geopandas.GeoDataFrame.set_crs¶

GeoDataFrame.set_crs(self, crs=None, epsg=None, inplace=False, allow_override=False)¶

Set the Coordinate Reference System (CRS) of the GeoDataFrame.

If there are multiple geometry columns within the GeoDataFrame, only the CRS of the active geometry column is set.

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

Parameters

crspyproj.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.
epsgint, optional if crs is specified: EPSG code specifying the projection.
inplacebool, default False: If True, the CRS of the GeoDataFrame will be changed in place (while still returning the result) instead of making a copy of the GeoDataFrame.
allow_overridebool, default False: If the the GeoDataFrame already has a CRS, allow to replace the existing CRS, even when both are not equal.
