GeoSeries.to_crs(crs=None, epsg=None)#

Returns a GeoSeries with all geometries transformed to a new coordinate reference system.

This docstring was copied from geopandas.geoseries.GeoSeries.to_crs.

Some inconsistencies with the Dask version may exist.

Transform all geometries in a GeoSeries to a different coordinate reference system. The crs attribute on the current GeoSeries must be set. Either crs or epsg may be specified for output.

This method will transform all points in all objects. It has no notion of projecting entire geometries. All segments joining points are assumed to be lines in the current projection, not geodesics. Objects crossing the dateline (or other projection boundary) will have undesirable behavior.

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 output projection.
