Combining shapefiles in Python / GeoPandas

Question

I have three polygon shapefiles which overlap each other. Let's call them:

• file_one.shp (polygon Name is 1)
• file_two.shp (polygon Name is 2)
• file_three.shp (polygon Name is 3)

I want to combine them and keep the values like this.

How can I achieve the result (As shown in the figure) in Python, please?

Thanks!

Answer 1

If you want to simply create one shapefile from files you've mentioned you can try following code (I assume that shapefiles has same columns).

import pandas as pd
import geopandas as gpd

gdf1 = gpd.read_file('file_one.shp')
gdf2 = gpd.read_file('file_two.shp')
gdf3 = gpd.read_file('file_three.shp')

gdf = gpd.GeoDataFrame(pd.concat([gdf1, gdf2, gdf3]))
