geopandas.points_from_xy¶
- geopandas.points_from_xy(x, y, z=None, crs=None)¶
Generate GeometryArray of shapely Point geometries from x, y(, z) coordinates.
In case of geographic coordinates, it is assumed that longitude is captured by
xcoordinates and latitude byy.- Parameters
- x, y, ziterable
- crsvalue, optional
Coordinate Reference System of the geometry objects. Can be anything accepted by
pyproj.CRS.from_user_input(), such as an authority string (eg “EPSG:4326”) or a WKT string.
- Returns
- outputGeometryArray
Examples
>>> import pandas as pd >>> df = pd.DataFrame({'x': [0, 1, 2], 'y': [0, 1, 2], 'z': [0, 1, 2]}) >>> df x y z 0 0 0 0 1 1 1 1 2 2 2 2 >>> geometry = geopandas.points_from_xy(x=[1, 0], y=[0, 1]) >>> geometry = geopandas.points_from_xy(df['x'], df['y'], df['z']) >>> gdf = geopandas.GeoDataFrame( ... df, geometry=geopandas.points_from_xy(df['x'], df['y']))
Having geographic coordinates:
>>> df = pd.DataFrame({'longitude': [-140, 0, 123], 'latitude': [-65, 1, 48]}) >>> df longitude latitude 0 -140 -65 1 0 1 2 123 48 >>> geometry = geopandas.points_from_xy(df.longitude, df.latitude, crs="EPSG:4326")
