st_as_text {sf} | R Documentation

## Return Well-known Text representation of simple feature geometry or coordinate reference system

### Description

Return Well-known Text representation of simple feature geometry or coordinate reference system

### Usage

    ## S3 method for class 'crs'
    st_as_text(x, ..., projjson = FALSE, pretty = FALSE)

    st_as_text(x, ...)

    ## S3 method for class 'sfg'
    st_as_text(x, ...)

    ## S3 method for class 'sfc'
    st_as_text(x, ..., EWKT = FALSE)

### Arguments

`x` | object of class `sfg`, `sfc` or `crs`
`...` | modifiers; in particular `digits` can be passed to control the number of digits used
`projjson` | logical; if TRUE, return projjson form (requires GDAL 3.1 and PROJ 6.2), else return well-known-text form
`pretty` | logical; if TRUE, print human-readable well-known-text representation of a coordinate reference system
`EWKT` | logical; if TRUE, print SRID=xxx; before the WKT string if `epsg` is available

### Details

The returned WKT representation of simple feature geometry conforms to the simple features access specification and extensions (known as EWKT, supported by PostGIS and other simple features implementations for addition of a SRID to a WKT string).

### Examples

    st_as_text(st_point(1:2))
    st_as_text(st_sfc(st_point(c(-90,40)), crs = 4326), EWKT = TRUE)
