getCRS {enmSdmX} | R Documentation |
WKT string for a named coordinate reference system or a spatial object
Description
Retrieve the Well-Known text string (WKT2) for a coordinate reference system (CRS) by name or from a spatial object. The most common usage of the function is to return the WKT2 string using an easy-to-remember name. For example, getCRS('wgs84')
returns the WKT2 string for the WGS84 datum. To get a table of strings, just use getCRS()
.
Usage
getCRS(x = NULL, nice = FALSE, warn = TRUE)
Arguments
x |
This can be any of:
Name of CRS: Each CRS has at least one "alias", which appears in the table returned by getCRS() . You can use any of the aliases to refer to a CRS. Within the function, spaces, case, and dashes in aliases are ignored, but to help make the aliases more memorable, the aliases include them.
-
NULL (default): This returns a table of projections with their aliases (nearly the same as data(crss) ).
An object of class SpatVector , SpatRaster , or sf . If this is a "Spat " or "G " object, then a character vector with the CRS in WKT form is returned. If a sf is supplied, then a crs object is returned in WKT format.
|
nice |
If TRUE , then print the CRS in a formatted manner and return it invisibly. Default is FALSE .
|
warn |
If TRUE (default), then print a warning if the name of the CRS cannot be found.
|
Value
A string representing WKT2 (well-known text) object or a data.frame
.
