GeoSeries

Constructor

geopolars.GeoSeries

Bases: pl.Series

Extension of polars.Series to handle geospatial vector data.

to_crs

to_crs(
    from_crs: str | pyproj.crs.CRS,
    to_crs: str | pyproj.crs.CRS,
) -> GeoSeries

Transform all geometries in a GeoSeries to a different coordinate reference system.

For now, you must pass in both from_crs and to_crs. In the future, we'll handle the current CRS automatically.

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.

Parameters:

from_crs (str | pyproj.crs.CRS) –

Origin coordinate system. The value can be anything accepted by pyproj.CRS.from_user_input(), such as an authority string (eg "EPSG:4326") or a WKT string.
to_crs (str | pyproj.crs.CRS) –

Destination coordinate system. The value can be anything accepted by pyproj.CRS.from_user_input(), such as an authority string (eg "EPSG:4326") or a WKT string.

Returns:

GeoSeries –

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

to_geopandas

to_geopandas() -> geopandas.GeoSeries

Converts this GeoSeries to a geopandas.GeoSeries.

This operation clones data. This requires that geopandas and pyarrow are installed.
