crs(v) <- "+proj=longlat +datum=WGS84"
v$id <- 1:length(v)
v$name <- letters[1:length(v)]
tmpf1 <- paste0(tempfile(), ".gpkg")
writeVector(v, tmpf1, overwrite=TRUE)
x <- vect(tmpf1)

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
tmpf2 <- paste0(tempfile(), ".gpkg")
writeVector(v, tmpf2, overwrite=TRUE)
y <- vect(tmpf2)
