How to make a shapefile from pandas Dataframe?
If you haven’t done so already, install GeoPandas (e.g. one of either pip install geopandas or conda install geopandas for Anaconda/Miniconda users). Here is how to read a CSV file with pandas, then use the geopandas.points_from_xy helper function to create a geometry column, then write a shapefile:
How to export geopandas Dataframe into shapefile?
The dataframe I have looks like this: >DriverIOError: Failed to open Shapefile ‘C:\\SHP_python\\&gdf_out.shp’. running the command above I was expecting geopandas to create the &gdf_out.shp and others files .proj, .dbf Do you know how to fix it?

How to convert pandas Dataframe to a geodataframe?
Note that the Point () constructor expects a tuple of float values, so conversion must be included if the dataframe’s column dtypes are not already set to float. Now, convert the pandas DataFrame into a GeoDataFrame.
How to join columns of another Dataframe in pandas?
DataFrame.join(other, on=None, how=’left’, lsuffix=”, rsuffix=”, sort=False) [source] ¶ Join columns of another DataFrame. Join columns with other DataFrame either on index or on a key column. Efficiently join multiple DataFrame objects by index at once by passing a list.
How is a geodataframe combined with a pandas series?
In an attribute join, a GeoSeries or GeoDataFrame is combined with a regular pandas Series or DataFrame based on a common variable. This is analogous to normal merging or joining in pandas. In a Spatial Join, observations from two GeoSeries or GeoDataFrames are combined based on their spatial relationship to one another.
How to merge two datasets in geopandas?
Merging Data ¶ There are two ways to combine datasets in geopandas – attribute joins and spatial joins. In an attribute join, a GeoSeries or GeoDataFrame is combined with a regular pandas Series or DataFrame based on a common variable. This is analogous to normal merging or joining in pandas.
