xugrid.UgridDataArrayAccessor.set_crs#

UgridDataArrayAccessor.set_crs(crs: pyproj.CRS | str = None, epsg: int = None, allow_override: bool = False)[source]#

Set the Coordinate Reference System (CRS) of a UGRID topology.

NOTE: The underlying geometries are not transformed to this CRS. To transform the geometries to a new CRS, use the to_crs method.

Parameters:

crs (pyproj.CRS, optional if epsg is specified) – The value can be anything accepted by pyproj.CRS.from_user_input(), such as an authority string (eg “EPSG:4326”) or a WKT string.
epsg (int, optional if crs is specified) – EPSG code specifying the projection.
allow_override (bool, default False) – If the the UGRID topology already has a CRS, allow to replace the existing CRS, even when both are not equal.
