In vapour: Access to the 'Geospatial Data Abstraction Library' ('GDAL')

PROJ4 string to WKT

Description

Convert a projstring to Well Known Text.

Usage

vapour_srs_wkt(crs)

Arguments

crs	projection string, see Details.

Details

The function is vectorized because why not, but probably only ever will be used on single element vectors of character strings.

Note that no sanitizing is done on inputs, we literally just 'OGRSpatialReference.SetFromUserInput(crs)' and give the output as WKT. If it's an error in GDAL it's an error in R.

Common inputs are WKT variants, 'AUTH:CODE's e.g. 'EPSG:3031', the 'OGC:CRS84' for long,lat WGS84, 'ESRI:code' and other authority variants, and datum names such as 'WGS84','NAD27' recognized by PROJ itself.

See help for 'SetFromUserInput' in 'OGRSpatialReference', and 'proj_create_crs_to_crs'.
